A group of Transact-SQL statements can be enclosed in a TRY block. If an error occurs in the TRY block, control is passed to another group of statements that is enclosed in a CATCH block.

error handling of SQL Server has always been somewhat mysterious. Now sql @@trancount at last, the THROW statement has been included in SQL Server 2012 that, combined with the
Error Handling In Sql Server 2008
TRY ... CATCH block, makes error handling far easier. Robert Sheldon explains all. 195 14 Robert Sheldon Since the release of SQL Server 2005, you've been able https://msdn.microsoft.com/en-us/library/ms175976.aspx to handle errors in your 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, https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ the CATCH portion-you've been able to include a 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 ha
This part is also available in a Spanish translation by Geovanny Hernandez. Introduction This article is the first in a series of three about error and transaction handling http://www.sommarskog.se/error_handling/Part1.html in SQL Server. The aim of this first article is to give you a jumpstart with error handling by showing you a basic pattern which is good for the main bulk of your code. This part is written with the innocent and inexperienced reader in mind, why I am intentionally silent on many details. The purpose here is to tell you how without dwelling much sql server on why. If you take my words for your truth, you may prefer to only read this part and save the other two for a later point in your career. On the other hand, if you question my guidelines, you certainly need to read the other two parts, where I go into much deeper detail exploring the very confusing world of error and transaction handling in in sql server SQL Server. Parts Two and Three, as well as the three appendixes, are directed towards readers with a more general programming experience, although necessarily not with SQL Server. This first article is short; Parts Two and Three are considerably longer. Table of Contents Introduction Index of All Error-Handling Articles Why Error Handling?
