And how to handle & perform insert,up upda, delete	What is PostgreSQL Json Data Type	tutorialdba.com	2021.04	[ { "text": "\nwhat is JSON ?\n\n\n* It is one of the data type in postgres.\n* Json + PostgreSQL =NoSQL\n* JSON STANDS FOR JavaScript Object Notation\n* JSON data types stored value is valid according to the JSON rules.\n* JSON data types are for storing JSON data as multi-level, dynamically structured object graphs.\n* serialised object is stored in a text column. The json type takes care of deserialising it back to object graph while reading values from that column.\n* The main usage of JSON is to transport data between a server and web application. Unlike other formats, JSON is human-readable text.\n* PostgreSQL supports JSON data type since version 9.2.\n* It provides many functions and operators for manipulating JSON data.\n\n\nThere are two JSON data types: \n\n1.json \n\n2.jsonb\n\n\n* The json data type stores an exact copy of the input text.\n* jsonb data is stored in a decomposed binary format\n* jsonb Insertion makes it slightly slower to input due to added conversion overhead.\n* jsonb also supports indexing\n* JSONB does not keep duplicate object keys. If duplicate keys are specified in the input, only the last value is kept.\n\n\nPRACTICAL 1. CREATING SIMPLE JSON TABLE: \n\n \n\n\n\n```\npostgres=# CREATE TABLE SALES (\n ID INT NOT NULL PRIMARY KEY,\n SALES\\_INFO json NOT NULL\n);\n```\n\nFrom above Sales table consists of two columns:\n\n\n* The id column is the primary key column that identifies the sales id.\n* The sales\\_info column stores the data in the form of JSON data types.\n\n\n--Describe the sales table using \\d \n\n \n\n\n\n```\npostgres=# \\d sales\n Table \"public.sales\"\n Column \| Type \| Modifiers \n------------+---------+-----------\n id \| integer \| not null\n sales\\_info \| json \| not null\nIndexes:\n \"sales\\_pkey\" PRIMARY KEY, btree (id) \n```\n\nPRACTICAL 2. INSERTING JSON DATA ON SALES TABLE: \n\n \n\n\n\n```\nINSERT INTO SALES VALUES\n (1,'{ \"customer\": \"NIJAM\", \"PRODUCTS\": {\"product\\_name\": \"choclate\",\"total\\_item\": 6}}'\n );\n\nINSERT INTO SALES VALUES\n (2,'{ \"customer\": \"ABU\", \"PRODUCTS\": {\"product\\_name\": \"badam\",\"total\\_item\": 5}}'\n );\n\nINSERT INTO SALES VALUES\n (3,'{ \"customer\": \"UMAR\", \"PRODUCTS\": {\"product\\_name\": \"mobile\",\"total\\_item\": 1}}'\n ); \n```\n\n--List down the sales table \n\n \n\n\n\n```\npostgres=# select * from sales;\n id \| sales\\_info \n----+----------------------------------------------------------------------------------\n 1 \| { \"customer\": \"NIJAM\", \"PRODUCTS\": {\"product\\_name\": \"choclate\",\"total\\_item\": 6}}\n 2 \| { \"customer\": \"ABU\", \"PRODUCTS\": {\"product\\_name\": \"badam\",\"total\\_item\": 5}}\n 3 \| { \"customer\": \"UMAR\", \"PRODUCTS\": {\"product\\_name\": \"mobile\",\"total\\_item\": 1}}\n(3 rows) \n```\n\n--list down the json column only \n\n \n\n\n\n```\npostgres=# select sales\\_info from sales;\n sales\\_info \n----------------------------------------------------------------------------------\n { \"customer\": \"NIJAM\", \"PRODUCTS\": {\"product\\_name\": \"choclate\",\"total\\_item\": 6}}\n { \"customer\": \"ABU\", \"PRODUCTS\": {\"product\\_name\": \"badam\",\"total\\_item\": 5}}\n { \"customer\": \"UMAR\", \"PRODUCTS\": {\"product\\_name\": \"mobile\",\"total\\_item\": 1}}\n(3 rows) \n```\n\n--List down the id column only for understanding purposes. \n\n \n\n\n\n```\npostgres=# select id from sales;\n id \n----\n 1\n 2\n 3\n(3 rows) \n```\n\nDeleting json objects: \n\n \n\n\n\n```\npostgres=# select * from sales;\n id \| sales\\_info \n----+-------------------------------------------------------------------------------\n 2 \| { \"customer\": \"ABU\", \"PRODUCTS\": {\"product\\_name\": \"badam\",\"total\\_item\": 5}}\n 3 \| { \"customer\": \"UMAR\", \"PRODUCTS\": {\"product\\_name\": \"mobile\",\"total\\_item\": 1}}\n 4 \| { \"customer\": \"junaith\", \"PRODUCTS\": {\"product\\_name\": \"pen\",\"total\\_item\": 8}}\n 7 \| { \"customer\": \"daniel\", \"PRODUCTS\": {\"product\\_name\": \"car\",\"total\\_item\": 8}}\n 8 \| { \"customer\": \"daniel\", \"PRODUCTS\": {\"product\\_name\": \"car\",\"total\\_item\": 8}}\n(5 rows)\n\npostgres=# delete from sales where sales\\_info ->'PRODUCTS'->>'total\\_item'='8';\nDELETE 3\npostgres=# select * from sales; \n id \| sales\\_info \n----+-------------------------------------------------------------------------------\n 2 \| { \"customer\": \"ABU\", \"PRODUCTS\": {\"product\\_name\": \"badam\",\"total\\_item\": 5}}\n 3 \| { \"customer\": \"UMAR\", \"PRODUCTS\": {\"product\\_name\": \"mobile\",\"total\\_item\": 1}}\n(2 rows) \n```\n\n \n\n\nPRACTICAL 3.HOW TO QUERYING & FILTERING JSON DATA: \n\nthe two operators -> and ->> to help you query JSON data.\n\n\n* -> will return the attribute as a JSON object key(original JSON type).\n* ->> will return the property as integer or text (the parsed form of the attribute).\n\n\n--See the below example first two query did'nt specify column name that is why it showing ?column? after that i specified the column name as customer\\_name \n\n \n\n\n\n```\npostgres=# select sales\\_info -> 'customer' from sales;\n ?column? \n----------\n \"NIJAM\"\n \"ABU\"\n \"UMAR\"\n(3 rows)\n\npostgres=# select sales\\_info ->> 'customer' from sales;\n ?column? \n----------\n NIJAM\n ABU\n UMAR\n(3 rows)\n\npostgres=# select sales\\_info ->> 'customer' as customer\\_name from sales;\n customer\\_name \n---------------\n NIJAM\n ABU\n UMAR\n(3 rows)\n\npostgres=# select sales\\_info -> 'PRODUCTS' from sales; \n ?column? \n----------------------------------------------\n {\"product\\_name\": \"choclate\",\"total\\_item\": 6}\n {\"product\\_name\": \"badam\",\"total\\_item\": 5}\n {\"product\\_name\": \"mobile\",\"total\\_item\": 1} \n```\n\n* Using -> operator returns a JSON object, you can chain it with the operator ->> to retrieve a specific node.\n* JSON IS CASESENSITIVE DEFAULTY, from below example first i try to retrieve the data using \"products\"(lowercase) that is why it showed empty value after that i chaneged \"PRODUCTS\"(UPPER CASE) then it showing values.\n\n\n\n```\npostgres=# select sales\\_info -> 'products' ->>'product\\_name' from sales;\n ?column? \n----------\n \n \n \n(3 rows)\n\n\npostgres=# select sales\\_info -> 'PRODUCTS' ->'product\\_name' from sales;\n ?column? \n------------\n \"choclate\"\n \"badam\"\n \"mobile\"\n(3 rows)\n\npostgres=# select sales\\_info -> 'PRODUCTS' ->>'product\\_name' from sales;\n ?column? \n----------\n choclate\n badam\n mobile\n(3 rows \n```\n\nFROM above example First sales\\_info -> 'PRODUCTS' returns as JSON objects.

How to create Postgresql database in real time production environment ?	tutorialdba.com	2020.40	[ { "text": "\nBefore creating database you have to create tablespace and then you have to give right tablespace name for database Creation \n\n\nAnd before creating tablespace you have to check with partion or disk space availability it's a prerequest for Postgresql tablespace creation\n\n\nHere given Following steps for creating tablespace & Database in Postgresql environment system.\n\n\nYou have to follow given steps only for Postgresql database creation & tablespace Creation.\n\n\nHere am performed simple steps of Postgresql Database restoring to some other new server & before that what prerequest want to follow for the postgresql Database restoring & Everything am mentioned here.\n\n\nChecking the postgreSQL server status Before restoring :\n\n\n\n```\ncd C:\\Program Files\\edb\\enterprincedb\\as9.6\\bin pg\\_ctl -D \"C:\\Program Files\\edb\\enterprincedb\\as9.6\\data\" status\n```\n\nConnecting the database :\n\n\n\n```\ncd C:\\Program Files\\edb\\enterprincedb\\as9.6\\bin\npsql -U enterprisedb -d edb\n```\n\nChecking the tablespace & database whether already exist with same name in our server : \n\nFOR TABLESPACE :-\n\n\n\n```\nSELECT spcname FROM pg\\_tablespace;\n```\n\nThe psql program's \\db meta-command is also useful for listing the existing tablespaces.\n\n\nFOR DATABASE :-\n\n\n\n```\nSELECT datname FROM pg\\_database;\n```\n\nThe psql program's \\l meta-command is also useful for listing the existing databse.\n\n\nCreating tablespace :\n\n\n\n```\nCREATE TABLESPACE \"HealthCraft\\_LC\" LOCATION 'D:\\HealthCraft\\_LC';\nCREATE TABLESPACE \"HealthCraft\\_DC\" LOCATION 'D:\\HealthCraft\\_DC';\n```\n\nBefore creating tablespace you have to check the server available space and available partition this is one of the prerequest as well.\n\n\nCreating Database :\n\n\n\n```\nCREATE DATABASE \"HealthCraft\\_LC\" TABLESPACE \"HealthCraft\\_LC\";\nCREATE DATABASE \"HealthCraft\\_DC\" TABLESPACE \"HealthCraft\\_DC\";\n\n```\n\nBefore Restoring Database you have to restore the roles other wise you will get roles does not exist error\n\n\nTaking postgres Roles only backup :\n\n\n\n```\npg\\_dumpall -h localhost -p 5432 U enterprisedb -v --roles-only -f \"/path/to/Preprod\\_roles\\_01012019.sql\"\n\n```\n\nTaking

\"D:\\tutorialdba\\Preprod\\_roles\\_01012019.sql\"\n```\n\nRestoring the postgresql database dump by using psql utility otherwise if your dump is custom format means you have to use pg\\_restore utility for database restoration :\n\n\n\n```\npsql -U enterprisedb -d \"HealthCraft\\_LC\" -f \"D:\\tutorialdba\\HealthCraft\\_LC\\_preprod\\_01012019.sql\"\npsql -U enterprisedb -d \"HealthCraft\\_DC\" -f \"D:\\tutorialdba\\HealthCraft\\_DC\\_preprod\\_01012019.sql\"\n```\n\nelse you can use \\i at postgres SQL console (if dump is plain format):\n\n\n\n```\npsql -U enterprisedb -d HealthCraft\\_LC\n\\i D:\\HealthCraft\\_LC\\_preprod\\_01012019.sql\n```\n\nConnect the other(HealthCraft\\_DC) DB the restore the appropriate dump of HealthCraft\\_DC database\n\n\n\n```\n\\c HealthCraft\\_DC\n\\i D:\\HealthCraft\\_DC\\_preprod\\_01012019.sql\n```\n\nTo Dropping the postgres database :\n\n\n\n```\ndrop DATABASE \"HealthCraft\\_LC\";\nERROR: database \"HealthCraft\\_LC\" is being accessed by other users\nDETAIL: There are 2 other sessions using the database.\n```\n\nFirst of all you have to kill the connected session by using pg\\_terminate\\_backend\n\n\n\n```\nSELECT pg\\_terminate\\_backend(pg\\_stat\\_activity.pid) FROM pg\\_stat\\_activity WHERE pg\\_stat\\_activity.datname = 'HealthCraft\\_LC' AND pid <>

e68eb97c7ad39a019980341c8f5cb971	how to optimize and repair MySQL databases and monitoring of your MySQL server including CPU/RAM	MySQL Maintenance Tasks	tutorialdba.com	2020.45	[ { "text": "\nFrom time to time, MySQL 5.1 databases need a little house keeping. We found our production DB had a hard time running a simple join query between two tables with about 400k rows. It was taking between 30 and 100 seconds to run. On QA however, it was taking 58 milliseconds. The columns involved were already indexed. Thankfully it wasn’t impacting our users, but it still bugged me. The solution was simple, just run some cleanup commands. After the cleanup, on the live server the same query took just 4.8 milliseconds – that’s more like it!\n\n\nSummary of solution:\n\n\n1. Backup database\n2. Check\n3. Optimize\n4. Analyze\n\n\n\n```\n$ mysqldump -u root -p --create-options --routines --triggers dbname > ./db.dmp\n# note these cause LOCKS, so be careful on your production server!\n$ mysqlcheck -u root -p --check --databases dbname\n$ mysqlcheck -u root -p --optimize --databases dbname\n$ mysqlcheck -u root -p --analyze --databases dbname\n```\n\n \n\n\nComplete details about each step:\n\n\n1) First make database backup with mysqldump: \n\nDon’t forget the argument –routines if you have stored procedures or functions and –triggers if using triggers:\n\n\n\n```\n$ mysqldump -u root -p --create-options --routines --triggers dbname > ./db.dmp\n# copy to another server\n$ scp ./db.dmp user@somehost:~/\n```\n\nFor bonus points, actually restore the database on another system to make sure you have a valid backup.\n\n\nThis step may be impractical if the database is huge. In that case you are probably already using replication and have a backup system worked out.\n\n\n2) Check: \n\nChecks table for integrity errors. \n\n<http://dev.mysql.com/doc/refman/5.1/en/check-table.html>\n\n\nTo check a single table:\n\n\n\n```\nmysql> CHECK TABLE {table name};\n```\n\nTo check all tables in a database, from command line:\n\n\n\n```\n$ mysqlcheck -u root -p --check --databases dbname\n```\n\nThis seems like a really smart thing to do on a regular basis.\n\n\n3) Optimize:\n\n\nLike a defrag operation, the optimize tables command reclaims unused space. At least, that is what it does for MyISAM. With InnoDB it basically runs an ALTER TABLE statement that changes nothing but tells MySQL to rebuild the table and its indexes. \n\n<http://dev.mysql.com/doc/refman/5.1/en/optimize-table.html>\n\n\nTo optimize a single table:\n\n\n\n```\nmysql> OPTIMIZE TABLE {table name};\n```\n\nTo optimize all tables in a database, from command line:\n\n\n\n```\n$ mysqlcheck -u root -p --optimize --databases dbname\n```\n\nIf you get “Table does not support optimize, doing recreate + analyze instead”, that is normal for InnoDB.\n\n\n4) Analyze:\n\n\nAnalyze rebuilds and optimizes the performance of indexes, specially it rebuilds the key distribution. If you have a slow running query but indexes are in place, it might be time to run this. A read lock goes into effect while this is running. If you have only InnoDB tables, this is already taken care of by Optimize.\n\n\n<http://dev.mysql.com/doc/refman/5.1/en/analyze-table.html>\n\n\nTo analyze a single table:\n\n\n\n```\nmysql> ANALYZE TABLE {table name};\n```\n\nTo analyze all tables in a database, from command line:\n\n\n\n```\n$ mysqlcheck -u root -p --analyze --databases dbname\n```\n\nWith InnoDB and ANALYZE TABLE, there are some oddities.

When problems do arise, this step will help minimize the impact of the problem on the server and data. The mysqlcheck binary program can be used to perform most of these checks. The mysqlcheck program can be used to perform database table consistency checks, table optimization, table analysis, or table repair by passing different arguments to the CLI.\n\n\nTIP: you can create renamed binary copies if the mysqlcheck OR use symbolic links to make calls to the CLI more intuitive. This is because there is a special feature in the code that permits the default behavior of the CLI to change when the file or link is named in a certain fashion. \n\n\nYou can achieve this behavior by:\n\n\n\n```\ncp mysqlcheck mysqlrepair\ncp mysqlcheck mysqloptimize\ncp mysqlcheck mysqlanalyze\n```\n\nOR\n\n\n\n```\nln -s mysqlcheck mysqlrepair\nln -s mysqlcheck mysqloptimize\nln -s mysqlcheck mysqlanalyze\n```\n\nIt is reccommended that this CLI be added to the crontab of the UNIX user account that mysql runs under. \n\n\nCreate a ~/.my.cnf file with login credentials so that the MySQL CLIs can run non-interactively in cron and be able to authenticate.\n\n\n\n```\n[client]\nuser=myuser\npassword=myuserpassword\n```\n\nProtect the file by tightening the UNIX file permissions so that only the UNIX user and/or root may view the file, since it has a password in clear text.\n\n\n\n```\nchmod 600 ~/.my.cnf\nls -lta .my.cnf\n-rw------- 1 mysql mysql 37 2008-12-14 12:01 .my.cnf\n```\n\nAdd the following to the crontab of the UNIX user (in most cases mysql) that MySQL runs under:\n\n\n\n```\n0 0 * * 0 /usr/local/mysql/bin/mysqlcheck --all-databases --check-only-changed --silent\n```\n\nWhen a table is being checked by mysqlcheck, it cannot be updated. So, performing mysqlcheck on large tables should be used at your discretion. It may not make sense to perform mysqlcheck on large tables if you cannot afford the table to be unavailable for updates.\n\n\nAlternatively, you could create the .my.cnf in the /root directory on Linux systems, and place the job into the /etc/cron.daily directory. On Fedora 10, I placed the .my.cnf file in the /root directory. An executable shell script with the mysqlcheck command was placed in the /etc/cron.daily directory. The /etc/crontab script on linux calls a run-parts script which runs all scripts it finds in the /etc/cron.daily, /etc/cron.hourly, /etc/cron.weekly, and /etc/cron.monthly directories.\n\n\n", "name": "", "is_accepted": false } ]
