Join them; it only takes a minute: Sign up What is the best practice use of SQL Server T-SQL error handling? up vote sql server 20 down vote favorite 12 We have a large application mainly written in SQL Server 7.0, where all database calls are to stored procedures. We are now running SQL Server 2005, which offers more T-SQL features. After just about every SELECT, INSERT, UPDATE, and DELETE, the @@ROWCOUNT and @@ERROR get captured into local variables and evaluated for problems. If there is a problem the following is done: error message output parameter in sql server is set rollback (if necessary) is done info is written (INSERT) to log table return with a error number, unique to this procedure (positive if fatal, negative is warning) They all don't check the rows (only when it is known) and some differ with more or less log/debug info. Also, the rows logic is somethimes split from the error logic (on updates where a concurrency field is checked in the WHERE clause, rows=0 means someone else has updated the data). However, here is a fairly generic example: SELECT, INSERT, UPDATE, or DELETE SELECT @Error=@@ERROR, @Rows=@@ROWCOUNT IF @Rows!=1 OR @Error!=0 BEGIN SET @ErrorMsg='ERROR 20, ' + ISNULL(OBJECT_NAME(@@PROCID), 'unknown') + ' - unable to ???????? 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 20 END I am looking into replacing how we do this with the TRY-CATCH T-SQL. I've read about the TRY...CATCH (Transact-SQL) syntax, so don't just post some summary of that. I'm looking for any good ideas and how best to do or improve our error handling methods. It doesn't have to be Try-Catch, just any good or best practice use of T-SQL error handling. sql
Coded Row'IF(@@ERROR <> 0)Print 'Error Occured'ELSE IF(@@ROWCOUNT = 0)Print 'No Rows Affected'The error occurs because the reference to @@ERROR in the first "IF" statement counts as a SQL statement; resetting the value held in @@ROWCOUNT. As the second "IF" statement checking @@ROWCOUNT is only evaluated if the first "IF" statement (@@ERROR) it will always return true! Note: Reversing the order of the two IF statements would hide any potential errors, as @@ERROR would be reset upon checking @@ROWCOUNT.The safest way to evaluate this statement is to SELECT the contents of @@ERROR and @@ROWCOUNT into local variables within a single statement and then check the values of the local variables, in other words:DECLARE @ErrorCode INTDECLARE @RowsAffected INT SELECT 'Hard Coded Row'SELECT @ErrorCode = @@ERROR, @RowsAffected = @@ROWCOUNT IF(@ErrorCode <> 0)Print 'Error Occured'ELSE IF(@RowsAffected = 0)Print 'No Rows Affected'Problem solved!
