The optional
<code class="literal">
FOR CHANNEL
<em class="replaceable">
<code>

</em>
</code>
clause enables you
to name which replication channel the statement applies to.
Providing a
<code class="literal">
FOR CHANNEL
<em class="replaceable">
<code>
channel
</code>
</em>
</code>
clause applies the
<code class="literal">
START REPLICA
</code>
statement to a specific
replication channel. If no clause is named and no extra channels
exist, the statement applies to the default channel. If a
<code class="literal">
START REPLICA

statement does not have a
channel defined when using multiple channels, this statement
starts the specified threads for all channels. See
<a class="xref" href="replication-channels.html" title="19.2.2 Replication Channels">
Section 19.2.2, “Replication Channels”

<p>
The replication channels for Group Replication
(
<code class="literal">
group_replication_applier

and
<code class="literal">
group_replication_recovery

) are managed
automatically by the server instance.
<code class="literal">
START

<code class="literal">
group_replication_recovery

channel, and
should only be used with the
<code class="literal">
group_replication_applier
</code>
channel when Group
Replication is not running. The
<code class="literal">
group_replication_applier
</code>
channel only has an
applier thread and has no receiver thread, so it can be started
if required by using the
<code class="literal">

The
<code class="literal">
UNTIL

clause makes the replica start
replication, then process transactions up to the point that you
specify in the
<code class="literal">
UNTIL
</code>
clause, then stop again.
The
<code class="literal">
UNTIL
</code>
clause can be used to make a
replica proceed until just before the point where you want to
skip a transaction that is unwanted, and then skip the
transaction as described in
<a class="xref" href="replication-administration-skip.html" title="19.1.7.3 Skipping Transactions">
Section 19.1.7.3, “Skipping Transactions”
</a>
. To identify a
transaction, you can use
<a class="link" href="mysqlbinlog.html" title="6.6.9 mysqlbinlog — Utility for Processing Binary Log Files">
<span class="command">
<strong>
mysqlbinlog
</strong>
</span>
</a>

<a class="link" href="show-binlog-events.html" title="15.7.7.3 SHOW BINLOG EVENTS Statement">
<code class="literal">
SHOW BINLOG EVENTS
</code>
</a>
statement.
</p>
<p>
You can also use the
<code class="literal">
UNTIL
</code>
clause for
debugging replication by processing transactions one at a time
or in sections. If you are using the
<code class="literal">
UNTIL
</code>
clause to do this, start the replica with
<a class="link" href="replication-options-replica.html#option_mysqld_skip-replica-start">
<code class="option">
--skip-replica-start
</code>
</a>
to prevent
the SQL thread from running when the replica server starts.
Remove the option or system variable setting after the procedure
is complete, so that it is not forgotten in the event of an
unexpected server restart.
</p>
<p>
The
<a class="link" href="show-replica-status.html" title="15.7.7.35 SHOW REPLICA STATUS Statement">
<code class="literal">
SHOW REPLICA STATUS
</code>
</a>
statement
includes output fields that display the current values of the
<code class="literal">
UNTIL
</code>
condition. The
<code class="literal">
UNTIL
</code>
condition lasts for as long as the affected threads are still
running, and is removed when they stop.
</p>
<p>
The
<code class="literal">
UNTIL
</code>
clause operates on the replication
applier thread (
<code class="literal">
SQL_THREAD
</code>
option). You can
use the
<code class="literal">
SQL_THREAD
</code>
option or let the replica
default to starting both threads. If you use the
<code class="literal">
IO_THREAD
</code>
option alone, the
<code class="literal">
UNTIL
</code>
clause is ignored because the applier
thread is not started.
</p>
<p>
The point that you specify in the
<code class="literal">
UNTIL
</code>
clause can be any one (and only one) of the following options:
</p>
<div class="variablelist">
<dl class="variablelist">
<dt>
<span class="term">
<code class="literal">
SOURCE_LOG_FILE
</code>
and
<code class="literal">
SOURCE_LOG_POS
</code>
</span>
</dt>
<dd>
<p>
These options make the replication applier process
transactions up to a position in its relay log, identified
by the file name and file position of the corresponding
point in the binary log on the source server. The applier
thread finds the nearest transaction boundary at or after
the specified position, finishes applying the transaction,
and stops there. For compressed transaction payloads,
specify the end position of the compressed
<code class="literal">
Transaction_payload_event
</code>
.
</p>
<p>
These options can still be used when the
<code class="literal">
GTID_ONLY
</code>
option was set on the
<a class="link" href="change-replication-source-to.html" title="15.4.2.2 CHANGE REPLICATION SOURCE TO Statement">
<code class="literal">

<code class="literal">
RELAY_LOG_FILE

and
<code class="literal">

</span>
</dt>
<dd>
<p>
These options make the replication applier process
transactions up to a position in the replica’s relay
log, identified by the relay log file name and a position
in that file. The applier thread finds the nearest
transaction boundary at or after the specified position,
finishes applying the transaction, and stops there. For
compressed transaction payloads, specify the end position
of the compressed
<code class="literal">
Transaction_payload_event
</code>
.
</p>
<p>
These options can still be used when the
<code class="literal">
GTID_ONLY

option was set on the
<a class="link" href="change-replication-source-to.html" title="15.4.2.2 CHANGE REPLICATION SOURCE TO Statement">
<code class="literal">

</p>
</dd>
<dt>
<span class="term">
<code class="literal">
SQL_BEFORE_GTIDS
</code>
</span>
</dt>
<dd>
<p>
This option makes the replication applier start processing
transactions and stop when it encounters any transaction
that is in the specified GTID set. The encountered
transaction from the GTID set is not applied, and nor are
any of the other transactions in the GTID set. The option
takes a GTID set containing one or more global transaction
identifiers as an argument (see
<a class="xref" href="replication-gtids-concepts.html#replication-gtids-concepts-gtid-sets" title="GTID Sets">
GTID Sets
</a>
).
Transactions in a GTID set do not necessarily appear in
the replication stream in the order of their GTIDs, so the
transaction before which the applier stops is not
necessarily the earliest.
</p>
</dd>
<dt>
<span class="term">
<code class="literal">
SQL_AFTER_GTIDS
</code>
</span>
</dt>
<dd>
<p>
This option makes the replication applier start processing
transactions and stop when it has processed all of the
transactions in a specified GTID set. The option takes a
GTID set containing one or more global transaction
identifiers as an argument (see
<a class="xref" href="replication-gtids-concepts.html#replication-gtids-concepts-gtid-sets" title="GTID Sets">
GTID Sets
</a>
).
</p>
<p>
With
<code class="literal">
SQL_AFTER_GTIDS
</code>
, the replication
threads stop after they have processed all transactions in
the GTID set. Transactions are processed in the order
received, so it is possible that these include
transactions which are not part of the GTID set, but which
are received (and processed) before all transactions in
the set have been committed. For example, executing
<code class="literal">
START REPLICA UNTIL SQL_AFTER_GTIDS =
3E11FA47-71CA-11E1-9E33-C80AA9429562:11-56
</code>
causes the replica to obtain (and process) all
transactions from the source until all of the transactions
having the sequence numbers 11 through 56 have been
processed, and then to stop without processing any
additional transactions after that point has been reached.
</p>
<p>
In older versions of MySQL, this option could not be used
with
<a class="link" href="replication-options-replica.html#sysvar_replica_parallel_workers">
<code class="literal">
replica_parallel_workers >
1
</code>
</a>
. In MySQL 8.4, this is no longer
an issue, and
<code class="literal">
SQL_AFTER_GTIDS
</code>
can be
used without causing the replica to fall back into
single-threaded mode.
</p>
</dd>
<dt>
<span class="term">
<code class="literal">
SQL_AFTER_MTS_GAPS
</code>
</span>
</dt>
<dd>
<p>
For a multithreaded replica only (with
<a class="link" href="replication-options-replica.html#sysvar_replica_parallel_workers">
<code class="literal">
replica_parallel_workers
</code>
</a>
> 0), this option makes the replica process
transactions up to the point where there are no more gaps
in the sequence of transactions executed from the relay
log. When using a multithreaded replica, there is a chance
of gaps occurring in the following situations:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
The coordinator thread is stopped.
</p>
</li>
<li class="listitem">
<p>
An error occurs in the applier threads.
</p>
</li>
<li class="listitem">
<p>
<a class="link" href="mysqld.html" title="6.3.1 mysqld — The MySQL Server">
<span class="command">
<strong>
mysqld
</strong>
</span>
</a>
shuts down unexpectedly.
</p>
</li>
</ul>
</div>
<p>
When a replication channel has gaps, the replica’s
database is in a state that might never have existed on
the source. The replica tracks the gaps internally and
disallows
<a class="link" href="change-replication-source-to.html" title="15.4.2.2 CHANGE REPLICATION SOURCE TO Statement">
<code class="literal">
CHANGE REPLICATION SOURCE
TO
</code>
</a>
statements that would remove the gap
information if they executed.
</p>
<p>
All replicas are multithreaded by default. When
<a class="link" href="replication-options-replica.html#sysvar_replica_preserve_commit_order">
<code class="literal">
replica_preserve_commit_order=ON
</code>
</a>
on the replica (the default), gaps should not occur except
in the specific situations listed in the description for
this variable. If
<code class="literal">
replica_preserve_commit_order
</code>
is
<code class="literal">
OFF
</code>
, the commit order of transactions
is not preserved, so the chance of gaps occurring is much
larger.
</p>
<p>
If GTIDs are not in use and you need to change a failed
multithreaded replica to single-threaded mode, you can
issue the following series of statements, in the order
shown:

This chapter discusses stored database objects that are defined in
terms of SQL code that is stored on the server for later execution.
</p>
<p>
Stored objects include these object types:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Stored procedure: An object created with
<a class="link" href="create-procedure.html" title="15.1.17 CREATE PROCEDURE and CREATE FUNCTION Statements">

</a>
and invoked
using the
<a class="link" href="call.html" title="15.2.1 CALL Statement">
<code class="literal">

</a>
statement. A
procedure does not have a return value but can modify its
parameters for later inspection by the caller. It can also
generate result sets to be returned to the client program.

Stored function: An object created with
<a class="link" href="create-function.html" title="15.1.14 CREATE FUNCTION Statement">
<code class="literal">
CREATE FUNCTION

and used much
like a built-in function. You invoke it in an expression and it
returns a value during expression evaluation.

8.1.7 Client Programming Security Guidelines

Client applications that access MySQL should use the following
guidelines to avoid interpreting external data incorrectly or
exposing sensitive information.

Handle External Data Properly
</h4>
</div>
</div>
</div>
<p>
Applications that access MySQL should not trust any data entered
by users, who can try to trick your code by entering special or
escaped character sequences in Web forms, URLs, or whatever
application you have built. Be sure that your application
remains secure if a user tries to perform SQL injection by
entering something like
<code class="literal">
; DROP DATABASE
mysql;
</code>
into a form. This is an extreme example, but
large security leaks and data loss might occur as a result of
hackers using similar techniques, if you do not prepare for
them.
</p>
<a class="indexterm" name="idm46045252397904">
</a>
<a class="indexterm" name="idm46045252396832">
</a>
<p>
A common mistake is to protect only string data values. Remember
to check numeric data as well. If an application generates a
query such as
<code class="literal">
SELECT * FROM table WHERE
ID=234
</code>
when a user enters the value
<code class="literal">
234
</code>
, the user can enter the value
<code class="literal">
234 OR 1=1
</code>
to cause the application to
generate the query
<code class="literal">
SELECT * FROM table WHERE ID=234 OR
1=1
</code>
. As a result, the server retrieves every row in
the table. This exposes every row and causes excessive server
load. The simplest way to protect from this type of attack is to
use single quotation marks around the numeric constants:
<code class="literal">
SELECT * FROM table WHERE ID='234'
</code>
. If the
user enters extra information, it all becomes part of the
string. In a numeric context, MySQL automatically converts this
string to a number and strips any trailing nonnumeric characters
from it.
</p>
<p>
Sometimes people think that if a database contains only publicly
available data, it need not be protected. This is incorrect.
Even if it is permissible to display any row in the database,
you should still protect against denial of service attacks (for
example, those that are based on the technique in the preceding
paragraph that causes the server to waste resources). Otherwise,
your server becomes unresponsive to legitimate users.

Many application programming interfaces provide a means of
escaping special characters in data values. Properly used, this

<p>
It is the application's responsibility to intercept errors that
occur as a result of executing SQL statements with the MySQL
database server and handle them appropriately.
</p>
<p>
The information returned in a MySQL error is not gratuitous
because that information is key in debugging MySQL using
applications. It would be nearly impossible, for example, to
debug a common 10-way join
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT
</code>
</a>
statement without providing information regarding which
databases, tables, and other objects are involved with problems.
Thus, MySQL errors must sometimes necessarily contain references
to the names of those objects.
</p>
<p>
A simple but insecure approach for an application when it
receives such an error from MySQL is to intercept it and display
it verbatim to the client. However, revealing error information
is a known application vulnerability type
(
<a class="ulink" href="http://cwe.mitre.org/data/definitions/209.html" target="_blank">
CWE-209
</a>
)
and the application developer must ensure the application does
not have this vulnerability.
</p>
<p>
For example, an application that displays a message such as this
exposes both a database name and a table name to clients, which
is information a client might attempt to exploit:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-none"><div class="docs-select-all right" id="sa78583715"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-none">ERROR 1146 (42S02): Table 'mydb.mytable' doesn't exist</code></pre>
</div>
<p>
Instead, the proper behavior for an application when it receives
such an error from MySQL is to log appropriate information,
including the error information, to a secure audit location only
accessible to trusted personnel. The application can return
something more generic such as
<span class="quote">
“
<span class="quote">
Internal Error
</span>
”
</span>
to
the user.

<p>
You can use the
<code class="literal">
update()
</code>
method to modify one
or more records in a table. The
<code class="literal">
update()

method works by filtering a query to include only the records to
be updated and then applying the operations you specify to those
records.

To replace a city name in the city table, pass to the
<code class="literal">
set()

method the new city name. Then, pass to
the
<code class="literal">

method the city name to locate
and replace. The following example replaces the city Peking with
Beijing.

This section also covers the related

Lost connection

</code>
error.
</p>
<p>
The most common reason for the
<code class="literal">
MySQL server has gone
away
</code>
error is that the server timed out and closed
the connection. In this case, you normally get one of the
following error codes (which one you get is operating
system-dependent).

By default, the server closes the connection after eight hours
if nothing has happened. You can change the time limit by
setting the
<a class="link" href="server-system-variables.html#sysvar_wait_timeout">
<code class="literal">
wait_timeout
</code>
</a>
variable when you start
<a class="link" href="mysqld.html" title="6.3.1 mysqld — The MySQL Server">
<span class="command">
<strong>
mysqld
</strong>
</span>
</a>
. See
<a class="xref" href="server-system-variables.html" title="7.1.8 Server System Variables">
Section 7.1.8, “Server System Variables”
</a>
.
</p>
<p>
If you have a script, you just have to issue the query again
for the client to do an automatic reconnection. This assumes
that you have automatic reconnection in the client enabled
(which is the default for the
<code class="literal">
mysql
</code>
command-line client).
</p>
<p>
Some other common reasons for the
<code class="literal">
MySQL server has
gone away
</code>
error are:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
You (or the db administrator) has killed the running
thread with a
<a class="link" href="kill.html" title="15.7.8.4 KILL Statement">
<code class="literal">

</a>
statement or a
<a class="link" href="mysqladmin.html" title="6.5.2 mysqladmin — A MySQL Server Administration Program">
<span class="command">
<strong>

</span>
</a>
command.
</p>
</li>
<li class="listitem">
<p>
You tried to run a query after closing the connection to
the server. This indicates a logic error in the
application that should be corrected.

A client application running on a different host does not
have the necessary privileges to connect to the MySQL

<li class="listitem">
<p>
You got a timeout from the TCP/IP connection on the client
side. This may happen if you have been using the commands:
<a class="ulink" href="/doc/c-api/8.4/en/mysql-options.html" target="_top">
<code class="literal">
mysql_options(...,
MYSQL_OPT_READ_TIMEOUT,...)
</code>
</a>
or
<a class="ulink" href="/doc/c-api/8.4/en/mysql-options.html" target="_top">
<code class="literal">
mysql_options(...,
MYSQL_OPT_WRITE_TIMEOUT,...)
</code>
</a>
. In this case
increasing the timeout may help solve the problem.
</p>
</li>
<li class="listitem">
<p>
You have encountered a timeout on the server side and the
automatic reconnection in the client is disabled (the
<code class="literal">
reconnect
</code>
flag in the
<code class="literal">
MYSQL
</code>
structure is equal to 0).
</p>
</li>
<li class="listitem">
<p>
You are using a Windows client and the server had dropped
the connection (probably because
<a class="link" href="server-system-variables.html#sysvar_wait_timeout">
<code class="literal">
wait_timeout
</code>
</a>
expired)
before the command was issued.
</p>
<p>
The problem on Windows is that in some cases MySQL does
not get an error from the OS when writing to the TCP/IP
connection to the server, but instead gets the error when
trying to read the answer from the connection.
</p>
<p>
The solution to this is to either do a
<a class="ulink" href="/doc/c-api/8.4/en/mysql-ping.html" target="_top">
<code class="literal">
mysql_ping()
</code>
</a>
on the
connection if there has been a long time since the last
query (this is what Connector/ODBC does) or set
<a class="link" href="server-system-variables.html#sysvar_wait_timeout">
<code class="literal">
wait_timeout
</code>
</a>
on the
<a class="link" href="mysqld.html" title="6.3.1 mysqld — The MySQL Server">
<span class="command">
<strong>
mysqld
</strong>
</span>
</a>
server so high that it in
practice never times out.
</p>
</li>
<li class="listitem">
<p>
You can also get these errors if you send a query to the
server that is incorrect or too large. If
<a class="link" href="mysqld.html" title="6.3.1 mysqld — The MySQL Server">
<span class="command">
<strong>
mysqld
</strong>
</span>
</a>
receives a packet that is too
large or out of order, it assumes that something has gone
wrong with the client and closes the connection. If you
need big queries (for example, if you are working with big
<a class="link" href="blob.html" title="13.3.4 The BLOB and TEXT Types">
<code class="literal">
BLOB
</code>
</a>
columns), you can
increase the query limit by setting the server's
<a class="link" href="server-system-variables.html#sysvar_max_allowed_packet">
<code class="literal">
max_allowed_packet
</code>
</a>
variable, which has a default value of 64MB. You may also
need to increase the maximum packet size on the client
end. More information on setting the packet size is given
in
<a class="xref" href="packet-too-large.html" title="B.3.2.8 Packet Too Large">
Section B.3.2.8, “Packet Too Large”

<a class="link" href="replace.html" title="15.2.12 REPLACE Statement">
<code class="literal">
REPLACE
</code>
</a>
statement that
inserts a great many rows can also cause these sorts of
errors. Either one of these statements sends a single
request to the server irrespective of the number of rows
to be inserted; thus, you can often avoid the error by
reducing the number of rows sent per
<a class="link" href="insert.html" title="15.2.7 INSERT Statement">
<code class="literal">
INSERT
</code>
</a>
or
<a class="link" href="replace.html" title="15.2.12 REPLACE Statement">
<code class="literal">

</a>
.
</p>
</li>
<li class="listitem">
<p>
It is also possible to see this error if host name lookups
fail (for example, if the DNS server on which your server
or network relies goes down). This is because MySQL is
dependent on the host system for name resolution, but has
no way of knowing whether it is working—from MySQL's
point of view the problem is indistinguishable from any
other network timeout.
</p>
<p>
You may also see the
<code class="literal">
MySQL server has gone
away
</code>
error if MySQL is started with the
<a class="link" href="server-system-variables.html#sysvar_skip_networking">
<code class="literal">
skip_networking
</code>
</a>
system
variable enabled.
</p>
<p>
Another networking issue that can cause this error occurs
if the MySQL port (default 3306) is blocked by your
firewall, thus preventing any connections at all to the
MySQL server.
</p>
</li>
<li class="listitem">
<p>
You can also encounter this error with applications that
fork child processes, all of which try to use the same
connection to the MySQL server. This can be avoided by
using a separate connection for each child process.

should concentrate on finding the reason for the crash. Start
by checking whether issuing the query again kills the server
again. See

This section discusses internal locking; that is, locking
performed within the MySQL server itself to manage contention
for table contents by multiple sessions. This type of locking is
internal because it is performed entirely by the server and
involves no other programs. For locking performed on MySQL files
by other programs, see

<p>
To avoid
<a class="link" href="glossary.html#glos_deadlock" title="deadlock">
deadlocks
</a>
when
performing multiple concurrent write operations on a single
<code class="literal">
InnoDB
</code>
table, acquire necessary locks at
the start of the transaction by issuing a
<code class="literal">
SELECT ...
FOR UPDATE
</code>
statement for each group of rows expected
to be modified, even if the data change statements come later
in the transaction. If transactions modify or lock more than
one table, issue the applicable statements in the same order
within each transaction. Deadlocks affect performance rather
than representing a serious error, because
<code class="literal">
InnoDB
</code>
automatically
<a class="link" href="glossary.html#glos_deadlock_detection" title="deadlock detection">
detects
</a>
deadlock conditions by default and rolls back one of the
affected transactions.
</p>
<p>
On high concurrency systems, deadlock detection can cause a
slowdown when numerous threads wait for the same lock. At
times, it may be more efficient to disable deadlock detection
and rely on the
<a class="link" href="innodb-parameters.html#sysvar_innodb_lock_wait_timeout">
<code class="literal">
innodb_lock_wait_timeout
</code>
</a>
setting for transaction rollback when a deadlock occurs.

Table-Level Locking

<p>
MySQL uses
<a class="link" href="glossary.html#glos_table_lock" title="table lock">
table-level
locking
</a>
for
<code class="literal">
MyISAM
</code>
,
<code class="literal">
MEMORY
</code>
, and
<code class="literal">
MERGE
</code>
tables, permitting only one session to update those tables at
a time. This locking level makes these storage engines more
suitable for read-only, read-mostly, or single-user
applications.
</p>
<p>
These storage engines avoid
<a class="link" href="glossary.html#glos_deadlock" title="deadlock">
deadlocks
</a>
by always
requesting all needed locks at once at the beginning of a
query and always locking the tables in the same order. The
tradeoff is that this strategy reduces concurrency; other
sessions that want to modify the table must wait until the
current data change statement finishes.
</p>
<p>
Advantages of table-level locking:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Relatively little memory required (row locking requires
memory per row or group of rows locked)
</p>

<li class="listitem">

MySQL grants table write locks as follows:
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
If there are no locks on the table, put a write lock on
it.
</p>
</li>
<li class="listitem">
<p>
Otherwise, put the lock request in the write lock queue.
</p>
</li>
</ol>
</div>
<p>
MySQL grants table read locks as follows:
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
If there are no write locks on the table, put a read lock
on it.
</p>
</li>
<li class="listitem">
<p>
Otherwise, put the lock request in the read lock queue.
</p>
</li>
</ol>
</div>
<p>
Table updates are given higher priority than table retrievals.
Therefore, when a lock is released, the lock is made available
to the requests in the write lock queue and then to the
requests in the read lock queue. This ensures that updates to
a table are not
<span class="quote">
“
<span class="quote">
starved
</span>
”
</span>
even when there is
heavy
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT
</code>
</a>
activity for the
table. However, if there are many updates for a table,
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT
</code>
</a>
statements wait until
there are no more updates.

The
<code class="literal">
MyISAM

concurrent inserts to reduce contention between readers and
writers for a given table: If a
<code class="literal">
MyISAM

table has no free blocks in the middle of the data file, rows
are always inserted at the end of the data file. In this case,
you can freely mix concurrent
<a class="link" href="insert.html" title="15.2.7 INSERT Statement">
<code class="literal">
INSERT
</code>
</a>
and
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT

</a>
statements for a
<code class="literal">
MyISAM
</code>
table without locks. That is, you
can insert rows into a
<code class="literal">
MyISAM
</code>
table at the
same time other clients are reading from it. Holes can result
from rows having been deleted from or updated in the middle of
the table. If there are holes, concurrent inserts are disabled
but are enabled again automatically when all holes have been
filled with new data. To control this behavior, use the
<a class="link" href="server-system-variables.html#sysvar_concurrent_insert">
<code class="literal">

As a popular, open-source software, MySQL, in its original or

sources, including different software download sites, software
repositories, and so on. The following instructions assume that
MySQL is not already installed on your system using a
third-party-distributed RPM package; if that is not the case,
follow the instructions given at

2.9.3 Testing the Server
</h3>
</div>
</div>
</div>
<p>
After the data directory is initialized and you have started the
server, perform some simple tests to make sure that it works
satisfactorily. This section assumes that your current location is
the MySQL installation directory and that it has a
<code class="filename">
bin
</code>
subdirectory containing the MySQL
programs used here. If that is not true, adjust the command path
names accordingly.
</p>
<a class="indexterm" name="idm46045326753360">
</a>
<a class="indexterm" name="idm46045326752272">
</a>
<p>
Alternatively, add the
<code class="filename">
bin
</code>
directory to your
<code class="literal">
PATH
</code>
environment variable setting. That enables
your shell (command interpreter) to find MySQL programs properly,
so that you can run a program by typing only its name, not its
path name. See
<a class="xref" href="setting-environment-variables.html" title="6.2.9 Setting Environment Variables">
Section 6.2.9, “Setting Environment Variables”
</a>
.
</p>
<p>
Use
<a class="link" href="mysqladmin.html" title="6.5.2 mysqladmin — A MySQL Server Administration Program">
<span class="command">
<strong>
mysqladmin
</strong>
</span>
</a>
to verify that the server is
running. The following commands provide simple tests to check
whether the server is up and responding to connections:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-terminal"><div class="docs-select-all right" id="sa51889759"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal"><span class="token prompt">$> </span><span class="token command">bin/mysqladmin</span> version
<span class="token prompt">$> </span><span class="token command">bin/mysqladmin</span> variables</code></pre>
</div>
<p>
If you cannot connect to the server, specify a
<code class="option">
-u
root
</code>
option to connect as
<code class="literal">
root
</code>
. If you
have assigned a password for the
<code class="literal">
root
</code>
account
already, you'll also need to specify
<code class="option">
-p
</code>
on the
command line and enter the password when prompted. For example:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-terminal"><div class="docs-select-all right" id="sa15515748"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal"><span class="token prompt">$> </span><span class="token command">bin/mysqladmin</span> <span class="token property">-u</span> root <span class="token property">-p</span> version

12.16 MySQL Server Locale Support
</h2>

</div>
<p>
The locale indicated by the
<a class="link" href="server-system-variables.html#sysvar_lc_time_names">
<code class="literal">
lc_time_names
</code>
</a>
system variable
controls the language used to display day and month names and
abbreviations. This variable affects the output from the
<a class="link" href="date-and-time-functions.html#function_date-format">
<code class="literal">
DATE_FORMAT()
</code>
</a>
,
<a class="link" href="date-and-time-functions.html#function_dayname">
<code class="literal">
DAYNAME()
</code>
</a>
, and
<a class="link" href="date-and-time-functions.html#function_monthname">
<code class="literal">
MONTHNAME()
</code>
</a>
functions.
</p>
<p>
<a class="link" href="server-system-variables.html#sysvar_lc_time_names">
<code class="literal">
lc_time_names
</code>
</a>
does not affect the
<a class="link" href="date-and-time-functions.html#function_str-to-date">
<code class="literal">
STR_TO_DATE()
</code>
</a>
or
<a class="link" href="date-and-time-functions.html#function_get-format">
<code class="literal">
GET_FORMAT()
</code>
</a>
function.
</p>
<p>
The
<a class="link" href="server-system-variables.html#sysvar_lc_time_names">
<code class="literal">
lc_time_names
</code>
</a>
value does not
affect the result from
<a class="link" href="string-functions.html#function_format">
<code class="literal">
FORMAT()
</code>
</a>
,
but this function takes an optional third parameter that enables a
locale to be specified to be used for the result number's decimal
point, thousands separator, and grouping between separators.
Permissible locale values are the same as the legal values for the
<a class="link" href="server-system-variables.html#sysvar_lc_time_names">
<code class="literal">
lc_time_names
</code>
</a>
system variable.
</p>
<p>
Locale names have language and region subtags listed by IANA
(
<a class="ulink" href="http://www.iana.org/assignments/language-subtag-registry" target="_blank">
http://www.iana.org/assignments/language-subtag-registry
</a>
)
such as
<code class="literal">
'ja_JP'
</code>
or
<code class="literal">
'pt_BR'
</code>
.
The default value is
<code class="literal">
'en_US'
</code>
regardless of your
system's locale setting, but you can set the value at server
startup, or set the
<code class="literal">
GLOBAL
</code>
value at runtime if
you have privileges sufficient to set global system variables; see
<a class="xref" href="system-variable-privileges.html" title="7.1.9.1 System Variable Privileges">
Section 7.1.9.1, “System Variable Privileges”
</a>
. Any client can
examine the value of
<a class="link" href="server-system-variables.html#sysvar_lc_time_names">
<code class="literal">
lc_time_names
</code>
</a>
or set its
<code class="literal">
SESSION
</code>
value to affect the locale for its own
connection.
</p>
<p>
(The first
<a class="link" href="set-names.html" title="15.7.6.3 SET NAMES Statement">
<code class="literal">
SET NAMES
</code>
</a>
statement in
the following example may not be necessary if no settings relating
to character set and collation have been changed from their
defaults; we include it for completeness.)

17.6.4 Doublewrite Buffer
</h3>
</div>
</div>
</div>
<p>
The doublewrite buffer is a storage area where
<code class="literal">
InnoDB
</code>
writes pages flushed from the buffer
pool before writing the pages to their proper positions in the
<code class="literal">
InnoDB
</code>
data files. If there is an operating
system, storage subsystem, or unexpected
<a class="link" href="mysqld.html" title="6.3.1 mysqld — The MySQL Server">
<span class="command">
<strong>
mysqld
</strong>
</span>
</a>
process exit in the middle of a page write,
<code class="literal">
InnoDB
</code>
can find a good copy of the page from
the doublewrite buffer during crash recovery.
</p>
<p>
Although data is written twice, the doublewrite buffer does not
require twice as much I/O overhead or twice as many I/O
operations. Data is written to the doublewrite buffer in a large
sequential chunk, with a single
<code class="literal">
fsync()
</code>
call to
the operating system (except in the case that
<a class="link" href="innodb-parameters.html#sysvar_innodb_flush_method">
<code class="literal">
innodb_flush_method
</code>
</a>
is set to
<code class="literal">
O_DIRECT_NO_FSYNC
</code>
).
</p>
<p>
The doublewrite buffer storage area is located in doublewrite
files.
</p>
<p>
The following variables are provided for doublewrite buffer
configuration:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite">
<code class="literal">
innodb_doublewrite
</code>
</a>
</p>
<p>
The
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite">
<code class="literal">
innodb_doublewrite
</code>
</a>
variable controls whether the doublewrite buffer is enabled.
It is enabled by default in most cases. To disable the
doublewrite buffer, set
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite">
<code class="literal">
innodb_doublewrite
</code>
</a>
to
<code class="literal">
OFF
</code>
. Consider disabling the doublewrite
buffer if you are more concerned with performance than data
integrity, as may be the case when performing benchmarks, for
example.
</p>
<p>
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite">
<code class="literal">
innodb_doublewrite
</code>
</a>
supports
<code class="literal">
DETECT_AND_RECOVER
</code>
and
<code class="literal">
DETECT_ONLY
</code>
settings.
</p>
<p>
The
<code class="literal">
DETECT_AND_RECOVER
</code>
setting is the same
as the
<code class="literal">
ON
</code>
setting. With this setting, the
doublewrite buffer is fully enabled, with database page
content written to the doublewrite buffer where it is accessed
during recovery to fix incomplete page writes.
</p>
<p>
With the
<code class="literal">
DETECT_ONLY
</code>
setting, only metadata
is written to the doublewrite buffer. Database page content is
not written to the doublewrite buffer, and recovery does not
use the doublewrite buffer to fix incomplete page writes. This
lightweight setting is intended for detecting incomplete page
writes only.
</p>
<p>
MySQL supports dynamic changes to the
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite">
<code class="literal">
innodb_doublewrite
</code>
</a>
setting
that enables the doublewrite buffer, between
<code class="literal">
ON
</code>
,
<code class="literal">
DETECT_AND_RECOVER
</code>
,
and
<code class="literal">
DETECT_ONLY
</code>
. MySQL does not support
dynamic changes between a setting that enables the doublewrite
buffer and
<code class="literal">
OFF
</code>
or vice versa.
</p>
<p>
If the doublewrite buffer is located on a Fusion-io device
that supports atomic writes, the doublewrite buffer is
automatically disabled and data file writes are performed
using Fusion-io atomic writes instead. However, be aware that
the
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite">
<code class="literal">
innodb_doublewrite
</code>
</a>
setting is global. When the doublewrite buffer is disabled, it
is disabled for all data files including those that do not
reside on Fusion-io hardware. This feature is only supported
on Fusion-io hardware and is only enabled for Fusion-io NVMFS
on Linux. To take full advantage of this feature, an
<a class="link" href="innodb-parameters.html#sysvar_innodb_flush_method">
<code class="literal">
innodb_flush_method
</code>
</a>
setting
of
<code class="literal">
O_DIRECT
</code>
is recommended.
</p>
</li>
<li class="listitem">
<p>
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite_dir">
<code class="literal">
innodb_doublewrite_dir
</code>
</a>
</p>
<p>
The
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite_dir">
<code class="literal">
innodb_doublewrite_dir
</code>
</a>
variable defines the directory where
<code class="literal">
InnoDB
</code>
creates doublewrite files. If no directory is specified,
doublewrite files are created in the
<a class="link" href="innodb-parameters.html#sysvar_innodb_data_home_dir">
<code class="literal">
innodb_data_home_dir
</code>
</a>
directory, which defaults to the data directory if
unspecified.
</p>
<p>
A hash symbol '#' is automatically prefixed to the specified
directory name to avoid conflicts with schema names. However,
if a '.', '#'. or '/' prefix is specified explicitly in the
directory name, the hash symbol '#' is not prefixed to the
directory name.
</p>
<p>
Ideally, the doublewrite directory should be placed on the
fastest storage media available.

<p>
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite_files">
<code class="literal">

</a>
</p>
<p>
The
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite_files">
<code class="literal">
innodb_doublewrite_files
</code>
</a>
variable defines the number of doublewrite files, which
defaults to 2. By default, two doublewrite files are created
for each buffer pool instance: A flush list doublewrite file
and an LRU list doublewrite file.
</p>
<p>
The flush list doublewrite file is for pages flushed from the
buffer pool flush list. The default size of a flush list
doublewrite file is the
<code class="literal">
InnoDB
</code>
page size *
doublewrite page bytes.
</p>
<p>
The LRU list doublewrite file is for pages flushed from the
buffer pool LRU list. It also contains slots for single page
flushes. The default size of an LRU list doublewrite file is
the
<code class="literal">
InnoDB
</code>
page size * (doublewrite pages +
(512 / the number of buffer pool instances)) where 512 is the
total number of slots reserved for single page flushes.
</p>
<p>
At a minimum, there are two doublewrite files. The maximum
number of doublewrite files is two times the number of buffer
pool instances. (The number of buffer pool instances is
controlled by the
<a class="link" href="innodb-parameters.html#sysvar_innodb_buffer_pool_instances">
<code class="literal">
innodb_buffer_pool_instances
</code>
</a>
variable.)
</p>
<p>
Doublewrite file names have the following format:
<code class="filename">
#ib_
<em class="replaceable">
<code>
page_size
</code>
</em>
_
<em class="replaceable">
<code>
file_number
</code>
</em>
.dblwr
</code>
(or
<code class="filename">
.bdblwr
</code>
with the
<code class="literal">
DETECT_ONLY
</code>
setting). For example, the
following doublewrite files are created for a MySQL instance
with an
<code class="literal">
InnoDB
</code>
pages size of 16KB and a
single buffer pool:

<p>
The
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite_files">
<code class="literal">
innodb_doublewrite_files

variable is intended for advanced performance tuning. The

<p>
The
<a class="link" href="innodb-parameters.html#sysvar_innodb_doublewrite_pages">
<code class="literal">
innodb_doublewrite_pages
</code>
</a>
variable controls the maximum number of doublewrite pages per
thread. This variable is intended for advanced performance
tuning. The default value should be suitable for most users.
</p>
</li>
</ul>
</div>
<p>
<code class="literal">
InnoDB
</code>
automatically encrypts doublewrite file
pages that belong to encrypted tablespaces (see
<a class="xref" href="innodb-data-encryption.html" title="17.13 InnoDB Data-at-Rest Encryption">
Section 17.13, “InnoDB Data-at-Rest Encryption”
</a>
). Likewise, doublewrite
file pages belonging to page-compressed tablespaces are
compressed. As a result, doublewrite files can contain different
page types including unencrypted and uncompressed pages, encrypted
pages, compressed pages, and pages that are both encrypted and
compressed.

15.6.7.7 The MySQL Diagnostics Area
</h4>
</div>
</div>
</div>
<p>
SQL statements produce diagnostic information that populates the
diagnostics area. Standard SQL has a diagnostics area stack,
containing a diagnostics area for each nested execution context.
Standard SQL also supports
<a class="link" href="get-diagnostics.html" title="15.6.7.3 GET DIAGNOSTICS Statement">
<code class="literal">

</a>
syntax for referring to the second
diagnostics area during condition handler execution.

The following discussion describes the structure of the
diagnostics area in MySQL, the information items recognized by
MySQL, how statements clear and set the diagnostics area, and
how diagnostics areas are pushed to and popped from the stack.

The diagnostics area contains two kinds of information:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Statement information, such as the number of conditions

</p>
</li>
<li class="listitem">
<p>
Condition information, such as the error code and message.
If a statement raises multiple conditions, this part of
the diagnostics area has a condition area for each one. If
a statement raises no conditions, this part of the
diagnostics area is empty.
</p>
</li>
</ul>
</div>
<p>
For a statement that produces three conditions, the
diagnostics area contains statement and condition information
like this:

The condition information part of the diagnostics area
contains a condition area for each condition. Condition areas
are numbered from 1 to the value of the
<code class="literal">
NUMBER
</code>
statement condition item. If
<code class="literal">
NUMBER
</code>
is 0, there are no condition areas.
</p>
<p>
Each condition area contains the items in the following list.
All items are standard SQL except
<code class="literal">
MYSQL_ERRNO
</code>
, which is a MySQL extension.
The definitions apply for conditions generated other than by a
signal (that is, by a
<a class="link" href="signal.html" title="15.6.7.5 SIGNAL Statement">
<code class="literal">
SIGNAL
</code>
</a>
or
<a class="link" href="resignal.html" title="15.6.7.4 RESIGNAL Statement">
<code class="literal">

</code>
</a>
statement). For
nonsignal conditions, MySQL populates only those condition
items not described as always empty. The effects of signals on
the condition area are described later.

Nondiagnostic SQL statements populate the diagnostics area
automatically, and its contents can be set explicitly with the
<a class="link" href="signal.html" title="15.6.7.5 SIGNAL Statement">

</a>
and
<a class="link" href="resignal.html" title="15.6.7.4 RESIGNAL Statement">
<code class="literal">

statements. The
diagnostics area can be examined with
<a class="link" href="get-diagnostics.html" title="15.6.7.3 GET DIAGNOSTICS Statement">
<code class="literal">
GET

or
<a class="link" href="show-errors.html" title="15.7.7.18 SHOW ERRORS Statement">
<code class="literal">
SHOW ERRORS

</a>
to see conditions
or errors.
</p>
<p>
SQL statements clear and set the diagnostics area as follows:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
When the server starts executing a statement after parsing
it, it clears the diagnostics area for nondiagnostic
statements. Diagnostic statements do not clear the
diagnostics area. These statements are diagnostic:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: circle; ">
<li class="listitem">
<p>
<a class="link" href="get-diagnostics.html" title="15.6.7.3 GET DIAGNOSTICS Statement">
<code class="literal">
GET DIAGNOSTICS
</code>
</a>

</li>
<li class="listitem">
<p>
<a class="link" href="show-errors.html" title="15.7.7.18 SHOW ERRORS Statement">
<code class="literal">

</code>
</a>
</p>
</li>
<li class="listitem">
<p>
<a class="link" href="show-warnings.html" title="15.7.7.42 SHOW WARNINGS Statement">
<code class="literal">
SHOW WARNINGS
</code>
</a>
</p>
</li>
</ul>
</div>
</li>
<li class="listitem">
<p>
If a statement raises a condition, the diagnostics area is
cleared of conditions that belong to earlier statements.
The exception is that conditions raised by
<a class="link" href="get-diagnostics.html" title="15.6.7.3 GET DIAGNOSTICS Statement">
<code class="literal">
GET DIAGNOSTICS
</code>
</a>
and
<a class="link" href="resignal.html" title="15.6.7.4 RESIGNAL Statement">
<code class="literal">
RESIGNAL
</code>
</a>
are added to the
diagnostics area without clearing it.
</p>
</li>
</ul>
</div>
<p>
Thus, even a statement that does not normally clear the
diagnostics area when it begins executing clears it if the
statement raises a condition.

The following example shows the effect of various statements
on the diagnostics area, using
<a class="link" href="show-warnings.html" title="15.7.7.42 SHOW WARNINGS Statement">

How the Diagnostics Area Stack Works
</h5>
</div>
</div>
</div>
<p>
When a push to the diagnostics area stack occurs, the first
(current) diagnostics area becomes the second (stacked)
diagnostics area and a new current diagnostics area is created
as a copy of it. Diagnostics areas are pushed to and popped
from the stack under the following circumstances:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Execution of a stored program
</p>
<p>
A push occurs before the program executes and a pop occurs
afterward. If the stored program ends while handlers are
executing, there can be more than one diagnostics area to
pop; this occurs due to an exception for which there are
no appropriate handlers or due to
<a class="link" href="return.html" title="15.6.5.7 RETURN Statement">
<code class="literal">
RETURN
</code>
</a>
in the handler.
</p>
<p>
Any warning or error conditions in the popped diagnostics
areas then are added to the current diagnostics area,
except that, for triggers, only errors are added. When the
stored program ends, the caller sees these conditions in
its current diagnostics area.
</p>
</li>
<li class="listitem">
<p>
Execution of a condition handler within a stored program
</p>
<p>
When a push occurs as a result of condition handler
activation, the stacked diagnostics area is the area that
was current within the stored program prior to the push.
The new now-current diagnostics area is the handler's
current diagnostics area.
<a class="link" href="get-diagnostics.html" title="15.6.7.3 GET DIAGNOSTICS Statement">
<code class="literal">

[CURRENT] DIAGNOSTICS

and
<a class="link" href="get-diagnostics.html" title="15.6.7.3 GET DIAGNOSTICS Statement">
<code class="literal">
GET
STACKED DIAGNOSTICS
</code>
</a>
can be used within the
handler to access the contents of the current (handler)
and stacked (stored program) diagnostics areas. Initially,
they return the same result, but statements executing
within the handler modify the current diagnostics area,
clearing and setting its contents according to the normal
rules (see
<a class="xref" href="diagnostics-area.html#diagnostics-area-populating" title="How the Diagnostics Area is Cleared and Populated">
How the Diagnostics Area is Cleared and Populated
</a>
).
The stacked diagnostics area cannot be modified by
statements executing within the handler except
<a class="link" href="resignal.html" title="15.6.7.4 RESIGNAL Statement">
<code class="literal">
RESIGNAL
</code>
</a>
.
</p>
<p>
If the handler executes successfully, the current
(handler) diagnostics area is popped and the stacked
(stored program) diagnostics area again becomes the
current diagnostics area. Conditions added to the handler
diagnostics area during handler execution are added to the
current diagnostics area.

Diagnostics Area-Related System Variables

Certain system variables control or are related to some

<li class="listitem">
<p>
<a class="link" href="server-system-variables.html#sysvar_max_error_count">
<code class="literal">
max_error_count
</code>
</a>
controls
the number of condition areas in the diagnostics area. If
more conditions than this occur, MySQL silently discards
information for the excess conditions. (Conditions added
by
<a class="link" href="resignal.html" title="15.6.7.4 RESIGNAL Statement">
<code class="literal">
RESIGNAL
</code>
</a>
are always
added, with older conditions being discarded as necessary
to make room.)
</p>
</li>
<li class="listitem">
<p>
<a class="link" href="server-system-variables.html#sysvar_warning_count">
<code class="literal">
warning_count
</code>
</a>
indicates
the number of conditions that occurred. This includes
errors, warnings, and notes. Normally,
<code class="literal">
NUMBER
</code>
and
<a class="link" href="server-system-variables.html#sysvar_warning_count">
<code class="literal">
warning_count
</code>
</a>
are the

exceeds
<a class="link" href="server-system-variables.html#sysvar_max_error_count">
<code class="literal">
max_error_count
</code>
</a>
,
the value of
<a class="link" href="server-system-variables.html#sysvar_warning_count">
<code class="literal">
warning_count

</a>
continues
to rise whereas
<code class="literal">
NUMBER
</code>
remains capped
at
<a class="link" href="server-system-variables.html#sysvar_max_error_count">
<code class="literal">
max_error_count
</code>
</a>
because no additional conditions are stored in the
diagnostics area.

<li class="listitem">
<p>
<a class="link" href="server-system-variables.html#sysvar_error_count">
<code class="literal">

indicates the
number of errors that occurred. This value includes
<span class="quote">
“
<span class="quote">

”
</span>
and exception conditions, but
excludes warnings and notes. Like
<a class="link" href="server-system-variables.html#sysvar_warning_count">
<code class="literal">
warning_count

</a>
, its value
can exceed
<a class="link" href="server-system-variables.html#sysvar_max_error_count">

Example: If

<code class="literal">
max_error_count
</code>
</a>
is 10, the diagnostics area can contain a maximum of 10
condition areas. Suppose that a statement raises 20
conditions, 12 of which are errors. In that case, the
diagnostics area contains the first 10 conditions,
<code class="literal">
NUMBER
</code>
is 10,
<a class="link" href="server-system-variables.html#sysvar_warning_count">
<code class="literal">
warning_count
</code>
</a>
is 20, and
<a class="link" href="server-system-variables.html#sysvar_error_count">
<code class="literal">
error_count

</a>
is 12.
</p>
<p>
Changes to the value of
<a class="link" href="server-system-variables.html#sysvar_max_error_count">
<code class="literal">
max_error_count

</a>
have no
effect until the next attempt to modify the diagnostics area.
If the diagnostics area contains 10 condition areas and
<a class="link" href="server-system-variables.html#sysvar_max_error_count">
<code class="literal">
max_error_count
</code>
</a>
is set to 5,
that has no immediate effect on the size or content of the
diagnostics area.

You can separate a value from the search condition by using
the
<code class="literal">
bind()
</code>
method. For example, instead of
using "Name = 'Z%' " as the condition, substitute a named
placeholder consisting of a colon followed by a name that
begins with a letter, such as
<span class="emphasis">
<em>
name
</em>
</span>
. Then
include the placeholder and value in the
<code class="literal">
bind()

method as follows:

<p>
Within a program, binding enables you to specify
placeholders in your expressions, which are filled in with
values before execution and can benefit from automatic
escaping, as appropriate.
</p>
<p>
Always use binding to sanitize input. Avoid introducing
values in queries using string concatenation, which can
produce invalid input and, in some cases, can cause security
issues.

no member has a special role. Any member that is compatible with
the other group members is set to read/write mode when joining
the group, and can process write transactions, even if they are
issued concurrently.
</p>
<p>
If a member stops accepting write transactions, for example, in
the event of an unexpected server exit, clients connected to it
can be redirected, or failed over, to any other member that is
in read/write mode. Group Replication does not handle
client-side failover itself, so you need to arrange this using a
middleware framework such as
<a class="ulink" href="/doc/mysql-router/8.4/en/" target="_top">
MySQL Router 8.4

, a
proxy, a connector, or the application itself.

Group Replication is an eventual consistency system. This means
that as soon as the incoming traffic slows down or stops, all
group members have the same data content. While traffic is
flowing, transactions can be externalized on some members before
the others, especially if some members have less write
throughput than others, creating the possibility of stale reads.
In multi-primary mode, slower members can also build up an
excessive backlog of transactions to certify and apply, leading
to a greater risk of conflicts and certification failure. To
limit these issues, you can activate and tune Group
Replication's flow control mechanism to minimize the difference
between fast and slow members. For more information on flow
control, see
<a class="xref" href="group-replication-flow-control.html" title="20.7.2 Flow Control">

If you want transaction consistency guaranteed for every
transaction in the group, you can do this using the
<a class="link" href="group-replication-system-variables.html#sysvar_group_replication_consistency">
<code class="literal">
group_replication_consistency
</code>
</a>
system variable. You can choose a setting that suits the
workload of your group and your priorities for data reads and
writes, taking into account the performance impact of the
synchronization required to increase consistency. You can also
set the system variable for individual sessions to protect
particularly concurrency-sensitive transactions. For more
information on transaction consistency, see

20.1.3.2.1 Transaction Checks
</h5>
</div>
</div>
</div>
<p>
When a group is deployed in multi-primary mode, transactions
are checked to ensure they are compatible with the mode. The
following strict consistency checks are made when Group
Replication is deployed in multi-primary mode:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
If a transaction is executed under the SERIALIZABLE
isolation level, then its commit fails when synchronizing
itself with the group.
</p>
</li>
<li class="listitem">
<p>
If a transaction executes against a table that has foreign
keys with cascading constraints, then its commit fails
when synchronizing itself with the group.
</p>
</li>
</ul>
</div>
<p>
The checks are controlled by the
<a class="link" href="group-replication-system-variables.html#sysvar_group_replication_enforce_update_everywhere_checks">
<code class="literal">
group_replication_enforce_update_everywhere_checks
</code>
</a>
system variable. In multi-primary mode, the system variable
should normally be set to
<code class="literal">
ON
</code>
, but the
checks can optionally be deactivated by setting the system
variable to
<code class="literal">
OFF
</code>
. When deploying in
single-primary mode, the system variable must be set to

20.1.3.2.2 Data Definition Statements
</h5>
</div>
</div>
</div>
<a class="indexterm" name="idm46045134412416">
</a>
<p>
In a Group Replication topology in multi-primary mode, care
needs to be taken when executing data definition statements,
also commonly known as data definition language (DDL).
</p>
<p>
MySQL 8.4 supports atomic Data Definition
Language (DDL) statements, where the complete DDL statement is
either committed or rolled back as a single atomic
transaction. DDL statements, atomic or otherwise, implicitly
end any transaction that is active in the current session, as
if you had done a
<a class="link" href="commit.html" title="15.3.1 START TRANSACTION, COMMIT, and ROLLBACK Statements">
<code class="literal">
COMMIT
</code>
</a>
before
executing the statement. This means that DDL statements cannot
be performed within another transaction, within transaction
control statements such as
<a class="link" href="commit.html" title="15.3.1 START TRANSACTION, COMMIT, and ROLLBACK Statements">
<code class="literal">
START TRANSACTION ...
COMMIT
</code>
</a>
, or combined with other statements within the
same transaction.
</p>
<p>
Group Replication is based on an optimistic replication
paradigm, where statements are optimistically executed and
rolled back later if necessary. Each server executes without
securing group agreement first. Therefore, more care needs to
be taken when replicating DDL statements in multi-primary
mode. If you make schema changes (using DDL) and changes to
the data that an object contains (using DML) for the same
object, the changes need to be handled through the same server
while the schema operation has not yet completed and
replicated everywhere. Failure to do so can result in data
inconsistency when operations are interrupted or only
partially completed. If the group is deployed in
single-primary mode this issue does not occur, because all
changes are performed through the same server, the primary.
</p>
<p>

20.1.3.2.3 Version Compatibility
</h5>
</div>
</div>
</div>
<p>
For optimal compatibility and performance, all members of a
group should run the same version of MySQL Server and
therefore of Group Replication. In multi-primary mode, this is
more significant because all members would normally join the
group in read/write mode. If a group includes members running
more than one MySQL Server version, there is a potential for
some members to be incompatible with others, because they
support functions others do not, or lack functions others
have. To guard against this, when a new member joins
(including a former member that has been upgraded and
restarted), the member carries out compatibility checks
against the rest of the group.
</p>
<p>
One result of these compatibility checks is particularly
important in multi-primary mode. If a joining member is
running a higher MySQL Server version than the lowest version
that the existing group members are running, it joins the
group but remains in read-only mode. (In a group that is
running in single-primary mode, new members default to
read-only in any case.) Members take into account the
major.minor.release version of the MySQL software (and thus,
of the Group Replication plugin) when checking their
compatibility.
</p>
<p>
In a group running in multi-primary mode with members that use
different MySQL Server versions, Group Replication
automatically manages their read/write and read-only status.
If a member leaves the group, the members running the version
that is now the lowest are automatically set to read/write
mode. When you change a group that was running in
single-primary mode to run in multi-primary mode, using the
function
<a class="link" href="group-replication-functions-for-mode.html#function_group-replication-switch-to-multi-primary-mode">
<code class="literal">
group_replication_switch_to_multi_primary_mode()
</code>
</a>
,
Group Replication automatically sets members to the correct
mode. Members are automatically placed in read-only mode if
they are running a higher MySQL server version than the lowest
version present in the group, and members running the lowest
version are placed in read/write mode.
</p>
<p>

how this influences the behavior of a group during an upgrade
process, see

B.3.4.8 Problems with Floating-Point Values
</h4>
</div>
</div>
</div>
<p>
Floating-point numbers sometimes cause confusion because they
are approximate and not stored as exact values. A
floating-point value as written in an SQL statement may not be
the same as the value represented internally. Attempts to
treat floating-point values as exact in comparisons may lead
to problems. They are also subject to platform or
implementation dependencies. The
<a class="link" href="floating-point-types.html" title="13.1.4 Floating-Point Types (Approximate Value) - FLOAT, DOUBLE">
<code class="literal">
FLOAT
</code>
</a>
and
<a class="link" href="floating-point-types.html" title="13.1.4 Floating-Point Types (Approximate Value) - FLOAT, DOUBLE">
<code class="literal">
DOUBLE
</code>
</a>
data types are subject
to these issues. For
<a class="link" href="fixed-point-types.html" title="13.1.3 Fixed-Point Types (Exact Value) - DECIMAL, NUMERIC">
<code class="literal">
DECIMAL
</code>
</a>
columns, MySQL performs operations with a precision of 65
decimal digits, which should solve most common inaccuracy
problems.
</p>
<p>
The following example uses
<a class="link" href="floating-point-types.html" title="13.1.4 Floating-Point Types (Approximate Value) - FLOAT, DOUBLE">
<code class="literal">
DOUBLE
</code>
</a>
to demonstrate how
calculations that are done using floating-point operations are
subject to floating-point error.

The result is correct. Although the first five records look
like they should not satisfy the comparison (the values of
<code class="literal">
a
</code>
and
<code class="literal">
b
</code>
do not appear to
be different), they may do so because the difference between
the numbers shows up around the tenth decimal or so, depending
on factors such as computer architecture or the compiler
version or optimization level. For example, different CPUs may
evaluate floating-point numbers differently.

<p>
The correct way to do floating-point number comparison is to
first decide on an acceptable tolerance for differences
between the numbers and then do the comparison against the
tolerance value. For example, if we agree that floating-point
numbers should be regarded the same if they are same within a
precision of one in ten thousand (0.0001), the comparison
should be written to find differences larger than the
tolerance value:

An implication of the preceding issues is that if you attempt

MySQL supports views, including updatable views. Views are stored
queries that when invoked produce a result set. A view acts as a
virtual table.
</p>
<p>
The following discussion describes the syntax for creating and
dropping views, and shows some examples of how to use them.

<p>
The stopword list is loaded and searched for full-text queries
using the server character set and collation (the values of the
<a class="link" href="server-system-variables.html#sysvar_character_set_server">
<code class="literal">
character_set_server
</code>
</a>
and
<a class="link" href="server-system-variables.html#sysvar_collation_server">
<code class="literal">

</a>
system
variables). False hits or misses might occur for stopword
lookups if the stopword file or columns used for full-text
indexing or searches have a character set or collation different
from
<a class="link" href="server-system-variables.html#sysvar_character_set_server">
<code class="literal">
character_set_server
</code>
</a>
or
<a class="link" href="server-system-variables.html#sysvar_collation_server">
<code class="literal">
collation_server
</code>
</a>
.
</p>
<p>
Case sensitivity of stopword lookups depends on the server
collation. For example, lookups are case-insensitive if the
collation is
<code class="literal">
utf8mb4_0900_ai_ci
</code>
, whereas
lookups are case-sensitive if the collation is
<code class="literal">
utf8mb4_0900_as_cs
</code>
or
<code class="literal">
utf8mb4_bin

has a relatively short list of
default stopwords, because documents from technical, literary,

significant phrases. For example, you might search for
<span class="quote">
“
<span class="quote">
to be or not to be

</span>
and expect to get a sensible
result, rather than having all those words ignored.

<a class="link" href="innodb-parameters.html#sysvar_innodb_ft_user_stopword_table">
<code class="literal">

To override the default stopword list for MyISAM tables, set
the
<a class="link" href="server-system-variables.html#sysvar_ft_stopword_file">
<code class="literal">

</a>
system
variable. (See
<a class="xref" href="server-system-variables.html" title="7.1.8 Server System Variables">
Section 7.1.8, “Server System Variables”
</a>
.) The
variable value should be the path name of the file containing
the stopword list, or the empty string to disable stopword
filtering. The server looks for the file in the data directory
unless an absolute path name is given to specify a different
directory. After changing the value of this variable or the
contents of the stopword file, restart the server and rebuild
your
<code class="literal">
FULLTEXT
</code>
indexes.
</p>
<p>
The stopword list is free-form, separating stopwords with any
nonalphanumeric character such as newline, space, or comma.
Exceptions are the underscore character (
<code class="literal">
_
</code>
)
and a single apostrophe (
<code class="literal">
'
</code>
) which are
treated as part of a word. The character set of the stopword
list is the server's default character set; see

Section 12.3.2, “Server Character Set and Collation”
</a>

<p>
The following list shows the default stopwords for
<code class="literal">
MyISAM

search indexes. In a MySQL source
distribution, you can find this list in the

Kerberos pluggable authentication is an extension included in
MySQL Enterprise Edition, a commercial product. To learn more about commercial
products, see
<a class="ulink" href="https://www.mysql.com/products/" target="_blank">
https://www.mysql.com/products/
</a>
.
</p>
</div>
<p>
MySQL Enterprise Edition supports an authentication method that enables users to
authenticate to MySQL Server using Kerberos, provided that
appropriate Kerberos tickets are available or can be obtained.
</p>
<p>
This authentication method is available in MySQL
8.4 for MySQL servers and clients on Linux. It is
useful in Linux environments where applications have access to
Microsoft Active Directory, which has Kerberos enabled by
default. The client-side plugin is supported on Windows as well.
The server-side plugin is still supported only on Linux.
</p>
<p>
Kerberos pluggable authentication provides these capabilities:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
External authentication: Kerberos authentication enables
MySQL Server to accept connections from users defined
outside the MySQL grant tables who have obtained the proper
Kerberos tickets.
</p>
</li>
<li class="listitem">
<p>
Security: Kerberos uses tickets together with symmetric-key
cryptography, enabling authentication without sending
passwords over the network. Kerberos authentication supports
userless and passwordless scenarios.
</p>
</li>
</ul>
</div>
<p>
The following table shows the plugin and library file names. The
file name suffix might differ on your system. The file must be
located in the directory named by the
<a class="link" href="server-system-variables.html#sysvar_plugin_dir">
<code class="literal">

The server-side Kerberos authentication plugin is included only
in MySQL Enterprise Edition. It is not included in MySQL community distributions.
The client-side plugin is included in all distributions,
including community distributions. This enables clients from any
distribution to connect to a server that has the server-side
plugin loaded.

Authentication using Kerberos requires a KDC server, for
example, as provided by Microsoft Active Directory.
</p>
<p>
Kerberos authentication in MySQL uses Generic Security Service
Application Program Interface (GSSAPI), which is a security
abstraction interface. Kerberos is an instance of a specific
security protocol that can be used through that abstract
interface. Using GSSAPI, applications authenticate to Kerberos
to obtain service credentials, then use those credentials in
turn to enable secure access to other services.
</p>
<p>
On Windows, the
<code class="literal">
authentication_kerberos_client
</code>
authentication plugin supports two modes, which the client
user can set at runtime or specify in an option file:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<code class="literal">

mode: Security Support Provider
Interface (SSPI) implements GSSAPI (see
<a class="link" href="kerberos-pluggable-authentication.html#kerberos-usage-win-sspi-client-commands">
Commands for Windows Clients in SSPI Mode
</a>
). SSPI,
while being compatible with GSSAPI at the wire level, only
supports the Windows single sign-on scenario and
specifically refers to the logged-on user. SSPI is the
default mode on most Windows clients.
</p>
</li>
<li class="listitem">

the MIT Kerberos library on Windows (see
<a class="link" href="kerberos-pluggable-authentication.html#kerberos-usage-win-gssapi-client-commands">
Commands for Windows Clients in GSSAPI Mode
</a>
).
</p>
</li>
</ul>
</div>
<p>
With the Kerberos authentication plugins, applications and
MySQL servers are able to use the Kerberos authentication
protocol to mutually authenticate users and MySQL services.
This way both the user and the server are able to verify each
other's identity. No passwords are sent over the network
and Kerberos protocol messages are protected against
eavesdropping and replay attacks.
</p>
<p>
Kerberos authentication follows these steps, where the
server-side and client-side parts are performed using the
<code class="literal">
authentication_kerberos
</code>
and
<code class="literal">
authentication_kerberos_client
</code>
authentication plugins, respectively:
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
The MySQL server sends to the client application its
service principal name. This SPN must be registered in the
Kerberos system, and is configured on the server side
using the
<a class="link" href="pluggable-authentication-system-variables.html#sysvar_authentication_kerberos_service_principal">
<code class="literal">
authentication_kerberos_service_principal
</code>
</a>
system variable.
</p>
</li>
<li class="listitem">
<p>
Using GSSAPI, the client application creates a Kerberos
client-side authentication session and exchanges Kerberos
messages with the Kerberos KDC:

<li class="listitem">

</li>
<li class="listitem">
<p>
Using the TGT, the client obtains a service ticket for
MySQL from the ticket-granting service.
</p>
</li>
</ul>
</div>
<p>
This step can be skipped or partially skipped if the TGT,
ST, or both are already cached locally. The client
optionally may use a client keytab file to obtain a TGT
and ST without supplying a password.

<li class="listitem">
<p>
Using GSSAPI, the client application presents the MySQL ST

</p>
</li>
<li class="listitem">
<p>
Using GSSAPI, the MySQL server creates a Kerberos
server-side authentication session. The server validates
the user identity and the validity of the user request. It
authenticates the ST using the service key configured in
its service keytab file to determine whether
authentication succeeds or fails, and returns the
authentication result to the client.
</p>
</li>
</ol>
</div>
<p>
Applications are able to authenticate using a provided user
name and password, or using a locally cached TGT or ST (for
example, created using
<span class="command">
<strong>
kinit
</strong>
</span>
or similar).
This design therefore covers use cases ranging from completely
userless and passwordless connections, where Kerberos service
tickets are obtained from a locally stored Kerberos cache, to
connections where both user name and password are provided and
used to obtain a valid Kerberos service ticket from a KDC, to
send to the MySQL server.
</p>
<p>
As indicated in the preceding description, MySQL Kerberos
authentication uses two kinds of keytab files:

<div class="itemizedlist">

This section describes how to install the server-side Kerberos
authentication plugin. For general information about
installing plugins, see
<a class="xref" href="plugin-loading.html" title="7.6.1 Installing and Uninstalling Plugins">
Section 7.6.1, “Installing and Uninstalling Plugins”

<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<div class="admon-title">
Note
</div>
<p>
The server-side plugin is supported only on Linux systems.
On Windows systems, only the client-side plugin is
supported, which can be used on a Windows system to connect
to a Linux server that uses Kerberos authentication.
</p>
</div>
<p>
To be usable by the server, the plugin library file must be
located in the MySQL plugin directory (the directory named by
the
<a class="link" href="server-system-variables.html#sysvar_plugin_dir">
<code class="literal">
plugin_dir
</code>
</a>
system
variable). If necessary, configure the plugin directory
location by setting the value of
<a class="link" href="server-system-variables.html#sysvar_plugin_dir">
<code class="literal">
plugin_dir
</code>
</a>
at server startup.
</p>
<p>
The server-side plugin library file base name is
<code class="literal">
authentication_kerberos
</code>
. The file name
suffix for Unix and Unix-like systems is
<code class="filename">
.so
</code>
.
</p>
<p>
To load the plugin at server startup, use the
<a class="link" href="server-options.html#option_mysqld_plugin-load-add">
<code class="option">
--plugin-load-add
</code>
</a>
option to
name the library file that contains it. With this
plugin-loading method, the option must be given each time the
server starts. Also, specify values for any plugin-provided
system variables you wish to configure. The plugin exposes
these system variables, enabling its operation to be
configured:

Section 8.4.1.13, “Pluggable Authentication System Variables”
</a>
.
</p>
<p>
To load the plugin and configure it, put lines such as these
in your
<code class="filename">
my.cnf
</code>
file, using values for the
system variables that are appropriate for your installation:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-ini"><div class="docs-select-all right" id="sa35523648"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-ini"><span class="token selector">[mysqld]</span>

</div>
<p>
After modifying
<code class="filename">
my.cnf
</code>
, restart the
server to cause the new settings to take effect.
</p>
<p>
Alternatively, to load the plugin at runtime, use this
statement:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-sql"><div class="docs-select-all right" id="sa94057788"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">INSTALL</span> <span class="token keyword">PLUGIN</span> authentication_kerberos

</div>
<p>
<a class="link" href="install-plugin.html" title="15.7.4.4 INSTALL PLUGIN Statement">
<code class="literal">
INSTALL PLUGIN
</code>
</a>
loads the plugin
immediately, and also registers it in the
<code class="literal">
mysql.plugins
</code>
system table to cause the
server to load it for each subsequent normal startup without
the need for
<a class="link" href="server-options.html#option_mysqld_plugin-load-add">
<code class="option">
--plugin-load-add
</code>
</a>
.
</p>
<p>
When you install the plugin at runtime without configuring its
system variables in the
<code class="filename">
my.cnf
</code>
file, the
system variable
<a class="link" href="pluggable-authentication-system-variables.html#sysvar_authentication_kerberos_service_key_tab">
<code class="literal">
authentication_kerberos_service_key_tab
</code>
</a>
is set to the default value of
<code class="filename">
mysql.keytab
</code>
in the data directory. The
value of this system variable cannot be changed at runtime, so
if you need to specify a different file, you need to add the
setting to your
<code class="filename">
my.cnf
</code>
file then restart
the MySQL server. For example:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-ini"><div class="docs-select-all right" id="sa1548752"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-ini"><span class="token selector">[mysqld]</span>
<span class="token constant">authentication_kerberos_service_key_tab</span><span class="token attr-value"><span class="token punctuation">=</span>/var/mysql/data/mysql.keytab</span></code></pre>
</div>
<p>
If the keytab file is not in the correct place or does not
contain a valid SPN key, the MySQL server does not validate
this, but clients return authentication errors until you fix
the issue.

The
<a class="link" href="pluggable-authentication-system-variables.html#sysvar_authentication_kerberos_service_principal">

create a MySQL account that corresponds to a Kerberos UPN of
<code class="literal">
<em class="replaceable">
<code>
user
</code>
</em>
@
<em class="replaceable">
<code>
realm_name
</code>
</em>
</code>
,
the MySQL DBA uses a statement like this:
</p>
<div class="copytoclipboard-wrapper">

<span class="token keyword">BY</span> <span class="token string">'<em class="replaceable">realm_name</em>'</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
The account named by
<em class="replaceable">
<code>
user
</code>
</em>
can
include or omit the host name part. If the host name is
omitted, it defaults to
<code class="literal">
%
</code>
as usual. The
<em class="replaceable">
<code>
realm_name
</code>
</em>
is stored as the
<code class="literal">
authentication_string
</code>
value for the account
in the
<code class="literal">
mysql.user
</code>
system table.
</p>
<p>
To create a MySQL account that corresponds to the UPN
<code class="literal">
[email protected]
</code>
, use this statement:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-sql"><div class="docs-select-all right" id="sa83172145"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">CREATE</span> <span class="token keyword">USER</span> <span class="token string">'karl'</span>

</div>
<p>
If MySQL must construct the UPN for this account, for example,
to obtain or validate tickets (TGTs or STs), it does so by
combining the account name (ignoring any host name part) and
the realm name. For example, the full account name resulting
from the preceding
<a class="link" href="create-user.html" title="15.7.1.3 CREATE USER Statement">
<code class="literal">
CREATE USER
</code>
</a>
statement is
<code class="literal">
'karl'@'%'
</code>
. MySQL constructs
the UPN from the user name part
<code class="literal">
karl
</code>
(ignoring the host name part) and the realm name
<code class="literal">
MYSQL.LOCAL
</code>
to produce
<code class="literal">

<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<div class="admon-title">

<p>
Observe that when creating an account that authenticates
using
<code class="literal">
authentication_kerberos
</code>
, the
<a class="link" href="create-user.html" title="15.7.1.3 CREATE USER Statement">
<code class="literal">

</a>
statement does
not include the UPN realm as part of the user name. Instead,
specify the realm (
<code class="literal">
MYSQL.LOCAL
</code>
in this
case) as the authentication string in the
<code class="literal">
BY
</code>
clause. This differs from creating
accounts that use the
<code class="literal">
authentication_ldap_sasl
</code>
SASL LDAP
authentication plugin with the GSSAPI/Kerberos
authentication method. For such accounts, the
<a class="link" href="create-user.html" title="15.7.1.3 CREATE USER Statement">
<code class="literal">
CREATE USER
</code>
</a>
statement does
include the UPN realm as part of the user name. See

Create a MySQL Account That Uses GSSAPI/Kerberos for LDAP Authentication
</a>
.
</p>
</div>
<p>
With the account set up, clients can use it to connect to the
MySQL server. The procedure depends on whether the client host
runs Linux or Windows, as indicated in the following
discussion.
</p>
<p>
Use of
<code class="literal">
authentication_kerberos
</code>
is subject
to the restriction that UPNs with the same user part but a
different realm part are not supported. For example, you
cannot create MySQL accounts that correspond to both these
UPNs:
</p>
<div class="copytoclipboard-wrapper">

kate<span class="token variable">@EXAMPLE.COM</span></code></pre>
</div>
<p>
Both UPNs have a user part of
<code class="literal">
kate
</code>
but
differ in the realm part (
<code class="literal">
MYSQL.LOCAL

versus
<code class="literal">
EXAMPLE.COM

<strong>
Connection
Commands for Linux Clients
</strong>
</span>
</p>
<p>
On Linux, the appropriate client command for connecting to the
MySQL server varies depending on whether the command
authenticates using a TGT from the Kerberos cache, or based on
command options for the MySQL user name and the UPN password:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Prior to invoking the MySQL client program, the client
user can obtain a TGT from the KDC independently of MySQL.
For example, the client user can use
<span class="command">
<strong>
kinit
</strong>
</span>
to authenticate to Kerberos by
providing a Kerberos user principal name and the principal
password:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-terminal"><div class="docs-select-all right" id="sa46768751"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal"><span class="token prompt">$> </span><span class="token command">kinit</span> karl@MYSQL<span class="token punctuation">.</span>LOCAL

</div>
<p>
The resulting TGT for the UPN is cached and becomes
available for use by other Kerberos-aware applications,
such as programs that use the client-side Kerberos
authentication plugin. In this case, invoke the client
without specifying a user-name or password option:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-terminal"><div class="docs-select-all right" id="sa55840832"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal">mysql

<span class="token constant">--plugin-dir</span><span class="token attr-value"><span class="token punctuation">=</span><em class="replaceable">path/to/plugin/directory</em></span></code></pre>
</div>
<p>
The client-side plugin finds the TGT in the cache, uses it
to obtain a MySQL ST, and uses the ST to authenticate to
the MySQL server.
</p>
<p>
As just described, when the TGT for the UPN is cached,
user-name and password options are not needed in the
client command. If the command includes them anyway, they
are handled as follows:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: circle; ">
<li class="listitem">
<p>
This command includes a user-name option:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-terminal"><div class="docs-select-all right" id="sa57899421"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal">mysql

<span class="token constant">--user</span><span class="token attr-value"><span class="token punctuation">=</span>karl</span></code></pre>
</div>
<p>
In this case, authentication fails if the user name
specified by the option does not match the user name
part of the UPN in the TGT.
</p>
</li>
<li class="listitem">
<p>
This command includes a password option, which you
enter when prompted:
</p>
<div class="copytoclipboard-wrapper">

<span class="token property">--password</span></code></pre>
</div>
<p>
In this case, the client-side plugin ignores the
password. Because authentication is based on the TGT,
it can succeed
<span class="emphasis">
<em>
even if the user-provided
password is incorrect
</em>
</span>
. For this reason, the
plugin produces a warning if a valid TGT is found that
causes a password to be ignored.
</p>
</li>
</ul>
</div>

<li class="listitem">
<p>
If the Kerberos cache contains no TGT, the client-side
Kerberos authentication plugin itself can obtain the TGT

the user name (

(

to the MySQL server.
</p>
<p>
Or, suppose that the Kerberos cache contains no TGT and
the command specifies a password option but no user-name
option:

</div>
<p>
The client-side Kerberos authentication plugin uses the
operating system login name as the MySQL user name. It
combines that user name and the realm in the user'
MySQL account to construct the UPN. The client-side plugin
uses the UPN and the password to obtain a TGT, uses the
TGT to obtain a MySQL ST, and uses the ST to authenticate
to the MySQL server.
</p>
</li>
</ul>
</div>
<p>
If you are uncertain whether a TGT exists, you can use

<p>
If no valid ticket-granting ticket (TGT) exists at the time of
MySQL client application invocation, the application itself
may obtain and cache the TGT. If during the Kerberos
authentication process the client application causes a TGT to
be cached, any such TGT that was added can be destroyed after
it is no longer needed, by setting the appropriate
configuration parameter.

In MySQL, databases correspond to directories within the data
directory. Each table within a database corresponds to at least
one file within the database directory (and possibly more,
depending on the storage engine). Triggers also correspond to
files. Consequently, the case sensitivity of the underlying
operating system plays a part in the case sensitivity of
database, table, and trigger names. This means such names are
not case-sensitive in Windows, but are case-sensitive in most
varieties of Unix. One notable exception is macOS, which is
Unix-based but uses a default file system type (HFS+) that is
not case-sensitive. However, macOS also supports UFS volumes,
which are case-sensitive just as on any Unix. See
<a class="xref" href="extensions-to-ansi.html" title="1.7.1 MySQL Extensions to Standard SQL">
Section 1.7.1, “MySQL Extensions to Standard SQL”
</a>
. The
<a class="link" href="server-system-variables.html#sysvar_lower_case_table_names">
<code class="literal">
lower_case_table_names
</code>
</a>
system
variable also affects how the server handles identifier case
sensitivity, as described later in this section.

Although database, table, and trigger names are not
case-sensitive on some platforms, you should not refer to one
of these using different cases within the same statement. The
following statement would not work because it refers to a
table both as
<code class="literal">
my_table
</code>
and as
<code class="literal">
MY_TABLE
</code>

<p>
Partition, subpartition, column, index, stored routine, event,
and resource group names are not case-sensitive on any platform,
nor are column aliases.
</p>
<p>
However, names of logfile groups are case-sensitive. This
differs from standard SQL.
</p>
<p>
By default, table aliases are case-sensitive on Unix, but not so
on Windows or macOS. The following statement would not work on
Unix, because it refers to the alias both as
<code class="literal">
a
</code>
and as
<code class="literal">

<p>
However, this same statement is permitted on Windows. To avoid
problems caused by such differences, it is best to adopt a
consistent convention, such as always creating and referring to
databases and tables using lowercase names. This convention is
recommended for maximum portability and ease of use.

20.8.3.2 Upgrading a Group Replication Member
</h4>
</div>
</div>
</div>
<a class="indexterm" name="idm46045131600000">
</a>
<p>
This section explains the steps required for upgrading a member
of a group. This procedure is part of the methods described at
<a class="xref" href="group-replication-online-upgrade-methods.html" title="20.8.3.3 Group Replication Online Upgrade Methods">
Section 20.8.3.3, “Group Replication Online Upgrade Methods”
</a>
. The
process of upgrading a member of a group is common to all
methods and is explained first. The way which you join upgraded
members can depend on which method you are following, and other
factors such as whether the group is operating in single-primary
or multi-primary mode. How you upgrade the server instance,
using either the in-place or provision approach, does not impact
on the methods described here.
</p>
<p>
The process of upgrading a member consists of removing it from
the group, following your chosen method of upgrading the member,
and then rejoining the upgraded member to a group. The
recommended order of upgrading members in a single-primary group
is to upgrade all secondaries, and then upgrade the primary
last. If the primary is upgraded before a secondary, a new
primary using the older MySQL version is chosen, but there is no
need for this step.
</p>
<p>
To upgrade a member of a group:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Connect a client to the group member and issue
<a class="link" href="stop-group-replication.html" title="15.4.3.2 STOP GROUP_REPLICATION Statement">
<code class="literal">
STOP GROUP_REPLICATION
</code>
</a>
.
Before proceeding, ensure that the member's status is
<code class="literal">
OFFLINE
</code>
by monitoring the
<a class="link" href="performance-schema-replication-group-members-table.html" title="29.12.11.16 The replication_group_members Table">
<code class="literal">
replication_group_members
</code>
</a>
table.
</p>
</li>
<li class="listitem">
<p>
Disable Group Replication from starting up automatically so
that you can safely connect to the member after upgrading
and configure it without it rejoining the group by setting
<a class="link" href="group-replication-system-variables.html#sysvar_group_replication_start_on_boot">
<code class="literal">
group_replication_start_on_boot=0
</code>
</a>
.
</p>
<div class="important" style="margin-left: 0.5in; margin-right: 0.5in;">
<div class="admon-title">
Important
</div>
<p>
If an upgraded member has
<a class="link" href="group-replication-system-variables.html#sysvar_group_replication_start_on_boot">
<code class="literal">
group_replication_start_on_boot=1
</code>
</a>
then it could
rejoin the group before you can perform the MySQL upgrade
procedure and could result in issues. For example, if the
upgrade fails and the server restarts again, then a
possibly broken server could try to join the group.
</p>
</div>
</li>
<li class="listitem">
<p>
Stop the member, for example using
<a class="link" href="mysqladmin.html" title="6.5.2 mysqladmin — A MySQL Server Administration Program">
<span class="command">
<strong>
mysqladmin
shutdown
</strong>
</span>
</a>
or the
<a class="link" href="shutdown.html" title="15.7.8.9 SHUTDOWN Statement">
<code class="literal">
SHUTDOWN
</code>
</a>
statement. Any other
members in the group continue running.
</p>
</li>
<li class="listitem">
<p>
Upgrade the member, using the in-place or provisioning
approach. See
<a class="xref" href="upgrading.html" title="Chapter 3 Upgrading MySQL">
Chapter 3,
<i>
Upgrading MySQL
</i>
</a>
for details. When
restarting the upgraded member, because
<a class="link" href="group-replication-system-variables.html#sysvar_group_replication_start_on_boot">
<code class="literal">
group_replication_start_on_boot
</code>
</a>
is set to 0, Group
Replication does not start on the instance, and therefore it
does not rejoin the group.
</p>
</li>
<li class="listitem">
<p>
Once the MySQL upgrade procedure has been performed on the
member,
<a class="link" href="group-replication-system-variables.html#sysvar_group_replication_start_on_boot">
<code class="literal">
group_replication_start_on_boot
</code>
</a>
must be set to 1 to ensure Group Replication starts
correctly after restart. Restart the member.
</p>
</li>
<li class="listitem">
<p>
Connect to the upgraded member and issue
<a class="link" href="start-group-replication.html" title="15.4.3.1 START GROUP_REPLICATION Statement">
<code class="literal">
START GROUP_REPLICATION
</code>
</a>
. This
rejoins the member to the group. The Group Replication
metadata is in place on the upgraded server, therefore there
is usually no need to reconfigure Group Replication. The
server has to catch up with any transactions processed by
the group while the server was offline. Once it has caught
up with the group, it becomes an online member of the group.
</p>
<div class="note" style="margin-left: 0.5in; margin-right: 0.5in;">
<div class="admon-title">
Note
</div>
<p>
The longer it takes to upgrade a server, the more time
that member is offline and therefore the more time it
takes for the server to catch up when added back to the
group.
</p>
</div>
</li>
</ul>
</div>
<p>
When an upgraded member joins a group which has any member
running an earlier MySQL Server version, the upgraded member
joins with
<a class="link" href="server-system-variables.html#sysvar_super_read_only">
<code class="literal">
super_read_only=on
</code>
</a>
.
This ensures that no writes are made to upgraded members until
all members are running the newer version. In a multi-primary
mode group, when the upgrade has been completed successfully and
the group is ready to process transactions, members that are
intended as writeable primaries must be set to read/write mode.
When all members of a group have been upgraded to the same
release, they all change back to read/write mode automatically.

<p>
If an integer argument

is
specified, it is used as the seed value:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: circle; ">
<li class="listitem">
<p>
With a constant initializer argument, the seed is
initialized once when the statement is prepared, prior
to execution.
</p>
</li>
<li class="listitem">
<p>
With a nonconstant initializer argument (such as a
column name), the seed is initialized with the value for
each invocation of

<code class="literal">
RAND()
</code>

</p>

One implication of this behavior is that for equal argument

<code class="literal">
RAND(

repeatable sequence of column values. In the following

Uses for Session State Trackers
</h4>
</div>
</div>
</div>
<p>
Session state trackers have uses such as these:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
To facilitate session migration.
</p>
</li>
<li class="listitem">
<p>
To facilitate transaction switching.
</p>
</li>
</ul>
</div>
<p>
The tracker mechanism provides a means for MySQL connectors and
client applications to determine whether any session context is
available to permit session migration from one server to
another. (To change sessions in a load-balanced environment, it
is necessary to detect whether there is session state to take
into consideration when deciding whether a switch can be made.)
</p>
<p>
The tracker mechanism permits applications to know when
transactions can be moved from one session to another.
Transaction state tracking enables this, which is useful for
applications that may wish to move transactions from a busy
server to one that is less loaded. For example, a load-balancing
connector managing a client connection pool could move
transactions between available sessions in the pool.
</p>
<p>
However, session switching cannot be done at arbitrary times. If
a session is in the middle of a transaction for which reads or
writes have been done, switching to a different session implies
a transaction rollback on the original session. A session switch
must be done only when a transaction does not yet have any reads
or writes performed within it.
</p>
<p>
Examples of when transactions might reasonably be switched:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Immediately after
<a class="link" href="commit.html" title="15.3.1 START TRANSACTION, COMMIT, and ROLLBACK Statements">

<code class="literal">

</a>
</p>
</li>
</ul>
</div>
<p>
In addition to knowing transaction state, it is useful to know
transaction characteristics, so as to use the same
characteristics if the transaction is moved to a different
session. The following characteristics are relevant for this
purpose:

This section provides information about compiling NDB Cluster on
Linux and other Unix-like platforms. Building NDB Cluster from
source is similar to building the standard MySQL Server,
although it differs in a few key respects discussed here. For
general information about building MySQL from source, see
<a class="xref" href="source-installation.html" title="2.8 Installing MySQL from Source">
Section 2.8, “Installing MySQL from Source”
</a>
. For information about
compiling NDB Cluster on Windows platforms, see
<a class="xref" href="mysql-cluster-install-windows-source.html" title="25.3.2.2 Compiling and Installing NDB Cluster from Source on Windows">
Section 25.3.2.2, “Compiling and Installing NDB Cluster from Source on Windows”
</a>
.
</p>
<p>
MySQL NDB Cluster 8.4 is built from the MySQL
Server 8.4 sources, available from the MySQL
downloads page at
<a class="ulink" href="https://dev.mysql.com/downloads/" target="_top">
https://dev.mysql.com/downloads/
</a>
. The
archived source file should have a name similar to
<code class="filename">
mysql-8.4.0.tar.gz
</code>
. You
can also obtain the sources from GitHub at
<a class="ulink" href="https://github.com/mysql/mysql-server" target="_blank">

<code class="option">

</a>
option for
<span class="command">

it also causes

option is
enabled by default. This means that, by default, if
<span class="command">

cannot find the location of Java on
your system, the configuration process fails; if you do not
wish to enable Java and ClusterJ support, you must indicate
this explicitly by configuring the build using
<code class="option">

. Use
<a class="link" href="source-configuration-options.html#option_cmake_with_classpath">

copied to the other host machine or machines. (This assumes
that all data node hosts use the same architecture and

When compiling NDB Cluster from source, no special options are
required for building multithreaded data node binaries.

Section 2.8, “Installing MySQL from Source”

to make
<a class="link" href="mysqld.html" title="6.3.1 mysqld — The MySQL Server">
<span class="command">
<strong>
mysqld

<span class="command">
<strong>
mysqld
</strong>
</span>
</a>
executable and its associated
support files on several machines. The easiest way to do this
is to copy the entire
<code class="filename">
/usr/local/mysql
</code>
directory and all directories and files contained within it to
the other SQL node host or hosts, then repeat the steps from
<a class="xref" href="source-installation.html" title="2.8 Installing MySQL from Source">
Section 2.8, “Installing MySQL from Source”
</a>
on each machine. If you
configure the build with a nondefault
<code class="option">
PREFIX
</code>
option, you must adjust the directory accordingly.

Passwords occur in several contexts within MySQL. The following
sections provide guidelines that enable end users and
administrators to keep these passwords secure and avoid exposing
them. In addition, the
<code class="literal">
validate_password

can be used to enforce a policy on acceptable password. See

MySQL provides standard SQL pattern matching as well as a form
of pattern matching based on extended regular expressions
similar to those used by Unix utilities such as
<span class="command">
<strong>
vi
</strong>
</span>
,
<span class="command">
<strong>
grep
</strong>
</span>
, and
<span class="command">
<strong>
sed
</strong>
</span>
.
</p>
<p>
SQL pattern matching enables you to use
<code class="literal">
_
</code>
to match any single character and
<code class="literal">
%
</code>
to
match an arbitrary number of characters (including zero
characters). In MySQL, SQL patterns are case-insensitive by
default. Some examples are shown here. Do not use
<code class="literal">
=
</code>
or
<code class="literal">
<>
</code>
when you
use SQL patterns. Use the
<a class="link" href="string-comparison-functions.html#operator_like">
<code class="literal">
LIKE
</code>
</a>
or
<a class="link" href="string-comparison-functions.html#operator_not-like">
<code class="literal">
NOT LIKE
</code>
</a>
comparison operators
instead.

<p>
The other type of pattern matching provided by MySQL uses
extended regular expressions. When you test for a match for
this type of pattern, use the
<a class="link" href="regexp.html#function_regexp-like">
<code class="literal">
REGEXP_LIKE()
</code>
</a>
function (or the
<a class="link" href="regexp.html#operator_regexp">
<code class="literal">
REGEXP
</code>
</a>
or
<a class="link" href="regexp.html#operator_regexp">
<code class="literal">
RLIKE
</code>
</a>
operators, which are synonyms for
<a class="link" href="regexp.html#function_regexp-like">
<code class="literal">
REGEXP_LIKE()
</code>
</a>
).
</p>
<p>
The following list describes some characteristics of extended
regular expressions:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<code class="literal">
.
</code>
matches any single character.
</p>
</li>
<li class="listitem">
<p>
A character class
<code class="literal">
[...]
</code>
matches any
character within the brackets. For example,
<code class="literal">
[abc]
</code>
matches
<code class="literal">
a
</code>
,
<code class="literal">
b
</code>
, or
<code class="literal">
c
</code>
. To name a
range of characters, use a dash.
<code class="literal">
[a-z]
</code>
matches any letter, whereas
<code class="literal">
[0-9]
</code>
matches any digit.
</p>
</li>
<li class="listitem">
<p>
<code class="literal">
*
</code>
matches zero or more instances of the
thing preceding it. For example,
<code class="literal">
x*
</code>
matches any number of
<code class="literal">
x
</code>
characters,
<code class="literal">
[0-9]*
</code>
matches any number of digits,
and
<code class="literal">
.*
</code>
matches any number of anything.
</p>
</li>
<li class="listitem">
<p>
A regular expression pattern match succeeds if the pattern
matches anywhere in the value being tested. (This differs
from a
<a class="link" href="string-comparison-functions.html#operator_like">
<code class="literal">
LIKE
</code>
</a>
pattern match,
which succeeds only if the pattern matches the entire
value.)
</p>
</li>
<li class="listitem">
<p>
To anchor a pattern so that it must match the beginning or
end of the value being tested, use
<code class="literal">
^
</code>
at
the beginning or
<code class="literal">
$
</code>
at the end of the
pattern.
</p>
</li>
</ul>
</div>
<p>
To demonstrate how extended regular expressions work, the
<a class="link" href="string-comparison-functions.html#operator_like">
<code class="literal">
LIKE
</code>
</a>
queries shown previously are
rewritten here to use
<a class="link" href="regexp.html#function_regexp-like">
<code class="literal">
REGEXP_LIKE()
</code>
</a>
.
</p>
<p>
To find names beginning with
<code class="literal">
b
</code>
, use
<code class="literal">
^
</code>
to match the beginning of the name:

For attempts to assign a system thread to a user resource group
or a user thread to a system resource group, a warning occurs.

If installed, the

some overhead even when disabled. To avoid this overhead, do
not install the plugin unless you plan to use it.
</p>
</div>
<p>
To install or uninstall the
<code class="literal">

rewrite plugin, choose the appropriate script located in the
<code class="filename">
share
</code>
directory of your MySQL installation:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<code class="filename">
install_rewriter.sql

plugin and
its associated elements.

</code>
: Choose this
script to uninstall the
<code class="literal">

plugin
and its associated elements.
</p>
</li>
</ul>
</div>
<p>
Run the chosen script as follows:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-terminal"><div class="docs-select-all right" id="sa48340832"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal"><span class="token prompt">$> </span><span class="token command">mysql</span> <span class="token property">-u</span> root <span class="token property">-p</span> < install_rewriter<span class="token punctuation">.</span>sql

Substitute
<code class="filename">

<p>
Running an installation script should install and enable the
plugin. To verify that, connect to the server and execute this

<code class="literal">
mutex_instances
</code>
</a>
table lists
all the mutexes seen by the Performance Schema while the
server executes. A mutex is a synchronization mechanism used
in the code to enforce that only one thread at a given time
can have access to some common resource. The resource is said
to be
<span class="quote">
“
<span class="quote">
protected
</span>
”
</span>
by the mutex.
</p>
<p>
When two threads executing in the server (for example, two
user sessions executing a query simultaneously) do need to
access the same resource (a file, a buffer, or some piece of
data), these two threads compete against each other, so that
the first query to obtain a lock on the mutex causes the other
query to wait until the first is done and unlocks the mutex.
</p>
<p>
The work performed while holding a mutex is said to be in a
<span class="quote">
“
<span class="quote">
critical section,
</span>
”
</span>
and multiple queries do
execute this critical section in a serialized way (one at a
time), which is a potential bottleneck.

If names in the column usually differ in the first 10

indexes can make the index file much smaller, which could save a

Functional key parts enable indexing of values that cannot be
indexed otherwise, such as
<a class="link" href="json.html" title="13.5 The JSON Data Type">
<code class="literal">

</a>
values. However, this must be done correctly to achieve the
desired effect. For example, this syntax does not work:
</p>
<div class="copytoclipboard-wrapper">

<span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
The syntax fails because:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
The
<a class="link" href="json-search-functions.html#operator_json-inline-path">

</a>
.
</p>

<li class="listitem">
<p>

value with a data type of
<a class="link" href="blob.html" title="13.3.4 The BLOB and TEXT Types">
<code class="literal">

</a>
, and the hidden
generated column thus is assigned the same data type.
</p>
</li>
<li class="listitem">
<p>

and prefix lengths are not permitted in functional key

</p>
</li>
</ul>
</div>
<p>
To index the

</a>
function as follows:

<div class="copytoclipboard-wrapper">

<span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
The hidden generated column is assigned the
<a class="link" href="char.html" title="13.3.2 The CHAR and VARCHAR Types">
<code class="literal">
VARCHAR(30)
</code>
</a>
data type, which can
be indexed. But this approach produces a new issue when trying
to use the index:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<a class="link" href="cast-functions.html#function_cast">
<code class="literal">
CAST()
</code>
</a>
returns a string with
the collation
<code class="literal">
utf8mb4_0900_ai_ci
</code>
(the
server default collation).
</p>
</li>
<li class="listitem">
<p>
<a class="link" href="json-modification-functions.html#function_json-unquote">
<code class="literal">
JSON_UNQUOTE()
</code>
</a>
returns a
string with the collation
<code class="literal">
utf8mb4_bin
</code>
(hard coded).
</p>
</li>
</ul>
</div>
<p>
As a result, there is a collation mismatch between the indexed
expression in the preceding table definition and the
<code class="literal">
WHERE
</code>
clause expression in the following
query:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-sql"><div class="docs-select-all right" id="sa19802754"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">SELECT</span> <span class="token operator">*</span> <span class="token keyword">FROM</span> employees <span class="token keyword">WHERE</span> <span class="token keyword">data</span><span class="token operator">-</span><span class="token operator">>></span><span class="token string">'$.name'</span> <span class="token operator">=</span> <span class="token string">'James'</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
The index is not used because the expressions in the query and
the index differ. To support this kind of scenario for
functional key parts, the optimizer automatically strips
<a class="link" href="cast-functions.html#function_cast">
<code class="literal">
CAST()
</code>
</a>
when looking for an index
to use, but
<span class="emphasis">
<em>
only
</em>
</span>
if the collation of the
indexed expression matches that of the query expression. For an
index with a functional key part to be used, either of the
following two solutions work (although they differ somewhat in
effect):
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Solution 1. Assign the indexed expression the same collation

A

all values in the index must be distinct. An error occurs if you
try to add a new row with a key value that matches an existing
row. If you specify a prefix value for a column in a
<code class="literal">
UNIQUE

unique within the prefix length. A
<code class="literal">

supports multi-valued indexes. A
multi-valued index is a secondary index defined on a column that
stores an array of values. A
<span class="quote">
“
<span class="quote">
normal
</span>
”
</span>
index has one
index record for each data record (1:1). A multi-valued index
can have multiple index records for a single data record (N:1).
Multi-valued indexes are intended for indexing
<code class="literal">
JSON
</code>
arrays. For example, a multi-valued
index defined on the array of zip codes in the following JSON
document creates an index record for each zip code, with each
index record referencing the same data record.

Creating multi-valued Indexes

You can create a multi-valued index in a
<a class="link" href="create-table.html" title="15.1.20 CREATE TABLE Statement">
<code class="literal">
CREATE TABLE

</a>
,
<a class="link" href="alter-table.html" title="15.1.9 ALTER TABLE Statement">

</a>
, or
<a class="link" href="create-index.html" title="15.1.15 CREATE INDEX Statement">
<code class="literal">
CREATE INDEX
</code>
</a>
statement. This
requires using
<a class="link" href="cast-functions.html#function_cast">
<code class="literal">
CAST(... AS ...
ARRAY)
</code>
</a>
in the index definition, which casts same-typed
scalar values in a
<code class="literal">
JSON
</code>
array to an SQL data
type array. A virtual column is then generated transparently
with the values in the SQL data type array; finally, a
functional index (also referred to as a virtual index) is
created on the virtual column. It is the functional index
defined on the virtual column of values from the SQL data type
array that forms the multi-valued index.
</p>
<p>
The examples in the following list show the three different ways
in which a multi-valued index
<code class="literal">
zips
</code>
can be
created on an array
<code class="literal">
$.zipcode
</code>
on a
<code class="literal">
JSON
</code>
column
<code class="literal">
custinfo
</code>
in a
table named
<code class="literal">
customers
</code>
. In each case, the JSON
array is cast to an SQL data type array of
<code class="literal">
UNSIGNED
</code>
integer values.

Only one multi-valued key part can be used in a composite index.
The multi-valued key part may be used in any order relative to
the other parts of the key. In other words, the
<code class="literal">
ALTER
TABLE
</code>
statement just shown could have used
<code class="literal">
comp(id, (CAST(custinfo->'$.zipcode' AS UNSIGNED
ARRAY), modified))
</code>
(or any other ordering) and still
have been valid.

A multi-valued index can be defined as a unique key. If defined
as a unique key, attempting to insert a value already present in
the multi-valued index returns a duplicate key error. If
duplicate values are already present, attempting to add a unique
multi-valued index fails, as shown here:

If a multi-valued key part has an empty array, no
entries are added to the index, and the data record is
not accessible by an index scan.

If multi-valued key part generation returns a

Limitations and Restrictions on Multi-valued Indexes
</h5>
<p>
Multi-valued indexes are subject to the limitations and
restrictions listed here:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Only one multi-valued key part is permitted per multi-valued

<p>
In this case, all values matching the JSON expression are
stored in the index as a single flat array.
</p>
</li>
<li class="listitem">
<p>
An index with a multi-valued key part does not support
ordering and therefore cannot be used as a primary key. For
the same reason, a multi-valued index cannot be defined
using the
<code class="literal">
ASC
</code>
or
<code class="literal">
DESC
</code>
keyword.

<p>
A multi-valued index cannot be a covering index.

<p>
The maximum number of values per record for a multi-valued
index is determined by the amount of data than can be stored
on a single undo log page, which is 65221 bytes (64K minus
315 bytes for overhead), which means that the maximum total
length of key values is also 65221 bytes. The maximum number
of keys depends on various factors, which prevents defining
a specific limit. Tests have shown a multi-valued index to
permit as many as 1604 integer keys per record, for example.
When the limit is reached, an error similar to the following
is reported:
<span class="errortext">
ERROR 3905 (HY000): Exceeded max
number of values per record for multi-valued index 'idx' by
1 value(s).

The only type of expression that is permitted in a
multi-valued key part is a

element in a JSON document inserted into the indexed column,
but must itself be syntactically valid.

<p>
The
<em class="replaceable">
<code>
index_type

</em>
clause cannot be
used for
<code class="literal">
FULLTEXT INDEX
</code>
specifications.
Full-text index implementation is storage-engine dependent.
Spatial indexes are implemented as R-tree indexes.
</p>
<p>
If you specify an index type that is not valid for a given
storage engine, but another index type is available that the
engine can use without affecting query results, the engine
uses the available type. The parser recognizes
<code class="literal">
RTREE
</code>
as a type name. This is permitted
only for
<code class="literal">
SPATIAL

indexes.
</p>
<p>
<code class="literal">

<a class="link" href="mysql-cluster.html" title="Chapter 25 MySQL NDB Cluster 8.4">

For indexes on

</a>
table
columns, the
<code class="literal">
USING

option can be
specified only for a unique index or primary key.
<code class="literal">
USING HASH

prevents the creation of an
ordered index; otherwise, creating a unique index or
primary key on an
<a class="link" href="mysql-cluster.html" title="Chapter 25 MySQL NDB Cluster 8.4">
<code class="literal">
NDB

</a>

automatically results in the creation of both an ordered
index and a hash index, each of which indexes the same set
of columns.
</p>
<p>
For unique indexes that include one or more
<code class="literal">
NULL
</code>
columns of an
<a class="link" href="mysql-cluster.html" title="Chapter 25 MySQL NDB Cluster 8.4">
<code class="literal">
NDB
</code>
</a>
table, the hash index can
be used only to look up literal values, which means that
<code class="literal">
IS [NOT] NULL
</code>
conditions require a full
scan of the table. One workaround is to make sure that a
unique index using one or more
<code class="literal">
NULL
</code>
columns on such a table is always created in such a way
that it includes the ordered index; that is, avoid
employing
<code class="literal">
USING HASH
</code>
when creating the
index.
</p>
</div>
<p>
If you specify an index type that is not valid for a given
storage engine, but another index type is available that the
engine can use without affecting query results, the engine
uses the available type. The parser recognizes
<code class="literal">
RTREE

as a type name, but currently this
cannot be specified for any storage engine.

When an operator is used with operands of different types, type
conversion occurs to make the operands compatible. Some
conversions occur implicitly. For example, MySQL automatically
converts strings to numbers as necessary, and vice versa.

It is also possible to convert a number to a string explicitly

Conversion occurs implicitly with the

expects string arguments.

be more ODBC-friendly. This is not done for the arguments to
<a class="link" href="comparison-operators.html#operator_in">
<code class="literal">
IN()

</a>
. To be safe, always use
complete datetime, date, or time strings when doing
comparisons. For example, to achieve best results when using
<a class="link" href="comparison-operators.html#operator_between">

A single-row subquery from a table or tables is not considered

not converted to a temporal value. To compare the operands as
<a class="link" href="datetime.html" title="13.2.2 The DATE, DATETIME, and TIMESTAMP Types">
<code class="literal">

values, use
<a class="link" href="cast-functions.html#function_cast">

If one of the arguments is a decimal value, comparison depends
on the other argument. The arguments are compared as decimal
values if the other argument is a decimal or integer value, or
as floating-point values if the other argument is a
floating-point value.
</p>
</li>
<li class="listitem">
<p>
In all other cases, the arguments are compared as
floating-point (double-precision) numbers. For example, a
comparison of string and numeric operands takes place as a
comparison of floating-point numbers.

</p>
<p>
Comparison of JSON values takes place at two levels. The first
level of comparison is based on the JSON types of the compared
values. If the types differ, the comparison result is determined
solely by which type has higher precedence. If the two values have
the same JSON type, a second level of comparison occurs using
type-specific rules. For comparison of JSON and non-JSON values,
the non-JSON value is converted to JSON and the values compared as
JSON values. For details, see
<a class="xref" href="json.html#json-comparison" title="Comparison and Ordering of JSON Values">
Comparison and Ordering of JSON Values

The following examples illustrate conversion of strings to numbers
for comparison operations:

</div>
<p>
For comparisons of a string column with a number, MySQL cannot use
an index on the column to look up the value quickly. If
<em class="replaceable">
<code>
str_col
</code>
</em>
is an indexed string column,
the index cannot be used when performing the lookup in the
following statement:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-sql"><div class="docs-select-all right" id="sa57983256"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">SELECT</span> <span class="token operator">*</span> <span class="token keyword">FROM</span> <em class="replaceable">tbl_name</em> <span class="token keyword">WHERE</span> <em class="replaceable">str_col</em><span class="token operator">=</span><span class="token number">1</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
The reason for this is that there are many different strings that
may convert to the value
<code class="literal">
1
</code>
, such as
<code class="literal">
'1'
</code>
,
<code class="literal">
' 1'

Comparisons between floating-point numbers and large integer
values are approximate because the integer is converted to
double-precision floating point before comparison, which is not
capable of representing all 64-bit integers exactly. For example,
the integer value 2
<sup>
53
</sup>
+ 1 is not
representable as a float, and is rounded to
2
<sup>
53
</sup>
or 2
<sup>
53
</sup>
+
2 before a float comparison, depending on the platform.
</p>
<p>
To illustrate, only the first of the following comparisons
compares equal values, but both comparisons return true (1):

When conversions from string to floating-point and from integer to
floating-point occur, they do not necessarily occur the same way.
The integer may be converted to floating-point by the CPU, whereas
the string is converted digit by digit in an operation that
involves floating-point multiplications. Also, results can be
affected by factors such as computer architecture or the compiler
version or optimization level. One way to avoid such problems is
to use
<a class="link" href="cast-functions.html#function_cast">
<code class="literal">
CAST()
</code>
</a>
so that a value is
not converted implicitly to a float-point number:

is not a denormal value,

the conversion is lossless even if

Implicit conversion of a numeric or temporal value to string
produces a value that has a character set and collation determined
by the
<a class="link" href="server-system-variables.html#sysvar_character_set_connection">

and
<a class="link" href="server-system-variables.html#sysvar_collation_connection">

system
variables. (These variables commonly are set with
<a class="link" href="set-names.html" title="15.7.6.3 SET NAMES Statement">

connection character sets, see

Section 12.4, “Connection Character Sets and Collations”

</p>
<p>
This means that such a conversion results in a character
(nonbinary) string (a
<a class="link" href="char.html" title="13.3.2 The CHAR and VARCHAR Types">
<code class="literal">
CHAR

</a>

<code class="literal">

</a>
value), except in the case
that the connection character set is set to
<code class="literal">
binary
</code>
. In that case, the conversion result is
a binary string (a
<a class="link" href="binary-varbinary.html" title="13.3.3 The BINARY and VARBINARY Types">
<code class="literal">

For integer expressions, the preceding remarks about expression
<span class="emphasis">
<em>
evaluation
</em>
</span>
apply somewhat differently for
expression
<span class="emphasis">

; for example, in a
statement such as this:

In this case, the table in the column resulting from the

<code class="literal">

does not fit in an

<code class="literal">

Specify a list of directories to search for a CA file. On
Unix platforms, the directory names are separated by colons
(
<code class="literal">
:
</code>
); on Windows systems, the semicolon
character (
<code class="literal">
;
</code>
) is used as the separator. A
directory reference may be relative or absolute; it may
contain one or more environment variables, each denoted by a
prefixed dollar sign (
<code class="literal">
$
</code>
), and expanded
prior to use.
</p>
<p>
Searching begins with the leftmost named directory and
proceeds from left to right until a file is found. An empty
string denotes an empty search path, which causes all
searches to fail. A string consisting of a single dot
(
<code class="literal">
.
</code>
) indicates that the search path
limited to the current working directory.
</p>
<p>
If no search path is supplied, the compiled-in default value
is used. This value depends on the platform used: On
Windows, this is
<code class="literal">
\ndb-tls
</code>
; on other
platforms (including Linux), it is
<code class="literal">
$HOME/ndb-tls
</code>
. This can be overridden by
compiling NDB Cluster using

You may have noticed in the preceding examples that the result
rows are displayed in no particular order. It is often easier
to examine query output when the rows are sorted in some
meaningful way. To sort a result, use an

On character type columns, sorting—like all other
comparison operations—is normally performed in a
case-insensitive fashion. This means that the order is
undefined for columns that are identical except for their
case. You can force a case-sensitive sort for a column by
using
<a class="link" href="cast-functions.html#operator_binary">
<code class="literal">
BINARY
</code>
</a>
like so:
<code class="literal">
ORDER BY BINARY
<em class="replaceable">
<code>
col_name
</code>
</em>
</code>
.
</p>
<p>
The default sort order is ascending, with smallest values
first. To sort in reverse (descending) order, add the
<code class="literal">
DESC
</code>
keyword to the name of the column you
are sorting by:

About Data-at-Rest Encryption
</h3>
</div>
</div>
</div>
<p>
<code class="literal">
InnoDB
</code>
uses a two tier encryption key
architecture, consisting of a master encryption key and tablespace
keys. When a tablespace is encrypted, a tablespace key is
encrypted and stored in the tablespace header. When an application
or authenticated user wants to access encrypted tablespace data,
<code class="literal">
InnoDB
</code>
uses a master encryption key to decrypt
the tablespace key. The decrypted version of a tablespace key
never changes, but the master encryption key can be changed as
required. This action is referred to as
<span class="emphasis">
<em>
master key
rotation
</em>
</span>
.
</p>
<p>
The data-at-rest encryption feature relies on a keyring component
or plugin for master encryption key management.
</p>
<p>
All MySQL editions provide a
<code class="literal">
component_keyring_file
</code>
component, which stores
keyring data in a file local to the server host.
</p>
<p>
MySQL Enterprise Edition offers additional keyring components and plugins:
</p>

<p>
For encryption key management, the
<code class="literal">
component_keyring_file
</code>
and
<code class="literal">
component_keyring_encrypted_file
</code>
components
are not intended as a regulatory compliance solution. Security
standards such as PCI, FIPS, and others require use of key
management systems to secure, manage, and protect encryption
keys in key vaults or hardware security modules (HSMs).
</p>
</div>
<p>
A secure and robust encryption key management solution is critical
for security and for compliance with various security standards.
When the data-at-rest encryption feature uses a centralized key
management solution, the feature is referred to as
<span class="quote">
“
<span class="quote">
MySQL
Enterprise Transparent Data Encryption (TDE)
</span>
”
</span>
.
</p>
<p>
The data-at-rest encryption feature supports the Advanced
Encryption Standard (AES) block-based encryption algorithm. It
uses Electronic Codebook (ECB) block encryption mode for
tablespace key encryption and Cipher Block Chaining (CBC) block
encryption mode for data encryption.
</p>

Only one keyring component or plugin should be enabled at a

Once encrypted tablespaces are created in a MySQL instance,
the keyring component or plugin that was loaded when
creating the encrypted tablespace must continue to be loaded

If you use the

create a backup of the keyring data file immediately after
creating the first encrypted tablespace, before master key

The default encryption setting for a schema can also be defined

<p>
By default, a table inherits the encryption setting of the schema

created in an encryption-enabled schema is encrypted by default.
This behavior enables a DBA to control table encryption usage by
defining and enforcing schema and general tablespace encryption
defaults.

<code class="literal">

The master encryption key should be rotated periodically and
whenever you suspect that the key has been compromised.
</p>
<p>
Master key rotation is an atomic, instance-level operation. Each
time the master encryption key is rotated, all tablespace keys in
the MySQL instance are re-encrypted and saved back to their
respective tablespace headers. As an atomic operation,
re-encryption must succeed for all tablespace keys once a rotation
operation is initiated. If master key rotation is interrupted by a

forward on server restart. For more information, see
<a class="xref" href="innodb-data-encryption.html#innodb-data-encryption-recovery" title="Encryption and Recovery">

</p>
<p>
Rotating the master encryption key only changes the master
encryption key and re-encrypts tablespace keys. It does not
decrypt or re-encrypt associated tablespace data.

<code class="literal">

<code class="literal">

clauses to refer to the column:

</div>
<p>
Standard SQL disallows references to column aliases in a
<code class="literal">
WHERE
</code>
clause. This restriction is imposed
because when the
<code class="literal">
WHERE
</code>
clause is evaluated,
the column value may not yet have been determined. For
example, the following query is illegal:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-sql"><div class="docs-select-all right" id="sa72728627"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">SELECT</span> id<span class="token punctuation">,</span> <span class="token function">COUNT</span><span class="token punctuation">(</span><span class="token operator">*</span><span class="token punctuation">)</span> <span class="token keyword">AS</span> cnt <span class="token keyword">FROM</span> <em class="replaceable">tbl_name</em>
<span class="token keyword">WHERE</span> cnt <span class="token operator">></span> <span class="token number">0</span> <span class="token keyword">GROUP</span> <span class="token keyword">BY</span> id<span class="token punctuation">;</span></code></pre>
</div>
<p>
The
<code class="literal">
WHERE
</code>
clause determines which rows
should be included in the
<code class="literal">
GROUP BY
</code>
clause,
but it refers to the alias of a column value that is not known
until after the rows have been selected, and grouped by the
<code class="literal">
GROUP BY
</code>
.
</p>
<p>
In the select list of a query, a quoted column alias can be
specified using identifier or string quoting characters:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-sql"><div class="docs-select-all right" id="sa39201726"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">SELECT</span> <span class="token number">1</span> <span class="token keyword">AS</span> <span class="token punctuation">`</span><span class="token keyword">one</span><span class="token punctuation">`</span><span class="token punctuation">,</span> <span class="token number">2</span> <span class="token keyword">AS</span> <span class="token string">'two'</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
Elsewhere in the statement, quoted references to the alias
must use identifier quoting or the reference is treated as a
string literal. For example, this statement groups by the
values in column
<code class="literal">
id
</code>
, referenced using the
alias
<code class="literal">
`a`
</code>
:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-sql"><div class="docs-select-all right" id="sa51225262"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">SELECT</span> id <span class="token keyword">AS</span> <span class="token string">'a'</span><span class="token punctuation">,</span> <span class="token function">COUNT</span><span class="token punctuation">(</span><span class="token operator">*</span><span class="token punctuation">)</span> <span class="token keyword">AS</span> cnt <span class="token keyword">FROM</span> <em class="replaceable">tbl_name</em>

MySQL account names consist of a user name and a host name, which
enables creation of distinct accounts for users with the same user
name who connect from different hosts. This section describes the
syntax for account names, including special values and wildcard
rules.
</p>
<p>
In most respects, account names are similar to MySQL role names,
with some differences described at
<a class="xref" href="role-names.html" title="8.2.5 Specifying Role Names">
Section 8.2.5, “Specifying Role Names”
</a>
.
</p>
<p>
Account names appear in SQL statements such as
<a class="link" href="create-user.html" title="15.7.1.3 CREATE USER Statement">
<code class="literal">
CREATE USER
</code>
</a>
,
<a class="link" href="grant.html" title="15.7.1.6 GRANT Statement">
<code class="literal">
GRANT
</code>
</a>
, and
<a class="link" href="set-password.html" title="15.7.1.10 SET PASSWORD Statement">
<code class="literal">
SET
PASSWORD
</code>
</a>
and follow these rules:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Account name syntax is
<code class="literal">
'
<em class="replaceable">
<code>
user_name
</code>
</em>
'@'
<em class="replaceable">
<code>
host_name
</code>
</em>
'
</code>

</p>
</li>
<li class="listitem">
<p>
The
<code class="literal">
@'
<em class="replaceable">
<code>
host_name

</em>
'

part is optional. An account name consisting only of a user
name is equivalent to
<code class="literal">
'
<em class="replaceable">
<code>
user_name
</code>
</em>
'@'%'
</code>
.
For example,
<code class="literal">
'me'
</code>
is equivalent to
<code class="literal">
'me'@'%'
</code>
.
</p>
</li>
<li class="listitem">
<p>
The user name and host name need not be quoted if they are
legal as unquoted identifiers. Quotes must be used if a
<em class="replaceable">
<code>

</em>
string contains special
characters (such as space or
<code class="literal">
-
</code>
), or a
<em class="replaceable">
<code>
host_name
</code>
</em>
string contains special
characters or wildcard characters (such as
<code class="literal">
.

or
<code class="literal">
%

). For example, in
the account name
<code class="literal">
'test-user'@'%.com'

the user name and host name parts require quotes.

marks (
<code class="literal">

The user name and host name parts, if quoted, must be quoted
separately. That is, write
<code class="literal">

MySQL stores account names in grant tables in the

for the user name and host name parts:

The
<code class="literal">
user

table contains one row for each
account. The
<code class="literal">
User
</code>
and
<code class="literal">
Host
</code>
columns store the user name and host
name. This table also indicates which global privileges the
account has.
</p>
</li>
<li class="listitem">
<p>
Other grant tables indicate privileges an account has for
databases and objects within databases. These tables have
<code class="literal">

the same
<code class="literal">

and
<code class="literal">

Grant Table Scope Column Properties
</a>
.
</p>
<p>
User names and host names have certain special values or wildcard
conventions, as described following.
</p>
<p>
The user name part of an account name is either a nonblank value
that literally matches the user name for incoming connection
attempts, or a blank value (the empty string) that matches any
user name. An account with a blank user name is an anonymous user.
To specify an anonymous user in SQL statements, use a quoted empty
user name part, such as
<code class="literal">
''@'localhost'
</code>
.
</p>

The host name part of an account name can take many forms, and
wildcards are permitted:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
A host value can be a host name or an IP address (IPv4 or
IPv6). The name
<code class="literal">
'localhost'
</code>
indicates the
local host. The IP address
<code class="literal">
'127.0.0.1'
</code>
indicates the IPv4 loopback interface. The IP address
<code class="literal">
'::1'
</code>
indicates the IPv6 loopback
interface.

Use of the
<code class="literal">
%
</code>
and
<code class="literal">

wildcard characters is permitted in host name or IP address
values, but is deprecated and thus subject to removal in a
future version of MySQL. These characters have the same
meaning as for pattern-matching operations performed with the
<a class="link" href="string-comparison-functions.html#operator_like">
<code class="literal">
LIKE
</code>
</a>
operator. For example, a
host value of
<code class="literal">
'%'
</code>
matches any host name,
whereas a value of
<code class="literal">
'%.mysql.com'
</code>
matches
any host in the
<code class="literal">
mysql.com
</code>
domain.
<code class="literal">
'198.51.100.%'
</code>
matches any host in the
198.51.100 class C network.

</a>
<a class="indexterm" name="idm46045249938528">

<p>
Because IP wildcard values are permitted in host values (for
example,
<code class="literal">
'198.51.100.%'
</code>
to match every host
on a subnet), someone could try to exploit this capability by
naming a host
<code class="literal">
198.51.100.somewhere.com
</code>
. To
foil such attempts, MySQL does not perform matching on host
names that start with digits and a dot. For example, if a host
is named
<code class="literal">
1.2.example.com
</code>
, its name never
matches the host part of account names. An IP wildcard value
can match only IP addresses, not host names.

, MySQL treats
<code class="literal">
%

and
<code class="literal">

in grants as literal characters, and not
as wildcards. Use of these wildcards is deprecated (regardless
of this variable's value); you should expect this
functionality to be removed in a future version of MySQL.

The server performs matching of host values in account names
against the client host using the value returned by the system DNS
resolver for the client host name or IP address. Except in the
case that the account host value is specified using netmask
notation, the server performs this comparison as a string match,
even for an account host value given as an IP address. This means
that you should specify account host values in the same format
used by DNS. Here are examples of problems to watch out for:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
Suppose that a host on the local network has a fully qualified
name of
<code class="literal">
host1.example.com
</code>
. If DNS returns
name lookups for this host as
<code class="literal">
host1.example.com
</code>
, use that name in account
host values. If DNS returns just
<code class="literal">
host1
</code>
, use
<code class="literal">
host1
</code>
instead.
</p>
</li>
<li class="listitem">
<p>
If DNS returns the IP address for a given host as
<code class="literal">
198.51.100.2
</code>
, that matches an account host
value of
<code class="literal">
198.51.100.2
</code>
but not
<code class="literal">
198.051.100.2
</code>
. Similarly, it matches an
account host pattern like
<code class="literal">
198.51.100.%
</code>
but
not
<code class="literal">
198.051.100.%
</code>
.
</p>
</li>
</ul>
</div>
<p>
To avoid problems like these, it is advisable to check the format
in which your DNS returns host names and addresses. Use values in
the same format in MySQL account names.

<p>
<code class="literal">
InnoDB
</code>
uses operating system
<a class="link" href="glossary.html#glos_thread" title="thread">
threads
</a>
to process requests
from user transactions. (Transactions may issue many requests to
<code class="literal">
InnoDB
</code>
before they commit or roll back.) On
modern operating systems and servers with multi-core processors,
where context switching is efficient, most workloads run well
without any limit on the number of concurrent threads.
</p>
<p>
In situations where it is helpful to minimize context switching
between threads,
<code class="literal">
InnoDB
</code>
can use a number of
techniques to limit the number of concurrently executing operating
system threads (and thus the number of requests that are processed
at any one time). When
<code class="literal">
InnoDB
</code>
receives a new
request from a user session, if the number of threads concurrently
executing is at a pre-defined limit, the new request sleeps for a
short time before it tries again. Threads waiting for locks are
not counted in the number of concurrently executing threads.
</p>
<p>
You can limit the number of concurrent threads by setting the
configuration parameter
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
. Once
the number of executing threads reaches this limit, additional
threads sleep for a number of microseconds, set by the
configuration parameter
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_sleep_delay">
<code class="literal">
innodb_thread_sleep_delay
</code>
</a>
, before
being placed into the queue.
</p>
<p>
You can set the configuration option
<a class="link" href="innodb-parameters.html#sysvar_innodb_adaptive_max_sleep_delay">
<code class="literal">
innodb_adaptive_max_sleep_delay
</code>
</a>
to the highest value you would allow for
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_sleep_delay">
<code class="literal">
innodb_thread_sleep_delay
</code>
</a>
, and
<code class="literal">
InnoDB
</code>
automatically adjusts
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_sleep_delay">
<code class="literal">
innodb_thread_sleep_delay
</code>
</a>
up or
down depending on the current thread-scheduling activity. This
dynamic adjustment helps the thread scheduling mechanism to work
smoothly during times when the system is lightly loaded and when
it is operating near full capacity.
</p>
<p>
The default value for
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
and the
implied default limit on the number of concurrent threads has been
changed in various releases of MySQL and
<code class="literal">
InnoDB
</code>
. The default value of
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
is
<code class="literal">
0
</code>
, so that by default there is no limit on the
number of concurrently executing threads.
</p>
<p>
<code class="literal">
InnoDB
</code>
causes threads to sleep only when the
number of concurrent threads is limited. When there is no limit on
the number of threads, all contend equally to be scheduled. That
is, if
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
is
<code class="literal">
0

, the value of
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_sleep_delay">
<code class="literal">
innodb_thread_sleep_delay
</code>
</a>
is
ignored.
</p>
<p>
When there is a limit on the number of threads (when
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
is >
0),
<code class="literal">
InnoDB
</code>
reduces context switching overhead
by permitting multiple requests made during the execution of a
<span class="emphasis">
<em>
single SQL statement
</em>
</span>
to enter
<code class="literal">
InnoDB
</code>
without observing the limit set by
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
. Since
an SQL statement (such as a join) may comprise multiple row
operations within
<code class="literal">
InnoDB
</code>
,
<code class="literal">
InnoDB
</code>
assigns a specified number of
<span class="quote">
“
<span class="quote">
tickets
</span>
”
</span>
that allow a thread to be scheduled
repeatedly with minimal overhead.
</p>
<p>
When a new SQL statement starts, a thread has no tickets, and it
must observe
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
. Once
the thread is entitled to enter
<code class="literal">
InnoDB
</code>
, it is
assigned a number of tickets that it can use for subsequently
entering
<code class="literal">
InnoDB
</code>
to perform row operations. If
the tickets run out, the thread is evicted, and
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
is
observed again which may place the thread back into the
first-in/first-out queue of waiting threads. When the thread is
once again entitled to enter
<code class="literal">
InnoDB
</code>
, tickets
are assigned again. The number of tickets assigned is specified by
the global option
<a class="link" href="innodb-parameters.html#sysvar_innodb_concurrency_tickets">
<code class="literal">
innodb_concurrency_tickets
</code>
</a>
, which
is 5000 by default. A thread that is waiting for a lock is given
one ticket once the lock becomes available.
</p>
<p>
The correct values of these variables depend on your environment
and workload. Try a range of different values to determine what
value works for your applications. Before limiting the number of
concurrently executing threads, review configuration options that
may improve the performance of
<code class="literal">
InnoDB
</code>
on
multi-core and multi-processor computers, such as
<a class="link" href="innodb-parameters.html#sysvar_innodb_adaptive_hash_index">
<code class="literal">
innodb_adaptive_hash_index
</code>

Disk seeks are a huge performance bottleneck. This problem
becomes more apparent when the amount of data starts to grow
so large that effective caching becomes impossible. For
large databases where you access data more or less randomly,
you can be sure that you need at least one disk seek to read
and a couple of disk seeks to write things. To minimize this
problem, use disks with low seek times.

<p>
This means that, for

you symlink the index file and data files from their
usual location in the data directory to another disk
(that may also be striped). This makes both the seek and
read times better, assuming that the disk is not used
for other purposes as well. See

benchmark your application with different stripe sizes.

probably the best option if you have the money for it.
However, you may also have to invest in some
volume-management software to handle it efficiently.

A good option is to vary the RAID level according to how
critical a type of data is. For example, store
semi-important data that can be regenerated on a RAID 0
disk, but store really important data such as host
information and logs on a RAID 0+1 or RAID
<em class="replaceable">
<code>
N

</em>
disk. RAID
<em class="replaceable">
<code>
N
</code>
</em>
can be a problem if you have
many writes, due to the time required to update the parity
bits.

</li>
<li class="listitem">
<p>
You can also set the parameters for the file system that the
database uses:
</p>
<p>
If you do not need to know when files were last accessed
(which is not really useful on a database server), you can
mount your file systems with the
<code class="option">
-o noatime
</code>
option. That skips updates to the last access time in inodes
on the file system, which avoids some disk seeks.
</p>
<p>
On many operating systems, you can set a file system to be
updated asynchronously by mounting it with the
<code class="option">
-o
async
</code>
option. If your computer is reasonably
stable, this should give you better performance without
sacrificing too much reliability. (This flag is on by
default on Linux.)

Using NFS with MySQL
</h4>
</div>
</div>
</div>
<p>
You should be cautious when considering whether to use NFS
with MySQL. Potential issues, which vary by operating system
and NFS version, include the following:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
MySQL data and log files placed on NFS volumes becoming
locked and unavailable for use. Locking issues may occur
in cases where multiple instances of MySQL access the same
data directory or where MySQL is shut down improperly, due
to a power outage, for example. NFS version 4 addresses
underlying locking issues with the introduction of
advisory and lease-based locking. However, sharing a data
directory among MySQL instances is not recommended.
</p>
</li>
<li class="listitem">
<p>
Data inconsistencies introduced due to messages received
out of order or lost network traffic. To avoid this issue,
use TCP with
<code class="literal">
hard

and
<code class="literal">
intr
</code>
mount options.
</p>
</li>
<li class="listitem">
<p>
Maximum file size limitations. NFS Version 2 clients can
only access the lowest 2GB of a file (signed 32 bit
offset). NFS Version 3 clients support larger files (up to
64 bit offsets). The maximum supported file size also
depends on the local file system of the NFS server.
</p>
</li>
</ul>
</div>
<p>
Using NFS within a professional SAN environment or other
storage system tends to offer greater reliability than using
NFS outside of such an environment. However, NFS within a SAN
environment may be slower than directly attached or
bus-attached non-rotational storage.
</p>
<p>
If you choose to use NFS, NFS Version 4 or later is
recommended, as is testing your NFS setup thoroughly before
deploying into a production environment.

19.1.2.2 Setting the Replica Configuration
</h4>
</div>
</div>
</div>
<p>
Each replica must have a unique server ID, as specified by the
<a class="link" href="replication-options.html#sysvar_server_id">
<code class="literal">
server_id
</code>
</a>
system variable. If
you are setting up multiple replicas, each one must have a
unique
<a class="link" href="replication-options.html#sysvar_server_id">
<code class="literal">
server_id
</code>
</a>
value that
differs from that of the source and from any of the other
replicas. If the replica's server ID is not already set, or the
current value conflicts with the value that you have chosen for
the source or another replica, you must change it.
</p>
<p>
The default
<a class="link" href="replication-options.html#sysvar_server_id">
<code class="literal">
server_id
</code>
</a>
value is
1. You can change the
<a class="link" href="replication-options.html#sysvar_server_id">
<code class="literal">
server_id
</code>
</a>
value dynamically by issuing a statement like this:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-sql"><div class="docs-select-all right" id="sa94491431"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token keyword">SET</span> <span class="token keyword">GLOBAL</span> server_id <span class="token operator">=</span> <span class="token number">21</span><span class="token punctuation">;</span></code></pre>
</div>
<p>
Note that a value of 0 for the server ID prevents a replica from
connecting to a source. If that server ID value (which was the
default in earlier releases) was set previously, you must
restart the server to initialize the replica with your new
nonzero server ID. Otherwise, a server restart is not needed
when you change the server ID, unless you make other
configuration changes that require it. For example, if binary
logging was disabled on the server and you want it enabled for
your replica, a server restart is required to enable this.
</p>
<p>
If you are shutting down the replica server, you can edit the
<code class="literal">
[mysqld]
</code>
section of the configuration file to
specify a unique server ID. For example:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-ini"><div class="docs-select-all right" id="sa33631440"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-ini"><span class="token selector">[mysqld]</span>
<span class="token constant">server-id</span><span class="token attr-value"><span class="token punctuation">=</span>21</span></code></pre>
</div>
<p>
Binary logging is enabled by default on all servers. A replica
is not required to have binary logging enabled for replication
to take place. However, binary logging on a replica means that
the replica's binary log can be used for data backups and crash
recovery. Replicas that have binary logging enabled can also be
used as part of a more complex replication topology. For
example, you might want to set up replication servers using this
chained arrangement:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-none"><div class="docs-select-all right" id="sa53971854"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-none">A -> B -> C</code></pre>
</div>
<p>
Here,
<code class="literal">
A
</code>
serves as the source for the replica
<code class="literal">
B
</code>
, and
<code class="literal">
B
</code>
serves as the
source for the replica
<code class="literal">
C
</code>
. For this to work,
<code class="literal">
B
</code>
must be both a source
<span class="emphasis">
<em>
and
</em>
</span>
a replica. Updates received from
<code class="literal">
A
</code>
must be logged by
<code class="literal">
B
</code>
to
its binary log, in order to be passed on to
<code class="literal">
C
</code>
. In addition to binary logging, this
replication topology requires the system variable
<a class="link" href="replication-options-binary-log.html#sysvar_log_replica_updates">
<code class="literal">
log_replica_updates
</code>
</a>
to be
enabled. With replica updates enabled, the replica writes
updates that are received from a source and performed by the
replica's SQL thread to the replica's own binary log.
<code class="literal">
log_replica_updates
</code>
is enabled by default.
</p>
<p>
If you need to disable binary logging or replica update logging
on a replica, you can do this by specifying the
<a class="link" href="replication-options-binary-log.html#option_mysqld_log-bin">
<code class="option">
--skip-log-bin
</code>
</a>
and
<a class="link" href="replication-options-binary-log.html#sysvar_log_replica_updates">
<code class="option">
--log-replica-updates=OFF
</code>
</a>
options for the replica. If you decide to re-enable these
features on the replica, remove the relevant options and restart
the server.

<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
<code class="literal">
FEDERATED
</code>
tables may be replicated to other
replicas, but you must ensure that the replica servers are
able to use the user/password combination that is defined in
the
<code class="literal">
CONNECTION
</code>
string (or the row in the
<code class="literal">
mysql.servers
</code>
table) to connect to the
remote server.
</p>
</li>
</ul>
</div>
<p>
The following items indicate features that the

support:
</p>
<div class="itemizedlist">

</p>
</li>
<li class="listitem">
<p>
A
<code class="literal">
FEDERATED
</code>
table does not support indexes
in the usual sense; because access to the table data is
handled remotely, it is actually the remote table that makes
use of indexes. This means that, for a query that cannot use
any indexes and so requires a full table scan, the server
fetches all rows from the remote table and filters them
locally. This occurs regardless of any
<code class="literal">
WHERE
</code>
or
<code class="literal">
LIMIT
</code>
used with
this
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT
</code>
</a>
statement; these
clauses are applied locally to the returned rows.
</p>
<p>
Queries that fail to use indexes can thus cause poor
performance and network overload. In addition, since returned
rows must be stored in memory, such a query can also lead to
the local server swapping, or even hanging.

</li>
<li class="listitem">
<p>
Care should be taken when creating a
<code class="literal">

This quick-start guide assumes a certain level of familiarity with
MySQL Shell. The following section is a high level overview, see
the MySQL Shell documentation for more information. MySQL Shell
is a unified scripting interface to MySQL Server. It supports
scripting in JavaScript and Python. JavaScript is the default

<p>
After you have installed and started MySQL server, connect
MySQL Shell to the server instance. You need to know the
address of the MySQL server instance you plan to connect to. To
be able to use the instance as a Document Store, the server
instance must have X Plugin installed and you should connect to
the server using X Protocol. For example to connect to the
instance
<code class="literal">

on the default
X Protocol port of 33060 use the network string

If you connect to the instance using classic MySQL protocol, for
example by using the default
<a class="link" href="server-system-variables.html#sysvar_port">
<code class="literal">
port
</code>
</a>
of 3306 instead of the
<a class="link" href="x-plugin-options-system-variables.html#sysvar_mysqlx_port">
<code class="literal">
mysqlx_port
</code>
</a>
, you
<span class="emphasis">
<em>
cannot
</em>
</span>
use the Document Store
functionality shown in this tutorial. For example the
<code class="literal">
db
</code>
global object is not populated. To use
the Document Store, always connect using X Protocol.
</p>
</div>
<p>
If MySQL Shell is not already running, open a terminal window
and issue:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-terminal"><div class="docs-select-all right" id="sa12084534"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-terminal">mysqlsh <em class="replaceable">user</em>@ds1<span class="token punctuation">.</span>example<span class="token punctuation">.</span>com<span class="token punctuation">:</span>33060/world_x</code></pre>
</div>
<p>
Alternatively, if MySQL Shell is already running use the
<code class="literal">
\connect

</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-mysqlsh"><div class="docs-select-all right" id="sa78194857"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-mysqlsh">\connect <em class="replaceable">user</em>@ds1<span class="token punctuation">.</span>example<span class="token punctuation">.</span>com<span class="token punctuation">:</span><span class="token number">33060</span><span class="token operator">/</span>world_x</code></pre>

The MySQL Thread Pool is a MySQL server plugin that extends the
default connection-handling capabilities of the MySQL server to
limit the number of concurrently executing statements/queries
and transactions to ensure that each has sufficient CPU and
memory resources to fulfill its task. For MySQL
8.4, the Thread Pool plugin is included in MySQL Enterprise Edition, a
commercial product.
</p>
<p>
The default thread-handling model in MySQL Server executes
statements using one thread per client connection. As more
clients connect to the server and execute statements, overall
performance degrades. The Thread Pool plugin provides an
alternative thread-handling model designed to reduce overhead
and improve performance. The Thread Pool plugin increases server
performance by efficiently managing statement execution threads
for large numbers of client connections, especially on modern
multi-CPU/Core systems.

The Thread Pool uses a
<span class="quote">
“
<span class="quote">
divide and conquer
</span>
”
</span>
approach to limiting and balancing concurrency. Unlike the
default connection handling of the MySQL Server, the Thread Pool
separates connections and threads, so there is no fixed
relationship between connections and the threads that execute
statements received from those connections. The Thread Pool then
manages client connections within configurable thread groups,
where they are prioritized and queued based on the nature of the
work they were submitted to accomplish.

The MySQL Connection Pool operates on the client side to ensure
that a MySQL client does not constantly connect to and
disconnect from the MySQL server. It is designed to cache idle
connections in the MySQL client for use by other users as they
are needed. This minimizes the overhead and expense of
establishing and tearing down connections as queries are
submitted to the MySQL server. The MySQL Connection Pool has no
visibility as to the query handling capabilities or load of the
back-end MySQL server. By contrast, the Thread Pool operates on
the MySQL server side and is designed to manage the execution of
inbound concurrent connections and queries as they are received
from the client connections accessing the back-end MySQL
database. Because of the separation of duties, the MySQL
Connection Pool and Thread Pool are orthogonal and can be used
independent of each other.

There are a few rules of thumb to consider for optimal Thread
Pool use cases:
</p>
<p>
The MySQL
<a class="link" href="server-status-variables.html#statvar_Threads_running">
<code class="literal">
Threads_running
</code>
</a>
variable keeps track of the number of concurrent statements
currently executing in the MySQL Server. If this variable
consistently exceeds a region where the server won't operate
optimally (usually going beyond 40 for InnoDB workloads), the
Thread Pool should be beneficial, especially in extreme parallel
overload situations.
</p>
<p>
If you are using the
<a class="link" href="innodb-parameters.html#sysvar_innodb_thread_concurrency">
<code class="literal">
innodb_thread_concurrency
</code>
</a>
to
limit the number of concurrently executing statements, you
should find that the Thread Pool solves the same problem, only
better, by assigning connections to thread groups, then queuing
executions based on transactional content, user defined
designations, and so forth.
</p>
<p>
Lastly, if your workload comprises mainly short queries, the
Thread Pool should be beneficial.

Partitioned Table Support
</h4>
<p>
<code class="literal">
DELETE

supports explicit partition selection
using the
<code class="literal">
PARTITION
</code>
clause, which takes a list
of the comma-separated names of one or more partitions or
subpartitions (or both) from which to select rows to be dropped.
Partitions not included in the list are ignored. Given a
partitioned table
<code class="literal">
t
</code>
with a partition named
<code class="literal">
p0
</code>
, executing the statement
<code class="literal">
DELETE
FROM t PARTITION (p0)
</code>
has the same effect on the table
as executing
<a class="link" href="alter-table.html" title="15.1.9 ALTER TABLE Statement">
<code class="literal">
ALTER
TABLE t TRUNCATE PARTITION (p0)
</code>
</a>
; in both cases, all rows
in partition
<code class="literal">
p0
</code>
are dropped.
</p>
<p>
<code class="literal">
PARTITION
</code>
can be used along with a
<code class="literal">
WHERE
</code>
condition, in which case the condition is
tested only on rows in the listed partitions. For example,
<code class="literal">
DELETE FROM t PARTITION (p0) WHERE c < 5
</code>
deletes rows only from partition
<code class="literal">
p0
</code>
for which
the condition
<code class="literal">
c < 5
</code>
is true; rows in any
other partitions are not checked and thus not affected by the
<code class="literal">
DELETE
</code>
.
</p>
<p>
The
<code class="literal">
PARTITION
</code>
clause can also be used in
multiple-table
<code class="literal">
DELETE
</code>
statements. You can use
up to one such option per table named in the
<code class="literal">

Auto-Increment Columns

<p>
If you delete the row containing the maximum value for an

for a
<code class="literal">

WHERE
</code>
clause) in
<a class="link" href="server-system-variables.html#sysvar_autocommit">

</a>
mode, the sequence
starts over for all storage engines except
<code class="literal">

<p>
For

The
<code class="literal">
QUICK
</code>
modifier affects whether index leaves
are merged for delete operations.
<code class="literal">
DELETE QUICK
</code>
is most useful for applications where index values for deleted
rows are replaced by similar index values from rows inserted
later. In this case, the holes left by deleted values are reused.
</p>
<p>
<code class="literal">
DELETE QUICK
</code>
is not useful when deleted values
lead to underfilled index blocks spanning a range of index values
for which new inserts occur again. In this case, use of
<code class="literal">
QUICK
</code>
can lead to wasted space in the index
that remains unreclaimed. Here is an example of such a scenario:
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
Create a table that contains an indexed
<code class="literal">
AUTO_INCREMENT
</code>
column.
</p>
</li>
<li class="listitem">
<p>
Insert many rows into the table. Each insert results in an
index value that is added to the high end of the index.
</p>
</li>
<li class="listitem">
<p>
Delete a block of rows at the low end of the column range
using
<code class="literal">
DELETE QUICK
</code>
.
</p>
</li>
</ol>
</div>
<p>
In this scenario, the index blocks associated with the deleted
index values become underfilled but are not merged with other
index blocks due to the use of
<code class="literal">
QUICK
</code>
. They
remain underfilled when new inserts occur, because new rows do not
have index values in the deleted range. Furthermore, they remain
underfilled even if you later use
<a class="link" href="delete.html" title="15.2.2 DELETE Statement">
<code class="literal">
DELETE
</code>
</a>
without
<code class="literal">
QUICK
</code>
, unless some of the deleted index values
happen to lie in index blocks within or adjacent to the
underfilled blocks. To reclaim unused index space under these
circumstances, use
<a class="link" href="optimize-table.html" title="15.7.3.4 OPTIMIZE TABLE Statement">
<code class="literal">
OPTIMIZE TABLE
</code>
</a>
.
</p>
<p>
If you are going to delete many rows from a table, it might be
faster to use
<code class="literal">
DELETE QUICK
</code>
followed by
<a class="link" href="optimize-table.html" title="15.7.3.4 OPTIMIZE TABLE Statement">
<code class="literal">

index rather than performing many index block merge operations.

When a character set has multiple collations, it might not be
clear which collation is most suitable for a given application. To
avoid choosing an inappropriate collation, perform some
comparisons with representative data values to make sure that a
given collation sorts values the way you expect.

table
contains current stage events. The table stores one row per
thread showing the current status of the thread's most recent
monitored stage event, so there is no system variable for
configuring the table size.

<p>
Of the tables that contain stage event rows,

<code class="literal">
events_stages_current

fundamental. Other tables that contain stage event rows are
logically derived from the current events. For example, the

<code class="literal">
events_stages_history

<code class="literal">

</a>
tables
are collections of the most recent stage events that have
ended, up to a maximum number of rows per thread and globally
across all threads, respectively.
</p>
<p>

MySQL implements two sets of functions using function names

<p>
A loadable function is a way to extend MySQL with a new function
that works like a native (built-in) MySQL function such as
<a class="link" href="mathematical-functions.html#function_abs">
<code class="literal">
ABS()
</code>
</a>
or
<a class="link" href="string-functions.html#function_concat">

Adding a Loadable Function
</a>
.
</p>
<p>
<em class="replaceable">
<code>
function_name
</code>
</em>
is the name that should
be used in SQL statements to invoke the function. The
<code class="literal">
RETURNS
</code>
clause indicates the type of the
function's return value.
<code class="literal">
DECIMAL
</code>
is a legal
value after
<code class="literal">
RETURNS
</code>
, but currently
<code class="literal">
DECIMAL
</code>
functions return string values and
should be written like
<code class="literal">
STRING
</code>
functions.
</p>
<p>
<code class="literal">
IF NOT EXISTS
</code>
prevents an error from
occurring if there already exists a loadable function with the
same name. It does
<span class="emphasis">

</span>
prevent an error
from occurring if there already exists a built-in function
having the same name.
<code class="literal">
IF NOT EXISTS

supported for
<code class="literal">
CREATE FUNCTION

statements. See
<a class="xref" href="function-resolution.html#function-name-resolution" title="Function Name Resolution">
Function Name Resolution
</a>
.
</p>
<p>
The
<code class="literal">
AGGREGATE
</code>
keyword, if given, signifies
that the function is an aggregate (group) function. An aggregate
function works exactly like a native MySQL aggregate function
such as
<a class="link" href="aggregate-functions.html#function_sum">
<code class="literal">
SUM()
</code>
</a>
or
<a class="link" href="aggregate-functions.html#function_count">
<code class="literal">
COUNT()
</code>
</a>
.
</p>
<p>
<em class="replaceable">
<code>
shared_library_name
</code>
</em>
is the base name
of the shared library file containing the code that implements
the function. The file must be located in the plugin directory.
This directory is given by the value of the
<a class="link" href="server-system-variables.html#sysvar_plugin_dir">
<code class="literal">

12.9.7 The utf32 Character Set (UTF-32 Unicode Encoding)
</h3>

</div>

<a class="indexterm" name="idm46045216550592">
</a>
<p>
The
<code class="literal">
utf32
</code>
character set is fixed length (like
<code class="literal">
ucs2
</code>
and unlike
<code class="literal">
utf16
</code>
).
<code class="literal">
utf32
</code>
uses 32 bits for every character,
unlike
<code class="literal">
ucs2
</code>
(which uses 16 bits for every
character), and unlike
<code class="literal">
utf16
</code>
(which uses 16
bits for some characters and 32 bits for others).
</p>
<p>
<code class="literal">
utf32
</code>
takes twice as much space as
<code class="literal">
ucs2
</code>
and more space than
<code class="literal">
utf16
</code>
, but
<code class="literal">
utf32
</code>
has the
same advantage as
<code class="literal">
ucs2
</code>
that it is predictable
for storage: The required number of bytes for
<code class="literal">
utf32
</code>
equals the number of characters times
4. Also, unlike
<code class="literal">
utf16
</code>
, there are no tricks
for encoding in
<code class="literal">
utf32
</code>
, so the stored value
equals the code value.
</p>
<p>
To demonstrate how the latter advantage is useful, here is an
example that shows how to determine a
<code class="literal">
utf8mb4
</code>
value given the
<code class="literal">
utf32
</code>
code value:

MySQL is very forgiving about additions of unassigned Unicode
characters or private-use-area characters. There is in fact only
one validity check for

: No code value
may be greater than
<code class="literal">

this is illegal:

This section discusses the implementation and use of Transport
Layer Security (TLS) to secure network communications in MySQL NDB
Cluster. Topics covered include keys and certificates, key and
certificate life cycles, authentication of certificates, and how
these are reflected in the configuration of the cluster, as well
as NDB Cluster support for the Internet Public Key Infrastructure
(PKI) used to authenticate and encrypt connections between NDB
nodes, and between the NDB management server and its clients.

TLS for NDB Cluster on Linux requires compiled-in support for

failure of a single replication channel. This requires a total of
four replication servers, two source servers on the source cluster
and two replica servers on the replica cluster. For purposes of
the discussion that follows, we assume that unique identifiers are
assigned as shown here:

Setting up replication with two channels is not radically
different from setting up a single replication channel. First, the

<span class="command">

replication source servers must be started, followed by those for
the primary and secondary replicas. The replication processes can
be initiated by issuing the

table contains
information that determines whether to enable monitoring and
historical event logging for new foreground server threads
(threads associated with client connections). This table has a

MySQL client programs may elect to resume a prior SSL session,
provided that the server has the session in its runtime cache.
This section describes the conditions that are favorable for SSL
session reuse, the server variables used for managing and
monitoring the session cache, and the client command-line options
for storing and reusing session data.

<p>
Each full TLS exchange can be costly both in terms of computation
and network overhead, less costly if TLSv1.3 is used. By
extracting a session ticket from an established session and then
submitting that ticket while establishing the next connection, the
overall cost is reduced if the session can be reused. For example,
consider the benefit of having web pages that can open multiple
connections and generate faster.
</p>
<p>
In general, the following conditions must be satisfied before SSL
sessions can be reused:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem">
<p>
The server must keep its session cache in memory.

<li class="listitem">
<p>

</p>
</li>
</ul>
</div>

C applications can use the C API capabilities to enable session
reuse for encrypted connections (see

To create the initial TLS context, the server uses the values
that the context-related system variables have at startup. To
expose the context values, the server also initializes a set of
corresponding status variables. The following table shows the
system variables that define the server's runtime session cache
and the corresponding status variables that expose the currently
active session-cache values.

To reconfigure the SSL session cache at runtime, use this
procedure:
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
Set each cache-related system variable that should be
changed to its new value. For example, change the cache
timeout value from the default (300 seconds) to 600 seconds:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-sql"><div class="docs-select-all right" id="sa8339014"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token prompt">mysql></span> <span class="token keyword">SET</span> <span class="token keyword">GLOBAL</span> ssl_session_cache_timeout <span class="token operator">=</span> <span class="token number">600</span><span class="token punctuation">;</span></code></pre>

The members of each pair of system and status variables may

Client-Side Configuration for SSL Session Reuse
</h4>
</div>
</div>
</div>
<p>
All MySQL client programs are capable of reusing a prior session
for new encrypted connections made to the same server, provided
that you stored the session data while the original connection
was still active. Session data are stored to a file and you
specify this file when you invoke the client again.
</p>
<p>
To store and reuse SSL session data, use this procedure:
</p>
<div class="orderedlist">
<ol class="orderedlist" type="1">
<li class="listitem">
<p>
Invoke
<a class="link" href="mysql.html" title="6.5.1 mysql — The MySQL Command-Line Client">
<span class="command">
<strong>
mysql
</strong>
</span>
</a>
to establish an encrypted
connection to a server running MySQL 8.4.
</p>
</li>
<li class="listitem">
<p>
Use the
<span class="command">
<strong>
ssl_session_data_print
</strong>
</span>
command to
specify the path to a file where you can store the currently
active session data securely. For example:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting one-line language-sql"><div class="docs-select-all right" id="sa95387962"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-sql"><span class="token prompt">mysql></span> ssl_session_data_print <span class="token operator">~</span><span class="token operator">/</span>private<span class="token operator">-</span>dir<span class="token operator">/</span><span class="token keyword">session</span><span class="token punctuation">.</span>txt</code></pre>
</div>
<p>
Session data are obtained in the form of a null-terminated,
PEM encoded ANSI string. If you omit the path and file name,
the string prints to standard output.
</p>
</li>
<li class="listitem">
<p>
From the prompt of your command interpreter, invoke any
MySQL client program to establish a new encrypted connection
to the same server. To reuse the session data, specify the
<a class="link" href="connection-options.html#option_general_ssl-session-data">
<code class="option">

Several conditions may prevent the successful retrieval of
session data. For instance, if the session is not fully
connected, it is not an SSL session, the server has not yet sent
the session data, or the SSL session is simply not reusable.
Even with properly stored session data, the server's session
cache can time out. Regardless of the cause, an error is
returned by default if you specify
<a class="link" href="connection-options.html#option_general_ssl-session-data">
<code class="option">
--ssl-session-data
</code>
</a>
but the
session cannot be reused. For example:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-simple"><div class="docs-select-all right" id="sa27245484"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-simple">mysqlshow <span class="token operator">-</span>u admin <span class="token operator">-</span>p <span class="token operator">--</span>ssl<span class="token operator">-</span>session<span class="token operator">-</span>data<span class="token operator">=</span><span class="token operator">~</span><span class="token operator">/</span>private<span class="token operator">-</span>dir<span class="token operator">/</span>session<span class="token punctuation">.</span>txt

ERROR<span class="token operator">:</span>
<span class="token operator">--</span>ssl<span class="token operator">-</span>session<span class="token operator">-</span>data specified but the session was not reused<span class="token punctuation">.</span></code></pre>
</div>
<p>
To suppress the error message, and to establish the connection
by silently creating a new session instead, specify
<a class="link" href="connection-options.html#option_general_ssl-session-data-continue-on-failed-reuse">
<code class="option">
--ssl-session-data-continue-on-failed-reuse
</code>
</a>
on the command line, along with
<a class="link" href="connection-options.html#option_general_ssl-session-data">
<code class="option">
--ssl-session-data
</code>
</a>
. If the
server's cache timeout has expired, you can store the session
data again to the same file. The default server cache timeout
can be extended (see
<a class="xref" href="reusing-ssl-sessions.html#ssl-session-cache-server-configuration" title="Server-Side Runtime Configuration and Monitoring for SSL Session Reuse">

generated columns. Other index types are not supported. A
secondary index defined on a virtual column is sometimes
referred to as a
<span class="quote">
“
<span class="quote">
virtual index
</span>
”
</span>
.
</p>
<p>
A secondary index may be created on one or more virtual columns
or on a combination of virtual columns and regular columns or
stored generated columns. Secondary indexes that include virtual
columns may be defined as
<code class="literal">
UNIQUE
</code>
.
</p>
<p>
When a secondary index is created on a virtual generated column,
generated column values are materialized in the records of the
index. If the index is a
<a class="link" href="glossary.html#glos_covering_index" title="covering index">
covering index
</a>
(one
that includes all the columns retrieved by a query), generated
column values are retrieved from materialized values in the
index structure instead of computed
<span class="quote">
“
<span class="quote">
on the fly
</span>
”
</span>
.
</p>
<p>
There are additional write costs to consider when using a
secondary index on a virtual column due to computation performed
when materializing virtual column values in secondary index
records during
<a class="link" href="insert.html" title="15.2.7 INSERT Statement">
<code class="literal">
INSERT
</code>
</a>
and
<a class="link" href="update.html" title="15.2.17 UPDATE Statement">
<code class="literal">
UPDATE
</code>
</a>
operations. Even with
additional write costs, secondary indexes on virtual columns may
be preferable to generated
<span class="emphasis">
<em>
stored
</em>
</span>
columns,
which are materialized in the clustered index, resulting in
larger tables that require more disk space and memory. If a
secondary index is not defined on a virtual column, there are
additional costs for reads, as virtual column values must be
computed each time the column's row is examined.
</p>
<p>
Values of an indexed virtual column are MVCC-logged to avoid
unnecessary recomputation of generated column values during
rollback or during a purge operation. The data length of logged
values is limited by the index key limit of 767 bytes for
<code class="literal">
COMPACT
</code>
and
<code class="literal">
REDUNDANT
</code>
row
formats, and 3072 bytes for
<code class="literal">
DYNAMIC
</code>
and
<code class="literal">
COMPRESSED
</code>
row formats.
</p>
<p>
Adding or dropping a secondary index on a virtual column is an
in-place operation.

references such a column indirectly, you can define a
generated column that extracts the information that should be
indexed, then create an index on the generated column, as
shown in this example:

Note
</div>
<p>
In MySQL 8.4, the
<code class="literal">
validate_password
</code>
plugin was reimplemented
as the
<code class="literal">
validate_password
</code>
component. The
<code class="literal">
validate_password
</code>
plugin is deprecated;
expect it to be removed in a future version of MySQL.
</p>
</div>
<p>
MySQL installations that currently use the
<code class="literal">
validate_password
</code>
plugin should make the
transition to using the
<code class="literal">
validate_password
</code>
component instead. To do so, use the following procedure. The
procedure installs the component before uninstalling the plugin,
to avoid having a time window during which no password
validation occurs. (The component and plugin can be installed
simultaneously. In this case, the server attempts to use the
component, falling back to the plugin if the component is
unavailable.)
</p>
<div class="orderedlist">

</div>
</li>
<li class="listitem">
<p>
Test the
<code class="literal">

ensure that it works as expected. If you need to set any

<em class="replaceable">

</em>
</code>
system variables, you can do so at runtime using
<code class="literal">
SET

</code>
. (Any option file changes that must be made
are performed in the next step.)
</p>
</li>
<li class="listitem">
<p>
Adjust any references to the plugin system and status
variables to refer to the corresponding component system and
status variables. Suppose that previously you had configured
the plugin at startup using an option file like this:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-ini"><div class="docs-select-all right" id="sa40389639"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-ini"><span class="token selector">[mysqld]</span>
<span class="token constant">validate-password</span><span class="token attr-value"><span class="token punctuation">=</span>FORCE_PLUS_PERMANENT</span>
<span class="token constant">validate_password_dictionary_file</span><span class="token attr-value"><span class="token punctuation">=</span>/usr/share/dict/words</span>
<span class="token constant">validate_password_length</span><span class="token attr-value"><span class="token punctuation">=</span>10</span>
<span class="token constant">validate_password_number_count</span><span class="token attr-value"><span class="token punctuation">=</span>2</span></code></pre>
</div>
<p>
Those settings are appropriate for the plugin, but must be
modified to apply to the component. To adjust the option
file, omit the
<a class="link" href="validate-password-options-variables.html#option_mysqld_validate-password">
<code class="option">
--validate-password
</code>
</a>
option
(it applies only to the plugin, not the component), and
modify the system variable references from no-dot names
appropriate for the plugin to dotted names appropriate for
the component:
</p>
<div class="copytoclipboard-wrapper">
<pre class="programlisting language-ini"><div class="docs-select-all right" id="sa98755711"><div class="copy-help left">Press ⌘+C to copy</div> <div class="right"><button class="clipboard-btn" title="Copy to Clipboard"><span class="icon-clipboard"></span></button></div></div><code class="language-ini"><span class="token selector">[mysqld]</span>
<span class="token constant">validate_password.dictionary_file</span><span class="token attr-value"><span class="token punctuation">=</span>/usr/share/dict/words</span>
<span class="token constant">validate_password.length</span><span class="token attr-value"><span class="token punctuation">=</span>10</span>
<span class="token constant">validate_password.number_count</span><span class="token attr-value"><span class="token punctuation">=</span>2</span></code></pre>
</div>
<p>
Similar adjustments are needed for applications that refer
at runtime to
<code class="literal">
validate_password
</code>
plugin
system and status variables. Change the no-dot plugin
variable names to the corresponding dotted component
variable names.
</p>
</li>
<li class="listitem">
<p>
Uninstall the
<code class="literal">

remove it from the file.

The time reported is elapsed time on the client end, not CPU
time on the server end. It is advisable to execute
<a class="link" href="information-functions.html#function_benchmark">
<code class="literal">
BENCHMARK()

</a>
several times, and
to interpret the result with regard to how heavily loaded the
server machine is.

<p>
<a class="link" href="information-functions.html#function_benchmark">
<code class="literal">
BENCHMARK()

</a>
is intended for
measuring the runtime performance of scalar expressions, which
has some significant implications for the way that you use it
and interpret the results:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" style="list-style-type: circle; ">
<li class="listitem">
<p>
Only scalar expressions can be used. Although the
expression can be a subquery, it must return a single
column and at most a single row. For example,
<a class="link" href="information-functions.html#function_benchmark">
<code class="literal">
BENCHMARK(10, (SELECT * FROM
t))

fails if the table

Executing a

in terms of the
amount of overhead involved. The two have very different
execution profiles and you should not expect them to take
the same amount of time. The former involves the parser,
optimizer, table locking, and runtime evaluation
<em class="replaceable">
<code>

times each. The latter
involves only runtime evaluation
<em class="replaceable">
<code>
N

times, and all the other
components just once. Memory structures already allocated
are reused, and runtime optimizations such as local
caching of results already evaluated for aggregate
functions can alter the results. Use of
<a class="link" href="information-functions.html#function_benchmark">
<code class="literal">
BENCHMARK()

thus measures
performance of the runtime component by giving more weight
to that component and removing the

The example illustrates that although the client specified a
user name of
<code class="literal">
davida
</code>
(as indicated by the
value of the
<a class="link" href="information-functions.html#function_user">
<code class="literal">

function),
the server authenticated the client using an anonymous user
account (as seen by the empty user name part of the
<a class="link" href="information-functions.html#function_current-user">
<code class="literal">
CURRENT_USER()
</code>
</a>
value). One way
this might occur is that there is no account listed in the
grant tables for
<code class="literal">

</p>
<p>
Within a stored program or view,
<a class="link" href="information-functions.html#function_current-user">

returns the
account for the user who defined the object (as given by its
<code class="literal">

<code class="literal">
SQL SECURITY INVOKER
</code>
characteristic. In the
latter case,
<a class="link" href="information-functions.html#function_current-user">
<code class="literal">
CURRENT_USER()
</code>
</a>
returns the object's invoker.
</p>
<p>
Triggers and events have no option to define the
<code class="literal">
SQL

</code>
characteristic, so for these objects,
<a class="link" href="information-functions.html#function_current-user">
<code class="literal">

If you are using
<code class="literal">

rows are in the full result set. However, this is faster than
running the query again without
<code class="literal">

,
because the result set need not be sent to the client.

SQL_CALC_FOUND_ROWS

<a class="link" href="information-functions.html#function_found-rows">
<code class="literal">
FOUND_ROWS()

can be useful in
situations when you want to restrict the number of rows that a
query returns, but also determine the number of rows in the
full result set without running the query again. An example is
a Web script that presents a paged display containing links to
the pages that show other sections of a search result. Using
<a class="link" href="information-functions.html#function_found-rows">
<code class="literal">
FOUND_ROWS()

the changed value is seen by statements that follow the

The ID that was generated is maintained in the server on a

clients, even if they generate

behavior ensures that each client can retrieve its own ID
without concern for the activity of other clients, and without
the need for locks or transactions.

<p>
The value of

The
<a class="link" href="update.html" title="15.2.17 UPDATE Statement">
<code class="literal">

</a>
statement
increments the sequence counter and causes the next call
to
<a class="link" href="information-functions.html#function_last-insert-id">
<code class="literal">
LAST_INSERT_ID()
</code>
</a>
to
return the updated value. The
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT
</code>
</a>
statement retrieves
that value. The
<a class="ulink" href="/doc/c-api/8.4/en/mysql-insert-id.html" target="_top">
<code class="literal">
mysql_insert_id()
</code>
</a>
C API
function can also be used to get the value. See
<a class="ulink" href="/doc/c-api/8.4/en/mysql-insert-id.html" target="_top">
mysql_insert_id()
</a>
.
</p>
</li>
</ol>

<p>
You can generate sequences without calling
<a class="link" href="information-functions.html#function_last-insert-id">
<code class="literal">
LAST_INSERT_ID()
</code>
</a>
, but the
utility of using the function this way is that the ID value is
maintained in the server as the last automatically generated
value. It is multi-user safe because multiple clients can
issue the
<a class="link" href="update.html" title="15.2.17 UPDATE Statement">
<code class="literal">
UPDATE
</code>
</a>
statement and
get their own sequence value with the
<a class="link" href="select.html" title="15.2.13 SELECT Statement">
<code class="literal">
SELECT
</code>
</a>
statement (or
<a class="ulink" href="/doc/c-api/8.4/en/mysql-insert-id.html" target="_top">
<code class="literal">
mysql_insert_id()
</code>
</a>
), without
affecting or being affected by other clients that generate
their own sequence values.
</p>
<p>
Note that
<a class="ulink" href="/doc/c-api/8.4/en/mysql-insert-id.html" target="_top">
<code class="literal">
mysql_insert_id()
</code>
</a>
is
only updated after
<a class="link" href="insert.html" title="15.2.7 INSERT Statement">

INSERT
</code>
</a>
and
<a class="link" href="update.html" title="15.2.17 UPDATE Statement">
<code class="literal">
UPDATE

</a>
statements, so you
cannot use the C API function to retrieve the value for

It is not practical to list all the instruments because
there are hundreds of them.

Next, for every table in the query, we estimate the cost of, and

We need to find an optimal order for the tables. Normally, greedy
search is used, but since the statement uses a straight join, only
the requested order is explored, and one or more access methods
are selected. As shown in this portion of the trace, we can choose
a table scan:

<p>
When you add an
<code class="literal">
AUTO_INCREMENT
</code>
column, column
values are filled in with sequence numbers automatically. For
<code class="literal">
MyISAM
</code>
tables, you can set the first sequence
number by executing
<code class="literal">
SET
INSERT_ID=
<em class="replaceable">
<code>
value
</code>
</em>
</code>
before
<a class="link" href="alter-table.html" title="15.1.9 ALTER TABLE Statement">
<code class="literal">
ALTER TABLE
</code>
</a>
or by using the
<code class="literal">
AUTO_INCREMENT=
<em class="replaceable">
<code>
value
</code>
</em>
</code>
table option.
</p>
<p>
With
<code class="literal">
MyISAM
</code>
tables, if you do not change the
<code class="literal">
AUTO_INCREMENT
</code>
column, the sequence number is
not affected. If you drop an
<code class="literal">
AUTO_INCREMENT
</code>
column and then add another
<code class="literal">
AUTO_INCREMENT
</code>
column, the numbers are resequenced beginning with 1.
</p>
<p>
When replication is used, adding an
<code class="literal">
AUTO_INCREMENT
</code>
column to a table might not
produce the same ordering of the rows on the replica and the
source. This occurs because the order in which the rows are
numbered depends on the specific storage engine used for the
table and the order in which the rows were inserted. If it is
important to have the same order on the source and replica, the
rows must be ordered before assigning an
<code class="literal">
AUTO_INCREMENT
</code>
number. Assuming that you want
to add an
<code class="literal">
AUTO_INCREMENT
</code>
column to the table
<code class="literal">
t1
</code>
, the following statements produce a new
table
<code class="literal">
t2
</code>
identical to
<code class="literal">

</code>
but with an
<code class="literal">
AUTO_INCREMENT
</code>
column:

</code>
method works by filtering a query to include only the records to
be updated and then applying the operations you specify to those
records.

<p>
To replace a city name in the city table, pass to the
<code class="literal">

</code>
method the city name to locate
and replace. The following example replaces the city Peking with
Beijing.
