Join them; it only takes a minute: Sign up What is the best practice use of SQL Server T-SQL error handling? up vote 20 down vote favorite 12 We have a large application mainly written in SQL sql @@error 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 is set rollback (if necessary) is done info is written (INSERT) to log table return with a error number, unique @@error sql server 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-server sql-server-2005 tsql error-handling share|improve this question edited Sep 5 '13 at 8:33 SteveC 4,029125096 asked Apr 7 '09 at 14:02 KM. 67.3k22121162 add a comment| 5 Answers 5 active oldest votes up vote 24 down vote accepted You should r
This part is also available in a Spanish translation by Geovanny Hernandez. Introduction This article is the first in a series of three about error and transaction handling in SQL Server. The aim of this first article is to give you a jumpstart with error handling by showing you a basic pattern which is good for the main bulk of your code. This part is written with the innocent and inexperienced reader in mind, why I am intentionally silent on many details. The purpose here is to tell you how without dwelling much on why. If you take my words for your truth, you may prefer to only read this part and save the other two for a later point in your career. On the other hand, if you question my guidelines, you certainly need to read the other two parts, where I go into much deeper detail exploring the very confusing world of error and transaction handling in SQL Server. Parts Two and Three, as well as the three appendixes, are directed towards readers with a more general programming experience, although necessarily not with SQL Server. This first article is short; Parts Two and Three are considerably longer. Table of Contents Introduction Index of All Error-Handling Articles Why Error Handling? Essential Commands TRY-CATCH SET XACT_ABORT ON General Pattern for Error Handling Three Ways to Reraise the Error Using error_handler_sp Using ;THROW Using SqlEventLog Final Remarks End of Part One Revision History Index of All Error-Handling Articles Here follows a list of all articles in this series: Part One - Jumpstart Error Handling (this article). Part Two - Commands and Mechanisms. Part Three - Implementation. Appendix 1 - Linked Servers. (Extends Part Two.) Appendix 2 - CLR. (Extends both Parts Two and Three.) Appendix 3 - Service Broker. (Extends Part Three.) All the articles above are for SQL2005 and later. For those who still are on SQL2000, there are two older articles: Error Handling in SQL Server 2000 – a Background. Implementing Error Handling with Stored Procedures in SQL2000. Why Error Handling? Why do we have error handling in our code? There are many reasons. In a forms application we validate the user input and inform the users of their mistakes. These user mistakes
