⟩ How To Create a DML Trigger using CREATE TRIGGER Statements?
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.
