Managing user privileges in MySQL is essential for maintaining security and ensuring that users can only access data that they are permitted to. This includes granting and revoking permissions for various database operations.
To manage user privileges, you can use the following SQL commands:
-- Granting privileges
GRANT SELECT, INSERT ON database_name.* TO 'username'@'host';
-- Revoking privileges
REVOKE INSERT ON database_name.* FROM 'username'@'host';
-- Viewing privileges
SHOW GRANTS FOR 'username'@'host';
In this example:
GRANT
command is used to assign specific privileges.REVOKE
command is used to remove specific privileges.SHOW GRANTS
command is used to display the current privileges of a user.
