MS SQL Server Concepts and Programming Question:

A DML trigger is a trigger declared to handle a DML event, which occurs when an INSERT, UPDATE or DELETE statement is executed. If you want to create a DML trigger, you should use the "CREATE TRIGGER" statement in the following format:

CREATE TRIGGER trigger_name ON table_name
AFTER INSERT, UPDATE, DELETE
AS
statements
GO

The tutorial exercise below shows you a very simple DML trigger defined on the ggl_users table. It does nothing but printing a simple static message.

USE GlobalGuideLineDatabase;
GO

CREATE TRIGGER dml_message ON ggl_users
AFTER INSERT, UPDATE, DELETE
AS
PRINT 'Records are inserted, updated,'
+ ' or deleted in ggl_users';
GO
Command(s) completed successfully.

A simple DML trigger is defined on ggl_users now.
