This documentation is archived and is not being maintained. Using TRY...CATCH in Transact-SQL Errors in Transact-SQL code can be processed by using a TRY…CATCH construct similar to the exception-handling features of the Microsoft Visual C++ and Microsoft Visual C# languages. A TRY…CATCH construct consists of two parts: a TRY block and a CATCH block. When an error condition is detected in a Transact-SQL statement that is inside a TRY block, control is passed to a CATCH block where the error can be processed. After
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

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 https://technet.microsoft.com/en-us/library/ms179296(v=sql.105).aspx 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,

How, at the end of the SP can I trap the errors and do a sql server stored IF Error Count>0 THEN ROLLBACK DECLARE @errCount int=0 DECLARE @DataSetCount int=0 DECLARE @countCurrent int=0 DECLARE @countHistorical int=0 IF (isnumeric(@DataSetID)=(0) OR @DataSetID=(0)) BEGIN RAISERROR('The DataSet specfied does not appear to be valid', 5, 1) END ELSE IF (@Destination='C' OR @Destination='H') BEGIN if Exists (SELECT NULL from tblOpportunityDataSets where DataSetID=@DataSetID) BEGIN SET @countCurrent=(SELECT COUNT(1) from tblOptyRecordsCurrent where DataSetID=@DataSetID) SET @countHistorical=(SELECT COUNT(1) from tblOptyRecordsHistorical where DataSetID=@DataSetID) IF @destination='C' BEGIN if @countCurrent>0 BEGIN RAISERROR('There are already existing records in the Current Tables for the specified DataSet', 5, 1) END ELSE if @countHistorical=0 BEGIN RAISERROR('There do not appear to be any records in the Historical Tables to transfer for the specified Dataset', 5, 1) END ELSE BEGIN -- ENTER TRANSFER CODE INSERT INTO tblRecordsHistorical ( X, Y, Z ) SELECT X, Y, Z FROM tblA WHERE x=y -- Check that record count in both tables match SET @countCurrent=(SELECT COUNT(1) from tblOptyRecordsCurrent where DataSetID=@DataSetID) SET @countHistorical=(SELECT COUNT(1) from tblOptyRecordsHistorical where DataSetID=@DataSetID) IF (@countCurrent<>@countHistorical) BEGIN RAISERROR('There was an error whilst copying the records into the Historical Tables, Source and Destination Record Count do not match', 5, 1) END ELSE BEGIN END END END ELSE IF @Destination='H' BEGIN if @countHistorical>0 B

Advertisement: Handling SQL Server Errors in Nested Procedures By Talmage, Ron Tweet Talmage, Ron Ron Talmage is a mentor and co-founder of Solid Quality Mentors. He is a SQL Server MVP, a PASS Regional Mentor, and current president of the Pacific Northwest SQL Server Users Group. He has been writing white papers and articles on SQL Server since way back when. This article was published in: This article was filed under: VFP and SQL Server SQL Server Data Advertisement: Basic error handling in SQL Server's programming language, Transact-SQL, is straightforward.But when you nest calls to stored procedures, and the procedures have SQL transactions, error handling becomes much more complex. In this article I'll show you some tried-and-true models for how to handle errors in nested stored procedures with transactions.Over the past year I've worked on two projects that needed a strategy for handling errors in stored procedures where the procedures used transactions. My task was to come up with a way to gracefully exit from the stored procedures when non-fatal errors were detected so I could roll back the transaction. I'll present the result of that work in the two models you'll learn about in this article.So how do you handle errors in your code when an error occurs? Unless it encounters a broken connection, SQL Server will return an error to the client application. When you work directly with your own client or middle-tier code, you have much more control over how you handle errors. So you could just issue all your queries to SQL Server discretely from your client code and let SQL Server errors throw you into your error-cat
