SQL Server 2000 Error Handling in T-SQL: From Casual to Religious Dejan Sunderic Most of us would agree that experienced programmers tend to be more adept at (and perhaps even more "religious" about) error handling than rookies. VB and C/C++ programmers are so spoiled by the error-handling tools in their IDEs that they sometimes forget good

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 http://www.sommarskog.se/error_handling/Part1.html 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 error handling 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 error handling sql 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 are anticipated errors. But we also need to handle unanticipated errors. That is, errors that occur because we overlooked something when we wrote our code. A simple strategy is to abort execution or at least revert to a point where we know that we have full control. It cannot be enough stressed that it is entirely impermissible to ignore an unanticipated error. This is a sin that can have grave consequences: it could cause the application to present inc
