How to use the grant command in a database?

In a database, the grant command is used to give users specific permissions to perform operations on objects within the database, such as tables, views, and stored procedures, including SELECT, INSERT, UPDATE, and DELETE operations.

The basic syntax of the grant command is as follows:

GRANT privileges ON object TO user;

Privileges refer to granted permissions such as SELECT, INSERT, UPDATE, DELETE, etc., with the option to use ALL PRIVILEGES to grant all permissions. Object represents the item to be authorized, which can be a table, view, stored procedure, etc. User represents the individual being granted access.

For example, to grant user “test” permission to perform SELECT operations on the table “students”, you can use the following statement:

GRANT SELECT ON students TO test;

It is important to note that the grant command usually requires sufficient privileges to execute, typically only the database administrator or users with enough permissions can execute the grant command. It is also important to carefully control authorizations for database security reasons and only grant necessary permissions to users.
