Problem Definition Triggers are strange objects that have their own rules! First rule says that triggers are part of the invoking transaction (the transaction that fired them). Yes, this is True and it means that at the beginning of the trigger, both values of @@trancount and xact_state() are "1". So, if we use COMMIT or ROLLBACK inside thetrigger, their values will change to "0" just after executing these statements. Second strange rule is that if the transaction ended in the trigger, the database raises an abortion error. An example for this rule is executing COMMIT or ROLLBACK within the trigger.

Thanks. sql sql-server-2005 share|improve this question asked Nov 6 '09 at 16:50 Jordan 6491529 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted No, you have http://stackoverflow.com/questions/1688866/raising-errors-in-after-triggers-sql-server-2005 to rollback transaction by calling ROLLBACK TRAN: CREATE TRIGGER trg_au_table ON dbo.table AFTER UPDATE AS BEGIN ROLLBACK TRAN END GO This example will prevent from updating any record. This: CREATE TRIGGER trg_au_table ON dbo.table AFTER UPDATE AS BEGIN RAISERROR('This is a test', 16, 1) END GO will only raise the error but the change will be made in the table. share|improve this answer answered Nov 6 '09 at 17:04 Lukasz Lysik 7,17813661 So, is there an implicit transaction? If I have not begun a transaction explicitly, will ROLLBACK TRAN cause any issues? Thanks! –Jordan Nov 6 '09 at 18:50 Yes, there is an implicit transaction. Update and trigger are closed in one transaction. Trigger is always in one transaction with DML or DDL statement. If you perform an UPDATE you have to wait until the statements in the trigger are finished. RAISERROR does not rollback transaction. –Lukasz Lysik Nov 6 '09 at 19:23 Noting that any rollback statement (without listing a savepoint) will rollback all existing open transactions.
