| DDL: Data Definition Language (DDL) statements are used to define the database structure or schema. examples: CREATE - to create objects in the database. ALTER - alters the structure of the database. DML: Data Manipulation Language (DML) statements are used for managing data within schema objects. Some examples: SELECT - retrieve data from the a database. INSERT - insert data into a table. UPDATE - updates existing data within a table. DCL: Data Control Language (DCL) statements TCL: Transaction Control (TCL) statements are used to manage the changes made by DML statements. It allows statements to be grouped together into logical transactions. |
