SQL Server 2000 Error Handling in T-SQL: From Casual to Religious Dejan Sunderic Most of us would agree that experienced programmers tend to be more adept at (and perhaps even more "religious" about) error handling than rookies. VB and C/C++ programmers are so spoiled by the error-handling tools

Sql Server Stored Procedure Error Handling Best Practices
Handling in SQL Server - a Background, gives a deeper description oracle stored procedure error handling of the idiosyncrasies with error handling in SQL Server and ADO. That article is in some sense part sql trigger error handling 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 https://technet.microsoft.com/en-us/library/aa175920(v=sql.80).aspx 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 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 http://www.sommarskog.se/error-handling-II.html 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.

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,
Errors in SQL Server 2012 03 January 2013Handling Errors in SQL Server 2012The error handling of https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ SQL Server has always been somewhat mysterious. Now at last, the THROW statement has been included in SQL Server 2012 that, combined with the TRY ... CATCH block, makes error handling far easier. Robert Sheldon explains all. 194 14 Robert Sheldon Since the release of SQL Server 2005, you've been able to handle errors in your error handling T-SQL code by including a TRY…CATCH block that controls the flow of your script should an error occur, similar to how procedural languages have traditionally handled errors. The TRY…CATCH block makes it easy to return or audit error-related data, as well as take other actions. And within the block-specifically, the CATCH portion-you've been able to include a stored procedure error RAISERROR statement in order to re-throw error-related data to the calling application. However, with the release of SQL Server 2012, you now have a replacement for RAISERROR, the THROW statement, which makes it easier than ever to capture the error-related data. In this article, we'll look at the TRY…CATCH block used with both the RAISERROR and THROW statements. The examples are based on a table I created in the AdventureWorks2012 sample database, on a local instance of SQL Server 2012. Listing 1 shows the T-SQL script I used to create the LastYearSales table. 123456789101112131415161718 USE AdventureWorks2012;GOIF OBJECT_ID('LastYearSales', 'U') IS NOT NULLDROP TABLE LastYearSales;GOSELECTBusinessEntityID AS SalesPersonID,FirstName + ' ' + LastName AS FullName,SalesLastYearINTOLastYearSalesFROMSales.vSalesPersonWHERESalesLastYear > 0;GO Listing 1: Creating the LastYearSales table The script should be fairly straightforward. I use a SELECT…INTO statement to retrieve data from the Sales.vSalesPerson view and insert it into the newly created table. However, to demonstrate how to handle errors, we need to add one more element to our table: a check constraint that ensures
