A group of Transact-SQL statements can be enclosed in a TRY block. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.

Join them; it only takes a minute: Sign up Ignoring errors in Trigger up vote 4 down vote favorite I have a stored procedure which is called inside a trigger on Insert/Update/Delete. The problem is that there https://msdn.microsoft.com/en-us/library/ms175976.aspx is a certain code block inside this SP which is not critical. Hence I want to ignore any erros arising from this code block. I inserted this code block inside a TRY CATCH block. But to my surprise I got the following error: The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction. Then I tried using SAVE & ROLLBACK TRANSACTION along with TRY CATCH, that too http://stackoverflow.com/questions/9971602/ignoring-errors-in-trigger failed with the following error: The current transaction cannot be committed and cannot be rolled back to a savepoint. Roll back the entire transaction. My server version is: Microsoft SQL Server 2008 (SP2) - 10.0.4279.0 (X64) Sample DDL: IF OBJECT_ID('TestTrigger') IS NOT NULL DROP TRIGGER TestTrigger GO IF OBJECT_ID('TestProcedure') IS NOT NULL DROP PROCEDURE TestProcedure GO IF OBJECT_ID('TestTable') IS NOT NULL DROP TABLE TestTable GO CREATE TABLE TestTable (Data VARCHAR(20)) GO CREATE PROC TestProcedure AS BEGIN SAVE TRANSACTION Fallback BEGIN TRY DECLARE @a INT = 1/0 END TRY BEGIN CATCH ROLLBACK TRANSACTION Fallback END CATCH END GO CREATE TRIGGER TestTrigger ON TestTable FOR INSERT, UPDATE, DELETE AS BEGIN EXEC TestProcedure END GO Code to replicate the error: BEGIN TRANSACTION INSERT INTO TestTable VALUES('data') IF @@ERROR > 0 ROLLBACK TRANSACTION ELSE COMMIT TRANSACTION GO sql-server transactions triggers try-catch share|improve this question asked Apr 2 '12 at 6:09 Adi 3816 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote accepted I'd suggest re-architecting this so that you don't poison the original transaction - maybe have the transaction send a service broker message (or just insert relevant data into some form of queue table), so that the "non-critical" part can take place in a completely independent transaction. E.g. your trigger becomes: CREATE TRIGGER TestTrigger ON TestTable FOR INSERT, UPDATE, DELETE AS BEGIN INSERT INTO QueueTable (Col1,Col2) SELECT COALESCE(i.Col1,d.Col1),C

Join them; it only takes a minute: Sign up Here's how sql server it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Why TRY CATCH does not suppress exception in trigger up vote 3 down vote favorite I have a trigger on a table (source) that data should be copied to the other one (target) in other database. I am trying to implement custom synchronization process for data: in sql server 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 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
