Sql Try Catch Transaction
a lot of database structure adjustments but it's not really safe to just let it go through when something fails. to make things clear: using MS SQL 2005 it's NOT a stored procedure, just a script file (.sql) what I have is something in the following order BEGIN TRANSACTION ALTER Stuff GO CREATE New Stuff GO DROP Old Stuff GO IF @@ERROR != 0 BEGIN PRINT 'Errors Found ... Rolling back' ROLLBACK TRANSACTION RETURN END sql server stored procedure error handling best practices ELSE PRINT 'No Errors ... Committing changes' COMMIT TRANSACTION just to illustrate what I'm working with ... can't go into specifics now, the problem ... When I introduce an error (to test if things get rolled back), I get a statement that the ROLLBACK TRANSACTION could not find a corresponding BEGIN TRANSACTION. This leads me to believe that something when REALLY wrong and the transaction was already killed. what I also noticed is that the script didn't fully quit on error and thus DID try to execute every statement after the error occured. (I noticed this when new tables showed up when I wasn't expecting them because it should have rollbacked) sql-server sql-server-2005 tsql transactions share|improve this question edited Jan 3 '12 at 15:01 user212218 asked May 26 '10 at 8:05 Jan W. 76142028 add a comment| 5 Answers 5 active oldest votes up vote 6 down vote accepted When the error occurs, the transaction is rolled back automatically, and the current batch is aborted. Execution continues into the next batch, however. So all the stuff in the batches after the error gets executed. And then when you check for errors later, you try to rollback an already rolled back transaction. Also, to stop the entire script, not just the current batch, you should use: raiserror('Error description here', 20, -1) wi

I would do a stored procedure based on this template for SQL Server 2005 and newer: BEGIN TRANSACTION BEGIN TRY -- put your T-SQL commands here -- if successful - COMMIT the work COMMIT TRANSACTION END TRY BEGIN CATCH -- handle the error case (here by displaying the error) 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 -- in case of an error, ROLLBACK the transaction ROLLBACK TRANSACTION -- if you want to log this error info into an error table - do it here -- *AFTER* the ROLLBACK END CATCH share|improve this answer edited Jan 22 '14 at 18:09 answered Jan 22 '14 at 18:03 marc_s 453k938691032 3 +1 just one comment, you should perform the log after the rollback,

Periodicals Microsoft SQL Server Professional June 2000 June 2000 Error Handling in T-SQL: From Casual to Religious Error Handling in T-SQL: From Casual to Religious Error
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, 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. 195 14 Robert 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 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 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 >=
