Warehouse Parallel Data Warehouse Implements error handling for Transact-SQL that is similar to the exception handling in the Microsoft Visual C# and Microsoft Visual C++ languages. 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.

Handling in SQL Server - a Background, gives a deeper description error handling in sql server 2008 of the idiosyncrasies with error handling in SQL Server and ADO. That article is in some sense part raise error sql 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 https://msdn.microsoft.com/en-us/library/ms175976.aspx you to 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 http://www.sommarskog.se/error-handling-II.html have a 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.

Doing error handling in SQL Server has not always been the easiest thing, so this option definitely makes it much easier to code for and handle errors. Explanation If you are not familiar with the Try...Catch paradigm it is basically two blocks of code with your stored procedures that lets you execute some code, this is the Try section and if there are errors they are handled in the Catch section. Let's take a look at an example of how this can be done. As you can see we are using a basic SELECT statement that is contained within the TRY section, but for some reason if this fails it will run the code in the CATCH section and return the error information. CREATE PROCEDURE dbo.uspTryCatchTest AS BEGIN TRY SELECT 1/0 END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_LINE() AS ErrorLine ,ERROR_MESSAGE() AS ErrorMessage; END CATCH << Previous Next >> More SQL Server Solutions Post a comment or let the author know this tip helped.
