Sql Server Stored Procedure Error Handling Best Practices
<> 0) BEGIN ROLLBACK TRAN RETURN END COMMIT TRAN I have another in a stored procedure that simply is: BEGIN TRANSACTION --Some deltes and inserts COMMIT TRANSACTION I have tested and found that my procedure always rolls everything back during an error (tested for example changing a column data type etc.) without explicitly coding a rollback. Also I have read that using @@error condition is outdated for SQL Server 2005 and above. What would you say is the correct way sql server try catch transaction of doing a transaction for SQL Server 2008 R2 and above?

I would do a stored procedure based on this template for SQL Server 2005 and newer: BEGIN TRANSACTION BEGIN TRY -- put your T-SQL commands here -- if successful - COMMIT the work COMMIT TRANSACTION END TRY BEGIN CATCH -- handle the error case (here by displaying the error) 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 -- in case of an error, ROLLBACK the transaction ROLLBACK TRANSACTION -- if you want to log this error info into an error table - do it here -- *AFTER* the ROLLBACK END CATCH share|improve this answer edited Jan 22 '14 at 18:09 answered Jan 22 '14 at 18:03 marc_s 454k938701033 3 +1 just one comment, you should perform the log after the rollback, else you'll rollback the write to the log table too. :-) –Aaron Bertrand Jan 22 '14 at 18:07 @AaronBertrand: good point! :-) I've never felt the need to log the error to a table - but you're absolutely right –marc_s Jan 22 '14 at 18:08 1 "handle

This part is also available in a Spanish translation by Geovanny Hernandez. Introduction This article is the first in a series of three about error and transaction handling http://www.sommarskog.se/error_handling/Part1.html in SQL Server. 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 http://www.codeproject.com/Articles/4451/SQL-Server-Transactions-and-Error-Handling your code. This part is written with the innocent and inexperienced reader in mind, why I am intentionally silent on many details. The purpose here is to tell you how without dwelling much sql server on why. If you take my words for your truth, you may prefer to only read this part and save the other two for a later point in your career. 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 error and transaction handling in in sql server SQL Server. Parts Two and Three, as well as the three appendixes, are directed towards readers with a more general programming experience, although necessarily not with SQL Server.

These files are located in the \Data directory. Re-creating the Pubs database requires the Instpubs.sql script to be executed. Run the script from the command line
