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
Errors in SQL Server 2012 03 January 2013Handling Errors in SQL Server 2012The error handling of SQL Server has always been somewhat mysterious. Now sql server error handling nested stored procedures 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 error handling sql server 2000 Sheldon Since the 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 https://technet.microsoft.com/en-us/library/ms179296(v=sql.105).aspx 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 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 https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ 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 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
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 in SQL Server. The aim of this first article is to give http://www.sommarskog.se/error_handling/Part1.html 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 https://www.mssqltips.com/sqlservertutorial/164/using-try-catch-in-sql-server-stored-procedures/ many details. The purpose here is to tell you how without dwelling much 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 error handling 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 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 error handling in considerably longer. Table of Contents Introduction Index of All Error-Handling Articles Why Error Handling? Essential Commands TRY-CATCH SET XACT_ABORT ON General Pattern for Error Handling Three Ways to Reraise the Error Using error_handler_sp Using ;THROW Using SqlEventLog Final Remarks End of Part One Revision History Index of All Error-Handling Articles Here follows a list of all articles in this series: Part One - Jumpstart Error Handling (this article). Part Two - Commands and Mechanisms. Part Three - Implementation. Appendix 1 - Linked Servers. (Extends Part Two.) Appendix 2 - CLR. (Extends both Parts Two and Three.) Appendix 3 - Service Broker. (Extends Part Three.) All the articles above are for SQL2005 and later. For those who still are on SQL2000, there are two older articles: Error Handling in SQL Server 2000 – a Background. Implementing Error Handling with Stored Procedures in SQL2000. Why Error Handling? Why do we have error handling in our code? There are many reasons. In a forms application we validate the user input and inform the users of their mistakes. These user mistakes are anticipated errors. But we also need to handle unanticipated errors. That is, errors that occur because we overlooked something when we wrote our code. A simple strategy is to abort execution or at least revert to a point where we know that we have full control. It cannot be enough stressed that it is entirely i

Doing error handling in SQL Server has not always been the easiest thing, so this option definitely makes it much easier to code for and handle errors. Explanation If you are not familiar with the Try...Catch paradigm it is basically two blocks of code with your stored procedures that lets you execute some code, this is the Try section and if there are errors they are handled in the Catch section. Let's take a look at an example of how this can be done. As you can see we are using a basic SELECT statement that is contained within the TRY section, but for some reason if this fails it will run the code in the CATCH section and return the error information. CREATE PROCEDURE dbo.uspTryCatchTest AS BEGIN TRY SELECT 1/0 END TRY BEGIN CATCH SELECT ERROR_NUMBER() AS ErrorNumber ,ERROR_SEVERITY() AS ErrorSeverity ,ERROR_STATE() AS ErrorState ,ERROR_PROCEDURE() AS ErrorProcedure ,ERROR_LINE() AS ErrorLine ,ERROR_MESSAGE() AS ErrorMessage; END CATCH << Previous Next >> More SQL Server Solutions Post a comment or let the author know this tip helped.
