Correct Answer: SQL statements are broadly classified into three They are 1 DDL – Data Definition Language DDL is used to define the structure that holds the data For example, Create, Alter, Drop and Truncate table 2 DML – Data Manipulation Language DML is used for manipulation of the data itself Typical operations are Insert, Delete, Update and retrieving the data from the table The Select statement is considered as a limited version of the DML, since it can't change the data in the database But it can perform operations on data retrieved from the DBMS, before the results are returned to the calling function 3 DCL – Data Control Language DCL is used to control the visibility of data like granting database access and set privileges to create tables, etc Example - Grant, Revoke access permission to the user to access data in the database
