They must be reraised. The same rational applies to the ROLLBACK TRANSACTION on the Catch block. CREATE PROCEDURE usp_GetErrorInfo AS 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; GO BEGIN TRY -- Generate divide-by-zero error.

Listing 4 shows the SELECT statement I used to retrieve the data. 123 SELECT FullName, SalesLastYearFROM LastYearSalesWHERE SalesPersonID = 288 Listing 4: Retrieving date from the LastYearSales table Not surprisingly, the As for how to reraise the error, we will come to this later in this article. For production-grade code it's not really sufficient to rely on XACT_ABORT, but for quick and simple stuff it can do. Sql Server Return I use level 16 as a default for an error that is raised and the sequence will be terminated.
This serves two purposes: 1) We can directly see that this is a message reraised from a CATCH handler. 2) This makes it possible for error_handler_sp to filter out errors it True, if you look it up in Books Online, there is no leading semicolon. All I have to do is try to add a negative amount to the SalesLastYear column, an amount large enough to cause SQL Server to throw an error. check it out The aim of this first article is to give you a jumpstart with error handling by showing you a basic pattern which is good for the main bulk of your code.
This part is written with the innocent and inexperienced reader in mind, why I am intentionally silent on many details. Sql Stop Query The CATCH handler above performs three actions: Rolls back any open transaction. Copy -- Verify that the stored procedure does not already exist. The logical next step is to group some of the code into a generic error-handling procedure such as this: Begin transaction Update .
If we were to execute the SELECT statement again (the one in Listing 4), our results would look similar to those shown in Listing 7. If there were two error messages originally, both are reraised which makes it even better. Sql Server Exit Script He is now a technical consultant and the author of numerous books, articles, and training material related to Microsoft Windows, various relational database management systems, and business intelligence design and implementation. T-sql Exit Rolling back changes' ROLLBACK TRANSACTION END Apparently the compiler "understands" the @finished variable in the IF, even if there was an error and the execution was disabled.
PRINT N'The job candidate has been deleted.'; RETURN 0; END; GO C. check over here The statement returns error information to the calling application. On the other hand, if you question my guidelines, you certainly need to read the other two parts, where I go into much deeper detail exploring the very confusing world of EXEC insert_data 8, NULL EXEC outer_sp 8, 8 This results in: Msg 50000, Level 16, State 2, Procedure error_handler_sp, Line 20 *** [insert_data], Line 5. Try Catch In Sql Server Stored Procedure
Inexperienced T-SQL programmers, however, might not be familiar with transaction processing and thus not realize that, if errors occurred while processing the second UPDATE, SQL Server would still unconditionally commit the Given that ice is less dense than water, why doesn't it sit completely atop water (rather than slightly submerged)? Note that it requires both severity 20 (or higher) and "WITH LOG". –Rob Garrison Sep 17 '09 at 15:41 3 Note that with noexec method the rest of the script his comment is here In many cases you will have some lines code between BEGIN TRY and BEGIN TRANSACTION.

But first, let's retrieve a row from the LastYearSales table to see what the current value is for salesperson 288.
This leads me to believe that something when REALLY wrong and the transaction was already killed.

What you return does not really matter, as long as it's a non-zero value. (Zero is usually understood as success.) The last statement in the procedure is END CATCH. However, the value is set to 1 only if the execution was not disabled.

As these statements should appear in all your stored procedures, they should take up as little space as possible. Cannot insert duplicate key in object 'dbo.sometable'. In this case, there should be only one (if an error occurs), so I roll back that transaction.
