In actually, I need only to roll back the transaction and specify the THROW statement, without any parameters. The same rational applies to the ROLLBACK TRANSACTION on the Catch block. More exactly, when an error occurs, SQL Server unwinds the stack until it finds a CATCH handler, and if there isn't any, SQL Server sends the error message to the client. The purpose here is to tell you how without dwelling much on why.
For example, the CATCH block of an outer TRY...CATCH construct could have a nested TRY...CATCH construct.

To use SqlEventLog, your CATCH hander would look like this: BEGIN CATCH IF @@trancount > 0 ROLLBACK TRANSACTION EXEC slog.catchhandler_sp @@procid RETURN 55555 END CATCH @@procid returns the object id of Sql Server Stored Procedure Error Handling Best Practices The content you requested has been removed. Explanation If you are not familiar with the Try...Catch paradigm it is basically two blocks of code with your stored procedures that lets you execute some code, this is the Try the ????.' IF @@TRANCOUNT >0 BEGIN ROLLBACK END SET @LogInfo=ISNULL(@LogInfo,'')+'; '+ISNULL(@ErrorMsg,'')+ + ' @YYYYY=' +dbo.FormatString(@YYYYY) +', @XXXXX=' +dbo.FormatString(@XXXXX) +', Error=' +dbo.FormatString(@Error) +', Rows=' +dbo.FormatString(@Rows) INSERT INTO MyLogTable (...,Message) VALUES (....,@LogInfo) RETURN
Always. For uspLogError to insert error information into the ErrorLog table, the following conditions must exist:uspLogError is executed within the scope of a CATCH block.If the current transaction is in an uncommittable Try Catch In Sql Server Stored Procedure This -- statement will generate a constraint violation error. Sql Try Catch Throw However, if the UPDATE statement fails and SQL Server generates an error, the transaction is terminated and the database engine jumps to the CATCH block.
In the CATCH block of a TRY…CATCH construct, the stored procedure is called and information about the error is returned. navigate here In those days, the best we could do was to look at return values. When you activate XACT_ABORT ON, almost all errors have the same effect: any open transaction is rolled back and execution is aborted. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.These functions return NULL if they are called outside the scope of the CATCH block. Sql Server Try Catch Transaction
That's basically all you need to do to create a stored procedure that contains a TRY…CATCH block.

Error Handling In Sql Server 2012 The row counts can also confuse poorly written clients that think they are real result sets.

Sign Up Please Wait... Add this code to the example above: CREATE PROCEDURE outer_sp AS BEGIN TRY EXEC inner_sp END TRY BEGIN CATCH PRINT 'The error message is: ' + error_message() END CATCH go EXEC I would highly recommend Dot Net Tricks!! The batch that contains the TRY…CATCH construct is executing at a higher level than the stored procedure; and the error, which occurs at a lower level, is caught.
The error causes execution to transfer to the associated CATCH block inside usp_GenerateError where the stored procedure usp_RethrowError is executed to raise the constraint violation error information using RAISERROR. IF (XACT_STATE()) = -1 BEGIN PRINT N'The transaction is in an uncommittable state.' + 'Rolling back transaction.' ROLLBACK TRANSACTION; END; -- Test whether the transaction is committable.
