There is really only one drawback: in some situations SQL Server raises two error messages, but the error_xxx() functions return only information about one of them, why one of the error Abhijit Jana | Codeproject MVP Web Site : abhijitjana.net Don't forget to click "Good Answer" on the post(s) that helped you. Back to my home page. If there is no nested TRY…CATCH construct, the error is passed back to the caller.TRY…CATCH constructs catch unhandled errors from stored procedures or triggers executed by the code in the TRY http://postmapper.com/sql-server/error-0-in-sql-server-2008.html

Listing 9: The error message returned by the UpdateSales stored procedure As expected, the information we included in the CATCH block has been returned. Error severities from 11 to 16 are typically user or code errors.

TRY-CATCH The main vehicle for error handling is TRY-CATCH, very reminiscent of similar constructs in other languages. Sql Server Error Code SELECT @ErrorVar = @@ERROR ,@RowCountVar = @@ROWCOUNT; -- Check for errors. In a Transaction, we can have multiple operations. PRINT N'Error = ' + CAST(@@ERROR AS NVARCHAR(8)); GO The following example returns the expected results.

Essential Commands We will start by looking at the most important commands that are needed for error handling. CREATE PROCEDURE usp_GetErrorInfo AS SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_LINE () AS ErrorLine ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_MESSAGE() AS ErrorMessage; GO -- SET XACT_ABORT ON will cause The header of the messages say that the error occurred in error_handler_sp, but the texts of the error messages give the original location, both procedure name and line number. Sql Error 803 The procedure name and line number are accurate and there is no other procedure name to confuse us.
But we also need to handle unanticipated errors. If no error message was sent when the transaction entered an uncommittable state, when the batch finishes, an error message will be sent to the client application. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.

A group of Transact-SQL statements can be enclosed in a TRY block. When you call a stored procedure on a linked server that raises an error, this error may bypass the error handler in the procedure on the local server and go to
