Can You Roll Back the DDL Statement in a Trigger?
Can you roll back the DDL statement in a trigger? The answer is yes.
Since the DDL statement that fires the trigger and the statements defined inside
the trigger are all executed as a single statement batch, you can add a ROLLBACK
statement in the trigger to rollback the entire batch.
USE FyiCenterData;
GO
CREATE TRIGGER drop_rollback ON DATABASE
AFTER DROP_TABLE
AS
PRINT 'Drop table is not allowed!';
ROLLBACK;
GO
DROP TABLE fyi_users;
GO
Drop table is not allowed!
Msg 3609, Level 16, State 2, Line 2
The transaction ended in the trigger. The batch has been aborted.
This trigger is powerful. It will stop you from dropping any tables in FyiCenterData database.
