Q:

What are the different types of SQL statements ?

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.
