"CREATE TRIGGER" - Creating a DML Trigger in SQL Server

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 fyi_users table. It does nothing but printing a simple static message.
USE FyiCenterData;
GO
CREATE TRIGGER dml_message ON fyi_users
AFTER INSERT, UPDATE, DELETE
AS
PRINT 'Records are inserted, updated,'
+ ' or deleted in fyi_users';
GO
Command(s) completed successfully.
A simple DML trigger is defined on fyi_users now.
