Exception Handling In Sql Stored Procedure
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.

Catch Commenting Code Naming Conventions SET NOCOUNT ON DROP Procedure ALTER Procedure Get Free SQL Tips << Previous Next >> By: Greg Robidoux Overview A great new option that was added in SQL Server 2005 was the ability to use stored procedure the Try..Catch paradigm that exists in other development languages. 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 stored procedure error 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.

Join them; it only takes a minute: Sign up What is the best practice use of SQL Server T-SQL error handling? up vote 20 down vote favorite 12 We have a large application mainly written in SQL Server 7.0, where all database calls are to stored procedures. We are now running SQL Server 2005, which offers more T-SQL features. After just about every SELECT, INSERT, UPDATE, and DELETE, the @@ROWCOUNT and @@ERROR get captured into local variables and evaluated for problems. If there is a problem the following is done: error message output parameter is set rollback (if necessary) is done info is written (INSERT) to log table return with a error number, unique to this procedure (positive if fatal, negative is warning) They all don't check the rows (only when it is known) and some differ with more or less log/debug info. Also, the rows logic is somethimes split from the error logic (on updates where a concurrency field is checked in the WHERE clause, rows=0 means someone else has updated the data). However, here is a fairly generic example: SELECT, INSERT, UPDATE, or DELETE SELECT @Error=@@ERROR, @Rows=@@ROWCOUNT IF @Rows!=1 OR @Error!=0 BEGIN SET @ErrorMsg='ERROR 20, ' + ISNULL(OBJECT_NAME(@@PROCID), 'unknown') + ' - unable to ???????? the ????.' IF @@TRANCOUNT >0 BEGIN ROLLBACK END SET @LogInfo=ISNULL(@LogInfo,'')+'; '+ISNULL(@ErrorMsg,'')+ + ' @YYYYY=' +dbo.FormatString(@YYYYY) +', @XXXXX=' +dbo.FormatString(@XXXXX) +', Error=' +dbo.FormatString(@Error) +', Rows=' +dbo.FormatString(@Rows) INSERT INTO MyLogTable (...,Message) VALUES (....,@LogInfo) RETURN 20 END I am looking into replacing how we do this with the TRY-CATCH T-SQL. I've read about the TRY...CATCH (Transact-SQL) syntax, so don't just post some summary of that. I'm looking for any good ideas and how best to do or improve our error handling methods. It doesn't have to be Try-Catch, just any good or best
