XML Info Information: Feedback Author an Article Published: Wednesday, April 19, 2006 TRY...CATCH in SQL Server 2005An Easier Approach to Rolling Back Transactions in the Face of an Error By http://www.4guysfromrolla.com/webtech/041906-1.shtml Scott Mitchell Introduction SQL Server 2005 offers a number of new features over its predecessor, including many features aimed at making working with databases more like writing .NET application 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 of this article, is SQL Server 2005's support for TRY...CATCH sql server 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 be handled, logged, and so on. See the Wikipedia Exception Handling entry for more information in sql server 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, imagine that we have a data-driven web application that maintains employee information. Let's assume that our database has Employees and EmployeePhoneNumbers tables, among others. These two tables share a one-to-many
