Error Handling In Sql Server 2012
APPLIES TO: SQL Server (starting with 2008)Azure SQL DatabaseAzure SQL Data Warehouse Parallel Data Warehouse Implements error 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. Transact-SQL Syntax ConventionsSyntax Copy -- Syntax for SQL Server, Azure SQL Database, Azure SQL Data Warehouse, Parallel Data Warehouse BEGIN TRY { sql_statement | statement_block } END TRY BEGIN CATCH [ { sql_statement | statement_block } ] END CATCH [ ; ] Argumentssql_statement Is any Transact-SQL statement.statement_block Any group of Transact-SQL statements in a batch or enclosed in a BEGIN…END block.RemarksA TRY…CATCH construct catches all execution errors that have a severity higher than 10 that do not close the database connection.A TRY block must be immediately followed by an associated CATCH block.

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 http://www.sommarskog.se/error_handling/Part1.html Server. The aim of this first article is to give you a jumpstart http://www.sommarskog.se/error-handling-II.html 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 error handling 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, error handling in 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 info
how you should implement error handling when you write stored procedures, including when you call them from ADO. The other article, Error Handling in SQL Server - a Background, gives a deeper description of the idiosyncrasies with error handling in SQL Server and ADO. That article is in some sense part 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 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 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. Table of Contents: Introduction The Presumptions A General Example Checking Calls to Stored Procedures The Philosophy of Error Handling General Requirements Why Do We Check for Errors? When Should You Check @@error? ROLLBACK or not to ROLLBACK - That's the Question SET XACT_ABORT ON revisited Error Handling with Cursors Error Handling with Triggers Error Handling with User-Defined Functions Error Handling with Dynamic SQL Error Handling in Client Code What to Do in Case of an Error? Command Timeouts Why is My Error Not Raised? 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 perf
