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 http://www.codeproject.com/Articles/38650/Overview-of-Error-Handling-in-SQL-Server 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 http://www.4guysfromrolla.com/webtech/041906-1.shtml 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 relationship; that is, each Employees
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 than in previous versions of SQL http://blog.sqlauthority.com/2007/04/11/sql-server-2005-explanation-of-trycatch-and-error-handling/ Server. Deadlocks, which are virtually impossible to handle at the database level in http://sqlmag.com/t-sql/error-handling-sql-server-2005 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 no longer needed after every statement executed, as was the case sql server 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 handling is enclosed in the CATCH block. In case the code within the TRY block fails, the in sql server 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 TRY
{ sql_statement |
statement_block }
END TRY
BEGIN CATCH

Error-handling code isn't structured and many errors aren't trappable. SQL Server 2005 introduces new T-SQL error-handling capabilities that let you handle errors elegantly and efficiently. Let's review the main problems you face today when you need to write error-handling code, then I'll introduce SQL Server 2005's new error-handling construct and describe how it addresses the problems you face in earlier versions. Error Handling Before SQL Server 2005 When you write error-handling code in T-SQL now, you face three main problems. First, there's no structured construct for identifying errors and handling them. All you have is the @@error() function, which returns an integer representing the way the previous statement finished. A zero means the statement was successful; any other value means an error occurred. You have to copy the value that @@error() returns for the statement into your own variable immediately after the statement that results in errors. Issuing another statement after the suspect one will cause the previous error ID that @@error() returns to be overridden and lost. So you usually end up with error-handling code after every suspect statement or with a nonstructured GOTO
