SQL uses certain commands like Create, Drop, Insert, etc. to carry out the required tasks. These SQL commands are mainly categorized into four categories as: DDL Data Definition Language; DQl Data Query Language; DML Data Manipulation Language; DCL Data Control Language Here are some commands that come under DCL: a.
