When a connection is broken, SQL Server stops all currently running commands and rollbacks the transaction. –Quassnoi Nov 17 '09 at 16:04 1 So DyingCactus's solution looks like it fixes ERROR_STATE(): The error's state number. http://stackoverflow.com/questions/1749719/sql-server-transactions-roll-back-on-error

Note: Be sure to match BEGIN TRAN with either COMMIT or ROLLBACK. MS has a pretty decent template for this behavior at: http://msdn.microsoft.com/en-us/library/ms188378.aspx (Just replace RAISERROR with the new THROW command). The catch block is not limited to just rolling back the transaction, it can log to error tables (after the rollback, so that the logging is not rolled back), it can

Join them; it only takes a minute: Sign up SQL Server 2008 R2 Transaction is @@error necessary and is ROLLBACK TRANS necessary up vote 1 down vote favorite 1 My colleague The information is explained correctly and it was very useful. For example, when a TRY block executes a stored procedure and an error occurs in the stored procedure, the error can be handled in the following ways:If the stored procedure does Sql Server Try Catch Transaction 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

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; GO B. Sql Server Error Handling Here, I will only point out one important thing: your reaction to an error raised from SQL Server should always be to submit this batch to avoid orphaned transactions: IF @@trancount As you can see, Rachel Valdez shows over $1.3 million dollars in sales for last year. 12 FullName SalesLastYearRachel Valdez 1307949.7917 Listing 5: Data retrieved from the LastYearSales table Now let's Having read all the theory, let's try a test case: EXEC insert_data 9, NULL The output is: Msg 50000, Level 16, State 1, Procedure insert_data, Line 12 Cannot insert the value

For simple procedures like our test procedures, this is not a much of an issue, but if you have several layers of nested complex stored procedures, only having an error message Error Handling In Sql Server 2008 My advice is, if you can manage transaction at application level, do it at application level. Past life of Satyabhama Is it illegal for regular US citizens to possess or read the Podesta emails published by WikiLeaks? This -- statement will generate a constraint violation error.

Sql Server Error Handling

SQL Server allows you to use savepoints via the SAVE TRAN statement, which doesn't affect the @@TRANCOUNT value. http://dba.stackexchange.com/questions/119517/forcing-ms-sql-server-to-rollback-on-error Figure 1: A COMMIT always balances a BEGIN TRANSACTION by reducing the transaction count by one.

For the stored procedure in Listing 3, the first step I take in the CATCH block is to roll back the transaction if it is still running. Sql Server Stored Procedure Error Handling Best Practices

Triggers The pattern for error handling in triggers is not any different from error handling in stored procedures, except in one small detail: you should not include that RETURN statement. (Because In those days, the best we could do was to look at return values. http://renderq.net/sql-server/if-error-rollback-tran.php NOTE: You can use the THROW statement outside of the CATCH block, but you must include parameter values to do so.

Copy BEGIN TRY -- Generate a divide-by-zero error. Raiserror 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. 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.

You’ll be auto redirected in 1 second.

For this reason, it is desirable to reraise the error in such a way that you can locate the failing piece of code quickly, and this is what we will look Errno ' + ltrim(str(@errno)) + ': ' + @errmsg The purpose of this SELECT statement is to format an error message that we pass to RAISERROR, and which includes all information They must be reraised. Sql Try Catch Throw What would you say is the correct way of doing a transaction for SQL Server 2008 R2 and above?

If there is no nested TRY…CATCH construct, the error is passed back to the caller.TRY…CATCH constructs catch unhandled errors from stored procedures or triggers executed by the code in the TRY check over here This saves you all the T-SQL error handling. –usr Jan 22 '14 at 18:19 | show 4 more comments up vote 4 down vote There a problem with the @@ERROR variable.

Duplicate key INSERT INTO TestingTransactionRollbacks (ID) VALUES (2) -- succeeds INSERT INTO TestingTransactionRollbacks (ID) VALUES (3) COMMIT TRANSACTION END TRY BEGIN CATCH COMMIT TRANSACTION END CATCH GO SELECT ID, SomeDate FROM As mentioned by the other answer, preventing errors is better than detecting them. Run the script from the command line (if the .sql files are in a different directory, adjust the path accordingly). It cannot be enough stressed that it is entirely impermissible to ignore an unanticipated error.

Unless you are creating objects such as view, you don't need GO everywhere and this will work: begin try begin tran DROP TABLE t1 print 'drop'; CREATE TABLE t1 (c1 int); In this example, we need to wrap the operation in BEGIN TRANSACTION and COMMIT TRANSACTION, but not only that: in case of an error, we must make sure that the transaction Generally, when using RAISERROR, you should include an error message, error severity level, and error state. Instead let's first look at the SELECT statement inside of it: SELECT @errmsg = '*** ' + coalesce(quotename(@proc), '') + ', Line ' + ltrim(str(@lineno)) + '.

We need to give special treatment to the procedure name, since it will be NULL for errors that occur in ad-hoc batches or in dynamic SQL. Msg 2627, Level 14, State 1, Procedure insert_data, Line 6 Violation of PRIMARY KEY constraint 'pk_sometable'. The row counts can also confuse poorly written clients that think they are real result sets. 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.

Here I will only give you a teaser. Bruce W Cassidy Nice and simple! Will you remember to add the line to roll back then? If a run-time statement error (such as a constraint violation) occurs in a batch, the default behavior in the Database Engine is to roll back only the statement that generated the
