Display all grants of a specific user in MySQL
Let us first display all usernames along with host name −
mysql> select user,host from MySQL.user;
This will produce the following output −
+------------------+-----------+ | user | host | +------------------+-----------+ | Bob | % | | Charlie | % | | Robert | % | | User2 | % | | mysql.infoschema | % | | mysql.session | % | | mysql.sys | % | | root | % | | @UserName@ | localhost | | Adam | localhost | | Adam Smith | localhost | | Chris | localhost | | David | localhost | | James | localhost | | John | localhost | | John Doe | localhost | | Michael | localhost | | Mike | localhost | | User1 | localhost | | am | localhost | | hbstudent | localhost | | mysql.infoschema | localhost | | mysql.session | localhost | +------------------+-----------+ 23 rows in set (0.00 sec)
Here is the query to view all grants of a specific user −
mysql> show grants for 'John'@'localhost';
This will produce the following output −
+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Grants for John@localhost | +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, SHUTDOWN, PROCESS, FILE, REFERENCES, INDEX, ALTER, SHOW DATABASES, SUPER, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER, CREATE TABLESPACE, CREATE ROLE, DROP ROLE ON *.* TO `John`@`localhost` | | GRANT BACKUP_ADMIN,BINLOG_ADMIN,CONNECTION_ADMIN,ENCRYPTION_KEY_ADMIN,GROUP_REPLICATION_ADMIN,PERSIST_RO_VARIABLES_ADMIN,REPLICATION_SLAVE_ADMIN,RESOURCE_GROUP_ADMIN,RESOURCE_GROUP_USER,ROLE_ADMIN,SET_USER_ID,SYSTEM_VARIABLES_ADMIN,XA_RECOVER_ADMIN ON *.* TO `John`@`localhost` | +----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ 2 rows in set (0.07 sec)
