What are the types of SQL Queries ?

We have four types of SQL Queries:

DDL (Data Definition Language): the creation of objects
DML (Data Manipulation Language): manipulation of data
DCL (Data Control Language): assignment and removal of permissions
TCL (Transaction Control Language): saving and restoring changes to a database

Let’s look at the different commands under DDL:

Command	Description
CREATE	Create objects in the database
ALTER	Alters the structure of the database object
DROP	Delete objects from the database
TRUNCATE	Remove all records from a table permanently
COMMENT	Add comments to the data dictionary
RENAME	Rename an object
