A group of Transact-SQL statements can be enclosed in a TRY block. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.

features over its predecessor, including many features aimed at making working with databases more like writing .NET application code. For example, in try catch in sql server stored procedure 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 https://msdn.microsoft.com/en-us/library/ms175976.aspx 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 be handled, logged, and so on. See http://www.4guysfromrolla.com/webtech/041906-1.shtml 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, imagine that we have a data-driven web application that maintains employee information. Let's assume that
how you should implement error handling when you write stored procedures, including when you call them from ADO. The other article, Error http://www.sommarskog.se/error-handling-II.html Handling in SQL Server - a Background, gives a deeper description of the idiosyncrasies with error handling in SQL Server and ADO. That article is in some sense part one in the series. However, you can read this article without reading the background article first, and if you are not a very experienced user of SQL Server, I recommend you to stored procedure start here. In places there are links to the background article, if you want more information about a certain issue. Note: this article is aimed at SQL2000 and earlier versions of SQL Server. SQL2005 offers significantly improved methods for error handling with TRY-CATCH. This article is not apt if you are using SQL 2005 or later. I don't have a error handling in complete article on error handling for SQL 2005, but I have an unfinished article with a section Jumpstart Error Handling that still can be useful.

Getting the Return Value from a Stored Procedure Acknowledgements and Feedback Revision History Introduction Error handling in stored procedures is a very tedious task, because T-SQL offers no exception mechanism, or any On Error Goto. All you have is the global variable @@error which you need to check after each statement for a non-zero value to be perfectly safe. If you call a stored procedure, you also need to c
