⟩ How To Test a DML Trigger in MS SQL Server?
To test a DML trigger defined on a table, you just need to execute several INSERT, UPDATE and DELETE statements on that table as shown in this tutorial example:
USE GlobalGuideLineDatabase;
GO
INSERT INTO ggl_users (name) VALUES ('GGL Admin');
GO
Records are inserted, updated, or deleted in ggl_users
(1 row(s) affected)
UPDATE ggl_users SET email='root@ggl'
WHERE name = 'GGL Admin';
GO
Records are inserted, updated, or deleted in ggl_users
(1 row(s) affected)
DELETE FROM ggl_users WHERE name = 'GGL Admin';
GO
Records are inserted, updated, or deleted in ggl_users
(1 row(s) affected)
The trigger, dml_message, is working as expected.
