advantage of these new features, you can focus more on IT business strategy development and less on what needs to happen when errors occur. In SQL Server 2005, @@ERROR variable http://www.codeproject.com/Articles/38650/Overview-of-Error-Handling-in-SQL-Server is no longer needed after every statement executed, as was the case in SQL Server 2000. SQL Server 2005 provides the TRY…CATCH construct, which is already present in many modern programming languages. TRY/CATCH helps to write logic separate the action and error handling code. The code meant for the action is enclosed in the TRY block and the code for http://blog.sqlauthority.com/2007/04/11/sql-server-2005-explanation-of-trycatch-and-error-handling/ error handling is enclosed in the CATCH block. In case the code within the TRY block fails, the control automatically jumps to the CATCH block, letting the transaction roll back and resume execution. In addition to this, the CATCH block captures and provides error information that shows you the ID, message text, state, severity and transaction state of an error.Functions to be used in CATCH block are :ERROR_NUMBER: returns the error number, and is the same value of @@ERROR.ERROR_SEVERITY: returns the severity level of the error that invoked the CATCH block.ERROR_STATE: returns the state number of the error.ERROR_LINE: returns the line number where the error occurred.ERROR_PROCEDURE: returns the name of the stored procedure or trigger for which the error occurred.ERROR_MESSAGE: returns the full message text of the error. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.You can use these functions anywhere inside a CATCH block, and they will return information regarding the error that has occurred. These functions will return the value null outside of the CATCH block. Synta
Errors in SQL Server 2012 03 January 2013Handling Errors in https://www.simple-talk.com/sql/database-administration/handling-errors-in-sql-server-2012/ SQL Server 2012The error handling of SQL Server has always been http://www.sommarskog.se/error_handling/Part1.html 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 sql server 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 procedural languages have traditionally handled errors. The TRY…CATCH block makes it easy to return or audit error-related data, as well in sql server 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 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.vSa
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 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 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 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? 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 impermissible to ignore an
