Thus a stored procedure call could be in a transaction or not and sql server stored procedure error handling best practices in a try-catch block or not. Below is the pattern we have chosen based on experimentation and best practice guidance from the SQL Server team and

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.

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 http://stackoverflow.com/questions/14203256/stored-procedure-error-handling-clean-up-but-return-original-error TRY Insert 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 answ
| Tags: Stored Procedures, SQL Server 2005, Transactions, SQL Server 2008 Features, Error Handling This article covers the basics of TRY CATCH error handling in T-SQL introduced in http://www.sqlteam.com/article/handling-sql-server-errors SQL Server 2005. It includes the usage of common functions to return information about the error and using the TRY CATCH block in stored procedures and transactions. SQL Server uses the following syntax http://www.codeproject.com/Articles/38650/Overview-of-Error-Handling-in-SQL-Server to capture errors in Transact-SQL statements: BEGIN TRY SELECT [First] = 1 SELECT [Second] = 1/0 SELECT [Third] = 3 END TRY BEGIN CATCH PRINT 'An error occurred' END CATCH This returns the following stored procedure output: First ----------- 1 (1 row(s) affected) Second ----------- (0 row(s) affected) An error occurred A key difference from SQL Server 2000 is that execution is halted when SQL Server encounters an error. At that point execution transfers to the CATCH block. This error isn't returned to the client application or calling program. The TRY CATCH block consumes the error. Error Functions Inside the CATCH block there are stored procedure sql a number of specialized functions to return information about the error. BEGIN TRY SELECT [Second] = 1/0 END TRY BEGIN CATCH SELECT [Error_Line] = ERROR_LINE(), [Error_Number] = ERROR_NUMBER(), [Error_Severity] = ERROR_SEVERITY(), [Error_State] = ERROR_STATE() SELECT [Error_Message] = ERROR_MESSAGE() END CATCH Second ----------- (0 row(s) affected) Error_Line Error_Number Error_Severity Error_State ----------- ------------ -------------- ----------- 2 8134 16 1 (1 row(s) affected) Error_Message --------------------------------------------------- Divide by zero error encountered. (1 row(s) affected) These are the functions you can use inside a CATCH block. These functions all return NULL if they are called from outside a CATCH block. ERROR_NUMBER. The number of the error that occurred. This is similar to @@ERROR except that it will return the same number for the duration of the CATCH block. ERROR_MESSAGE. The complete text of the error message including any substiture parameters such as object names. ERROR_LINE. This is the line number of the batch or stored procedure where the error occured. ERROR_SEVERITY. This is the severity of the error. The CATCH block only fires for errors with severity 11 or higher. Error severities from 11 to 16 are typically user or code errors. Severity levels from 17 to 25 are usually software or hardware errors where proces
