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. Next code shows these rules: -- create test table IF OBJECT_ID('dbo.Test', 'U') IS NOT NULL DROP TABLE dbo.Test ; GO CREATE TABLE dbo.Test ( Id INT IDENTITY PRIMARY KEY, NAME NVARCHAR(128) ) ; GO -- create test trigger CREATE TRIGGER dbo.TriggerForTest ON dbo.Test AFTER INSE

Sql Server Instead Of Update Trigger
you, helping each other. Join them; it only takes a minute: Sign up Raising errors in After Triggers Sql Server 2005 up vote 0 down vote favorite If I raise an error in an AFTER UPDATE trigger in http://social.technet.microsoft.com/wiki/contents/articles/22177.error-handling-within-triggers-using-t-sql.aspx Sql Server 2005, will that cause the update which caused the trigger to be fired to roll back, even if the statement was not executed within a transaction? 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 http://stackoverflow.com/questions/1688866/raising-errors-in-after-triggers-sql-server-2005 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.

The CATCH block gives you a single place to code error handling logic in the event that a problem occurs anywhere inside the TRY block above it. Before TRY/CATCH, it was necessary to always check for error conditions after every operation by testing the built-in system function @@ERROR. Not only did code become cluttered with the many @@ERROR tests, developers (being humans) would too often forget to test @@ERROR in every needed place, causing many unhandled exceptions to go unnoticed. In SQL Server 2005, TRY/CATCH represented a vast improvement over constantly testing @@ERROR, but RAISERROR has (until SQL Server 2012) remained as the only mechanism for generating your own errors. In SQL Server 2012, the new THROW statement (again, borrowed from throw in the .NET model) is the recommended alternative way to raise exceptions in your T-SQL code (although RAISERROR does retain several capabilities that THROW lacks, as I’ll explain shortly). Re-Throwing Exceptions The new THROW statement can be used in two ways. First, and as I just stated, it can serve as an alternative to RAISERROR, allowing your code to generate errors when it detects an unresolvable condition in processing. Used for this purpo
