TSQL: Try-Catch Transaction in Trigger

Question

I am trying to put a try-catch statement inside a trigger using Microsoft Server 2005.

BEGIN TRANSACTION
BEGIN TRY
    --Some More SQL
    COMMIT TRANSACTION         


        

Answer 1

To avoid losing the transactional data prior to the trigger action, you'll want to call COMMIT TRAN. Do this before the TRY/CATCH block and you will get your desired results.

Example:

COMMIT TRAN
BEGIN TRY
    -- possible error occurs here...
END TRY
BEGIN CATCH
    PRINT 'Error on line ' + CAST(ERROR_LINE() AS VARCHAR(10))
    PRINT ERROR_MESSAGE()
END CATCH

It will throw the following error still - not sure how to avoid:

The transaction ended in the trigger. The batch has been aborted.

But both the original transaction and the trigger transaction should commit successfully.

UPDATE: To avoid the exception last error, call BEGIN TRAN within the TRY statement. Note, Microsoft recommends to NOT call COMMIT TRAN within a trigger, but if unavoidable, this should work for you.

Example:

COMMIT TRAN
BEGIN TRY
    BEGIN TRAN
