- SQL Commands | DDL, DQL, DML, DCL and TCL Commands
SQL commands are crucial for managing databases effectively These commands are divided into categories such as Data Definition Language (DDL), Data Manipulation Language (DML), Data Control Language (DCL), Data Query Language (DQL), and Transaction Control Language (TCL) In this article, we will explain the different types of SQL commands, including DDL, DML, DCL, DQL, and TCL
