Which command grants or removes other users’ privileges in MySQL?

The command that grants or removes other users' privileges in MySQL is the GRANT and REVOKE command.

Here's how to use them:

1. GRANT Command: This command is used to give users access to the database. The syntax is as follows:

GRANT privilege_type ON database_name.table_name TO 'username'@'localhost';

In this command, privilege_type is the type of privilege you want to grant (like SELECT, INSERT, UPDATE, DELETE, etc.), database_name is the name of your database, and table_name is the name of your table.

2. REVOKE Command: This command is used to take back the access given to users. The syntax is as follows:

REVOKE privilege_type ON database_name.table_name FROM 'username'@'localhost';

In this command, privilege_type is the type of privilege you want to revoke, database_name is the name of your database, and table_name is the name of your table.

Remember to replace 'username'@'localhost' with the actual username and host where the user is connecting from. Also, after executing GRANT or REVOKE commands, you should run the FLUSH PRIVILEGES; command to make sure the changes take effect.
