Explain what the GRANT statement is and how it pertains to the security of the system. What kinds of privileges are possible to be granted? What is the procedure for revoking them?

GRANT statement's syntax is as follows:

EXTEND the grant option to include parameters (1) and (2), and (3) in the grant.

This is the privilege of access privileges assigned to the user, parameter(1).

The object name is the second parameter. It might also refer to a table or an item in the database.

Parameter(3) specifies which user would get the additional rights.
All of the above are examples of privileges that may be granted to an individual.

GRANT INSERT, SELECT, and DELETE ON USERS TO '*'@'localhost';
