TRY...CATCH (Transact-SQL) Other Versions SQL Server 2012 THIS TOPIC APPLIES TO: SQL Server (starting with 2008)Azure SQL DatabaseAzure SQL Data Warehouse Parallel Data Warehouse Implements error error handling in sql script handling for Transact-SQL that is similar to the exception handling in the Microsoft Visual C# and Microsoft Visual C++ languages. 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.

Errors in SQL Server 2012 03 January 2013Handling Errors in SQL Server 2012The error handling of SQL Server has always been somewhat mysterious. Now at last, https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ 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 https://www.toadworld.com/platforms/sql-server/w/wiki/10197.error-handling-functions release of SQL Server 2005, you've been able 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 error handling 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 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 error handling in 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 the SalesLastYear value is never less than zero. Listing 2 shows the ALTERTABLE statement I used to add the constraint. 123 ALTER TABLE LastYearSalesADD CONSTRAINT ckSalesTotal CHECK (SalesLastYear >= 0);GO Listing 2: Adding a check constraint to the LastYearSales table The constraint makes it easy to generate an error when updating the table. All I have to do is try to ad
