What is DCL?
DCL stands for Data Control Language. It is a type of SQL command that allows performing some work on the database. The work is completed using this command related to rights, permission and other controls of the database system.
It is used to grant permission to other users to access the privileges of the database system such as only insert the data, view the data, update, delete, etc. And also withdraw the granted user’s privilege permissions.
This is the most useful command of SQL. This command deals with the security of user accessibility.
The DCL has a couple of commands which are discussed below.
What are DCL commands?
DCL commands are nothing it is a statement that is used to perform the work related to the rights, permissions and other control of the database system.
As we know that every work has been done on the database by using the commands. It offers only two commands which are written below.
- GRANT Command.
- REVOKE Command.
Note: The SQL commands are not case sensitive. You can write the command in both capital and small letters. But I recommend writing all the DCL or SQL commands in capital letters.
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
Syntax of granting privileges on the table of the database:
Below the syntax for grant privileges to the users to access the database Objects.
GRANT privileges ON object TO user;
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;
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:
The REVOKE command is used to withdraw the already granted permission to the database users.
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.
Syntax of revoke privileges on the table of the database:
Below the syntax for revoke privileges from the users.
REVOKE privileges ON object FROM user;
If you want to revoke SELECT, UPDATE, and DELETE privileges on a table name customer from a database user name Akash. The syntax is as follows:

If you want to revoke all privileges from the database users Akash on the same table (customer). The syntax looks like this:
