code. For example, in SQL Server 2005, stored procedures, triggers, UDFs, and so on can be written using any .NET Framework programming language (such as Visual Basic or C#). Another feature, and the focus https://msdn.microsoft.com/en-us/library/ms175976.aspx of this article, is SQL Server 2005's support for TRY...CATCH blocks. TRY...CATCH blocks are the standard approach to exception handling in modern programming languages, and involve: A TRY Block - the TRY block contains the instructions that might cause an exception A CATCH Block - if an exception occurs from one of the statements in the TRY block, control is branched to the CATCH block, where the exception can http://www.4guysfromrolla.com/webtech/041906-1.shtml be handled, logged, and so on. See the Wikipedia Exception Handling entry for more information on the TRY...CATCH construct as well as exception handling concepts in general. Prior to SQL Server 2005, detecting errors resulting from T-SQL statements could only be handled by checking a global error variable, @@ERROR. Because the @@ERROR variable value is reset after each SQL statement, this antiquated approach leads to rather bloated stored procedures, as the variable must be checked after each statement with code to handle any problems. The TRY...CATCH block in SQL Server 2005 offers a much more readable syntax and one that developers are more familiar with. In this article we'll look at the new TRY...CATCH block and examine how it can be used to rollback a transaction in the face of an error. Read on to learn more! -continued- Checking @@ERROR - the Old Way of Handling Errors in T-SQL SQL Server provides an @@ERROR variable that indicates the status of the last completed SQL statement in a given batch. If a SQL statement is completed successfully, @@ERROR is assigned 0. If, however, an error occurs, @@ERROR is set to the number of the error message. To see how the @@ERROR variable can be used, imagin
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 http://www.sommarskog.se/error_handling/Part1.html 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 http://searchsqlserver.techtarget.com/tip/Tune-stored-procedures-with-exception-handling-in-SQL-Server-2005 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 sql server 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 error handling in 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?

Exception handling was widely thought to be one of the weakest aspects of T-SQL script writing. Fortunately, this has changed in SQL Server 2005, which supports structured error handling. This tip focuses first on the basics of the new TRY…CATCH constructs and then looks at some sample SQL Server 2000 and 2005 T-SQL that produces constraint violations using transactional code. Future tips will continue along this theme. TABLE OF CONTENTS Exception handling before SQL Server 2005 Introducing SQL Server 2005 TRY...CATCH Structured
