Join them; it only takes a minute: Sign up MSSQL: What happens when an error occurs during trigger execution? up vote 2 down vote favorite Regarding Update and Insert triggers for MS SQL Server, is there a way to make them atomic? In other words, if an error occurs during the trigger, is it possible to automatically raiserror in trigger sql server 2008 roll back the original insert or update? sql-server transactions triggers atomic share|improve this question asked Mar 27 '09 at 19:32 recursive 49k1694184 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted After triggers are automatically part of the insert/update/delete atomic DML statement on a table. You simply issue ROLLBACK TRAN in the trigger to rollback all work in the trigger and the original I/U/D statement. The outermost tran is also rolled back if there is one. Important Rollback in a trigger for SQL 2000 and earlier aborts the batch. No code after the offending I/U/D will run. See Erland great article and another For SQL 2005 with TRY/CATCH, execution will go to the CATCH block and your batch (aka stored proc etc) will exit normally. See Rollbacks and Commits in Stored Procedures and Triggers. The trigger and TRY/CATCH interation is here share|improve this answer answered Mar 27 '09 at 20:05 gbn 268k40379482 +1 for linking to Erland's articles. –Mark Brackett Mar 27 '09 a

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 to rollback transaction by calling ROLLBACK TRAN: CREATE TRIGGER trg_au_table ON dbo.table AFTER UPDATE AS BEGIN ROLLBACK http://stackoverflow.com/questions/1688866/raising-errors-in-after-triggers-sql-server-2005 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.

I am trying to implement custom synchronization process for data: I want that target database (table) will be up to date to source database (table). I have 3 hundred tables to synchronize. Some of then have different physical data structure. I cannot use sql server trigger standard approaches of Sql Server (replication, DTS...) because of different data schema and other restrictions (time to implement, environment issues...). My goal is: this trigger should NOT impact on INSERT, DELETE, UPDATE of records in a source table. I tried so solution: CREATE TRIGGER dbo.MyTrigger ... AFTER INSERT .... BEGIN TRY --RAISERROR('Test error', 16, 2) END TRY BEGIN CATCH -- nothing END CATCH I have inserted RAISEERROR to simulate error. I hoped, try/catch suppressed that error and record was been inserted (deleted, or updated) successfully. Don't. It does not work. I got error: An error was raised during trigger execution. The batch has been aborted and the user transaction, if any, has been rolled back. Is it possible to realize my solution in this way. How can I catch and hold (suppress) any error in my trigger? What sense to use try/catch in trigger if it does not work? sql-server-2008 trigger error-handling share|improve this question edited Dec 2 '11 at 15:37 asked Dec 2 '11 at 15:30 garik 3,56683150 add a comment| 1 Answer 1 active oldest votes up vote 5 down vote accepted The transaction is doomed with pretty much any exception and must be rolled back. From "Using TRY...CATCH in Transact-SQL" on MSDN Inside a TRY…CATCH construct, transactions can enter a state in which the transaction remains open but cannot be committed. The transaction cannot perform any action that would gener
