There are 5 types of SQL commands:

  • Data Definition Language (DDL): Commands that are used to create, alter, and drop database objects such as tables, views, and stored procedures.
  • Data Manipulation Language (DML): Commands that are used to insert, update, delete, and select data from tables.
  • Data Query Language (DQL): Commands that are used to retrieve data from tables.
  • Transaction Control Language (TCL): Commands that are used to manage transactions, such as starting, committing, and rolling back transactions.
  • Data Control Language (DCL): Commands that are used to manage user access to databases, such as granting and revoking permissions.

Here is a table summarizing the 5 types of SQL commands:
