DML and DDL Triggers - T-SQL Step by Step Course - Lesson 32 | SQL courses

In this video, we will discuss DML triggers and DDL triggers.

Duration: 17:09 min

Summary: In this video, we will discuss DML triggers and DDL triggers. A DML trigger is an action programmed to execute when a data manipulation language (DML) event occurs in the database server. DML events include UPDATE, INSERT, or DELETE statements issued against a table or view. DML triggers are used to enforce business rules when data is modified and to extend the integrity checking logic of Microsoft SQL Server constraints, defaults, and rules.

DDL triggers execute in response to a variety of data definition language (DDL) events. These events primarily correspond to Transact-SQL CREATE, ALTER, and DROP statements, and certain system stored procedures that perform DDL-like operations.
