SERVER - 2005 - Explanation of TRY…CATCH and ERROR Handling April 11, 2007Pinal DaveSQL, SQL Performance, SQL Server, SQL Tips and Tricks46 commentsSQL Server 2005 offers a more robust set of tools for handling errors http://blog.sqlauthority.com/2007/04/11/sql-server-2005-explanation-of-trycatch-and-error-handling/ than in previous versions of SQL Server. Deadlocks, which are virtually impossible http://www.4guysfromrolla.com/webtech/041906-1.shtml to handle at the database level in SQL Server 2000, can now be handled with ease. By taking advantage of these new features, you can focus more on IT business strategy development and less on what needs to happen when errors occur. In SQL Server 2005, @@ERROR variable is sql server no longer needed after every statement executed, as was the case in SQL Server 2000. SQL Server 2005 provides the TRY…CATCH construct, which is already present in many modern programming languages. TRY/CATCH helps to write logic separate the action and error handling code. The code meant for the action is enclosed in the TRY block and the code for error in sql server handling is enclosed in the CATCH block. In case the code within the TRY block fails, the control automatically jumps to the CATCH block, letting the transaction roll back and resume execution. In addition to this, the CATCH block captures and provides error information that shows you the ID, message text, state, severity and transaction state of an error.Functions to be used in CATCH block are :ERROR_NUMBER: returns the error number, and is the same value of @@ERROR.ERROR_SEVERITY: returns the severity level of the error that invoked the CATCH block.ERROR_STATE: returns the state number of the error.ERROR_LINE: returns the line number where the error occurred.ERROR_PROCEDURE: returns the name of the stored procedure or trigger for which the error occurred.ERROR_MESSAGE: returns the full message text of the error. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.You can use these functions anywhere inside a CATCH block, and they will return information regarding the error that has occurred. These functions will return the value null outside of the CATCH block. Syntax: BEGIN

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 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 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 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.
