Error Handling In Sqlserver 2008
Contents |
BloeschMarch 10, 20099 0 0 0 Error handling in SQL Server 2008 needs careful implementation. The Microsoft “Oslo” Repository’s API has the further problem that error handling in sql server 2008 stored procedure we cannot mandate the error handling logic in our callers. Thus a sql stored procedure try catch stored procedure call could be in a transaction or not and in a try-catch block or not. error handling in sql server 2012 Below is the pattern we have chosen based on experimentation and best practice guidance from the SQL Server team and other SQL Server experts. A test script for all error handling in stored procedure sql server 2012 the interesting cases can be found at http://blogs.msdn.com/cfs-file.ashx/__key/communityserver-components-postattachments/00-09-46-95-77/Error-Handling.sql. For a good overview of SQL Server error handling see http://www.sommarskog.se/error-handling-I.html and http://www.sommarskog.se/error-handling-II.html. In our design, we had the following main issues and mitigations: · A transaction rollback will rollback to the outermost transaction but if there is an outer transaction we would like to only rollback the changes to

the module’s inner transaction. The solution is to use SQL Server save points if there is an outer transaction. · A sufficiently severe raiserror will terminate a module if there is an outer try-catch block but if there is none then execution will continue in the module. The solution is to always explicitly return after raising an error. · Some developers like to use stored procedure return values to encode error states. The solution is to return appropriate error codes. · SQL Server will raise warnings if the transaction depth entering and leaving a transaction do not match. The solution is to be careful. · Triggers have an implicit transaction. The solution is to use a simplified pattern for triggers where a transaction is never started. · Save points need unique names if modules can nest otherwise you can rollback to the wrong save point. The solution is to use a GUID to name the save points. Here is the pattern for stored procedures (eliding our special error reporting routines): ifparameter errorbegin raiserro

I'd like it to perform the clean up, but return the original error if this insert fails (primarily for logging as I want to see exactly why the insert failed). Basically like a throw; in C#. Is there a simple way to do this? BEGIN TRY Insert http://stackoverflow.com/questions/14203256/stored-procedure-error-handling-clean-up-but-return-original-error into table (col1) values ('1") END TRY BEGIN CATCH --do clean up here --then throw original error END TRY Is this feasible/good practice? In the application code that calls the proc, I'm handling the error from an application standpoint, but the clean up statements seem to better fit inside the proc. sql-server-2008 stored-procedures error-handling share|improve this question asked Jan 7 '13 at 20:08 Tim Coker 4,59111847 usually you do roll back and clean up in the catch block. I personally thought that was one of the best uses of catch block in stored procedures. You just need to be sure that any of your roll back/clean up is not going to create more errors and that whatever you are trying to clean up, is malleable after your error. –Pow-Ian Jan 7 '13 at 20:11 1 The short answer is to use RAISERROR because there is no THROW in SQL Server until version 2012. This article gives the long answer: simple-talk.com/sql/database-administration/… –Pondlife Jan 7 '13 at 20:16 1 In SQL Server 2012 you can use THROW(). In SQL Server 2008 you can't throw/re-raise. –Aaron Bertrand Jan 7 '13 at 20:16 1 Can you explain how the selected answer actually solved thi
