1) GRANT Command:-
The GRANT command is used to grant permission to the users to access the privilege of the database system.
If you are a database administrator and you want to restrict the user accessibility such as one who only view the data or may only update the data or may one who has full control of the database. You can give the privilege permission to the users as you wish.
The privileges combinationS are such as
- SELECT
- INSERT
- UPDATE
- DELETE
- ALTER
- ALL

If you want to grant SELECT, UPDATE, and DELETE privileges on a table named customer to a database user name Akash. The syntax is as follows:
GRANT SELECT, UPDATE, DELETE ON customer TO Akash;
Example-2:
If you want to grant all privileges to database users Akash on the same table (customer). The syntax looks like this:
GRANT ALL ON customer TO Akash;
2) REVOKE Command:

If you granted the privilege permission to the users on any table and you want to return permission from the database users at that time you need to run REVOKE command.
You can withdraw any of the privileges such as SELECT, INSERT, UPDATE, DELETE, ALTER, or ALL using this command.
