I created a stored procedure which sql server stored procedure error handling best practices works most of the time, but I found an instance of where it doesn't do what I want. Currently, the code does something like this if @@error <> 0 begin select @message_error = "There was a database error adding product "+ @product + " to product line end Where @message_error is an output variable. So, I can select @@error and get a number, but all I really want is the SQL error. Something like Hey, I couldn't

do this because there is a fk constraint on this column or whatever. I found this article on msdn http://msdn.microsoft.com/en-us/library/ms178592(v=sql.90).aspx But it only goes over throwing custom exceptions with RAISERROR, I don't want to create my own error message or exception, I just want to know why stuff isn't working. I can execute the stored procedure through Management Studio and see the exact SQL error, but this is tedious trying to match data from the site and manually inserting it that way.

method of interacting with a database. When an error is encountered within a stored procedure, the best you can do (assuming it’s a non-fatal error) is halt the sequential processing of the code and either http://stackoverflow.com/questions/13647437/how-to-get-sql-error-in-stored-procedure branch to another code segment in the procedure or return processing to the calling application. Notice that the previous sentence is specific to non-fatal errors. There are two type of errors in SQL Server: fatal and non-fatal. Fatal errors cause a procedure to abort processing and terminate the connection with the client application. Non-fatal errors do not abort processing a procedure or affect the connection with the client application. When http://www.sqlteam.com/article/handling-errors-in-stored-procedures a non-fatal error occurs within a procedure, processing continues on the line of code that follows the one that caused the error. The following example demonstrates how a fatal error affects a procedure. USE tempdb go CREATE PROCEDURE ps_FatalError_SELECT AS SELECT * FROM NonExistentTable PRINT 'Fatal Error' go EXEC ps_FatalError _SELECT --Results-- Server:Msg 208,Level 16,State 1,Procedure ps_FatalError_SELECT,Line 3 Invalid object name 'NonExistentTable'. The SELECT in the procedure references a table that does not exist, which produces a fatal error. The procedure aborts processing immediately after the error and the PRINT statement is not executed. To demonstrate how a non-fatal error is processed, I need to create the following table. USE tempdb go CREATE TABLE NonFatal ( Column1 int IDENTITY, Column2 int NOT NULL ) This example uses a procedure to INSERT a row into NonFatal, but does not include a value for Column2 (defined as NOT NULL). USE tempdb go CREATE PROCEDURE ps_NonFatal_INSERT @Column2 int =NULL AS INSERT NonFatal VALUES (@Column2) PRINT 'NonFatal' go EXEC ps_NonFatal_INSERT --Results-- Server:Msg 515,Level 16,State 2,Procedure ps_NonFatal_INSERT,Line 4 Cannot insert the value NULL into column 'Column2',table 'tempdb.dbo.NonFatal'; column does not_allow nulls.INSERT fails. The statement has been terminated. NonFatal The last line of the results (shown in blue) demonstrates that the error did not affect th
how you should implement error handling when you write stored procedures, including when you call them from ADO. The other article, Error Handling in SQL Server - a Background, gives a deeper description of the http://www.sommarskog.se/error-handling-II.html idiosyncrasies with error handling in SQL Server and ADO. That article is in some sense http://forums.asp.net/t/1739122.aspx?How+can+I+return+a+text+message+error+from+a+stored+procedure+ part 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 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 stored procedure 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 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.

Command Timeouts Why is My Error Not Raised? Getting the Return Value from a Stored Procedure Acknowledgements and Feedback Revision History Introduction Error handling in stored procedures is a very tedious task, because T-SQL offers no exception mechanism, or any On Error Goto. All you have is the global variable @@error which you need to check after each statement for a non-zero value to be perfectly safe. If you call a stored procedure, you also need to check the return value from the procedure. In fact, this is so extremely tedious, so you will find that you will have to make compromises and in some situations assume that nothing can go wrong. Still, you cannot just ignore checking for errors, because ignoring an error could cause your updates to be incomplete, and compromise the integrity of your data. Or it can cause a transaction to run for much longer time than intended, leading to bloc
