Transaction Scope Rollback Does Not Roll Back Action Of Activation SP

Aug 16, 2007

Hi,

I followed Remus' post about not doing 'fire and forget'.

I have two queues, ProcessingSendQueue and ProcessingReceiveQueue.

Once i receive from ProcessingReceiveQueue, activation SP gets called on ProcessingSendQueue and ends conversation.

However,if I then get an exception, the action of the activation SP ( ie the ending of the conversation ) does not get rolled back... is this possible? I would have thought that the action of the activation SP would get rolled back too.

My ProcessingSendQueue activation SP is as follows:

ALTER PROCEDURE [dbo].[ProcessingSendQueue_AP]
AS
BEGIN
DECLARE @dh UNIQUEIDENTIFIER;
DECLARE @message_type SYSNAME;
DECLARE @message_body NVARCHAR(4000);

RECEIVE @dh = [conversation_handle], @message_type = [message_type_name], @message_body = CAST([message_body] AS NVARCHAR(4000))
FROM [ProcessingSendQueue];

IF @dh IS NOT NULL
BEGIN
IF @message_type = N'http://schemas.microsoft.com/SQL/ServiceBroker/Error'
BEGIN
RAISERROR (N'Received error %s from service [ProcessingReceiveQueue]', 10, 1, @message_body) WITH LOG;
END
END CONVERSATION @dh;
END
END

How To Get IDENTITY_INSERT Incriment Primary Key ID Roll Back When The Application Fails.

Oct 28, 2007

 My question is how to get IDENTITY_INSERT Incriment Primary Key ID  roll back when the application fails.
Using TransactionScope with single connection in DataObject. I am trying to insert row in two dataTable  using its own tableAdapter (two tableAdapter).
I have Product table with ProductID primary key with incriment identity.  and that ProductID is used to insert row in ProductHistory Table. Lets say Product table has the last ProductID=8 (8 rows) and the next ProductID will be 9.
When I insert row in both table and if the second table insert fails both gets roll back (which is good). but when I insert again another time the Product ID=10 not 9. Is there any way to roll back the ProductID in Product table so when i insert next time it has incriment number instead of gap.

How To Implement Alter Database Implement Restrictions On SQL2K ?

Dec 28, 2007

Hi Guyz

it is taken from SQL2K5 SP2 readme.txt. Anyone have idea what to do to implement this ?
Our sp2 is failing. we suspect the above problem and researching it.we are running on default instance of SQL2K5 on win2003 ent sp2

"When you apply SP2, Setup upgrades system databases. If you have implemented restrictions on the ALTER DATABASE syntax, this upgrade may fail. Restrictions to ALTER DATABASE may include the following:

Explicitly denying the ALTER DATABASE statement.


A data definition language (DDL) trigger on ALTER DATABASE that rolls back the transaction containing the ALTER DATABASE statement.


If you have restrictions on ALTER DATABASE, and Setup fails to upgrade system databases to SP2, you must disable these restrictions and then re-run Setup."

thanks in advance.

Transaction Not Rolling Back

Mar 19, 2007

I have a stored procedure that calls another stored procedure with thefirst stored procedure opening a transaction:BEGINSET XACT_ABORT ONBEGIN TRANSACTIONdoes various updates/insertscalls 2nd stored procedure to proccess updates/inserts common to manyother stored proceduresdoes more various updates/insertscommitENDThe problem I'm having is that within the 2nd stored procedure is thatif it encounters an error, it does not roll back the entiretransaction and I finish up with missing records in the database. Amusing this in the 2nd stored procedure:if(@TypeId1 = @TypeId2 and @Line1 <'' and @Line2 <'')beginRAISERROR('error message', 16, 1)RETURNendWhat could the problem be? From what I've read, it seems as thoughyou can't have an open transaction within one sp that calls another spand it maintains the same transactoin? Is this corrrect?I tired the following too, and I still couldn't get it to work. Anyideas anyone?************ sp 1 ***********Declare @AddressError char(3)SET XACT_ABORT ONBEGIN TRANSACTIONexec Sp2@AddressError OUTPUT,@variable1,@variable2,etc. etc************** sp 2 *****************@AddressError char(3) OUTPUT,if(@TypeId1 = @TypeId2 and @Line1 <'' and @Line2 <'')beginRAISERROR('error message', 16, 1)RETURNendSET XACT_ABORT ONBEGIN TRANSACTIONprocess updates/insertsSet @AddressError = 'no'Commit******** back to sp 1************If @AddressError <'no'BEGINrollback transactionENDcontinue doing updates/insertscommit

Rolling Back Transaction

Jun 16, 2007

Hi,



I have a case where I read from SQL Server DB and write to a flat file.

I have one Data Flow Task inside which I have a OLEDB source component that feeds rows to a script component that writes to a flat file. I have set the txn attributes for the container to "Required" and "Read committed" . But I find that rows are written to flat file even when I throw an exception from my script component. Question is how do I prevent rows from being written to the flat file if error/exception happens. I want the whole process to be in a single transaction.



Thanks

Back Up And Restore Using Transaction Log And Incremental Backup

Feb 1, 2001

hi, I would like to know the correct reaction for a crash in both senarios.
First senario,
I made a full back up at 6 am , then scheduled sql server to make transaction log back up every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 12:30. How would I resotre the data in the first senario....Can I restore the full back up done at 6 am then restore the last transaction log backup ( which is 12 Noon ) . I am not sure If I need to resotre the whole tran from 6 am till the time it was crashed.

Second senario,

I made a full back up at 6 am, then scheduled sql server to make Incremental backup every 2 hours (8,10,12,2 pm,4,6,8) . If I have a crash at 3:00 pm. How would I resotre the data in the second senario. ....Do I restore the full backup at 6 am then restore each incremental backup backwords ( 2,12,10,8)

AS you can see, I am not sure how to deal with this issue, I do appreciate your feedback.

Best regards

Feb 3, 2004

I have a Development database and I want to roll it back to Monday morning. I backed up the database and used the command:

RESTORE DATABASE ITTEST
FROM ITTEST20040203
WITH NORECOVERY
GO

RESTORE LOG MyNwind
FROM ITTEST20040203
WITH RECOVERY, STOPAT = 'FEBRUARY 2, 2004 09:00 AM'

The transaction logs have never been truncated.

But it does not seem to have worked. It this the best way to do a roll back the database or have I missed out something.

Rolling Back Transaction After .Commit() Runs Successfully

Jun 10, 2007

I have a page that runs a transaction correctly after a button click.
I want to allow someone to click a button that rolls back the transaction, after the transaction runs on the first button click.
I can also successfully roll back within the first button click.
 I'm getting a NullReference error when trying to access SqlTransaction.Rollback() outside the button click.
 If SqlTransaction.Commit() completes without error can SqlTransaction.Rollback() be called after?
I tried making 'trans' a more global variable and it still gave me the error.
Button Click 1:
Dim trans As SqlTransaction
trans = connection.BeginTransaction()
try
'run SQL Statement
trans.Commit()
Catch e As Exception
 trans.Rollback()
throw e
end try
 
Button Click 2:
trans.Rollback()

I am confused about save transaction in the below scenario :

delete from #t1
save transaction t2

If there is error after delete #t2 , transaction t1 is rolled back. But i am not able to understand why i am getting error in the statement 'rollback transaction t2' . I am getting error as 'Cannot roll back t2. No transaction or savepoint of that name was found.'. but save point t2 is mentioned in the code.

Transaction Replication Failed After Restoring Full Back Up Of Database In NORECOVERY

Mar 4, 2011

We had a siutation last night in our production environment that forced us to revert back to an earlier version of the database (before a major code rollout that failed). After restoring the days full backup (with NORECOVERY), and then restoring a DIFF backup (FULL RECOVERY and had checked Preserve Replication Settings)...the transaction replication failed.

Message #1
The replication agent has been successfully started. See the Replication Monitor for more information.

I've tried reinitializing the publication/subscription and while that took brand new snapshots and copied it over to the replicated data server, it did not fix the problem.I read from a different post that I could try running "sp_replrestart" but that ran for about a half an hour and didn't appear to do anything but fill up our log files...did I not wait long enough?

The only thing I know to do at this point is to drop the publication on the production server and rebuild it completely (and with all the tables we're replicating that would take quite a bit of time.

SQL Server 2014 :: Stored Proc Timing Out Halfway Through - Rolling Back Without Transaction

Jul 7, 2015

We have a high volume database with 1000's of users and 1000's of procs. Our application enforces a 20 second timeout on all connections.

We can't adjust the 20 seconds - this is a business rule.

It sometimes happens that a proc does not complete within 20 seconds and then times out halfway though. This causes data inconsistency where 50% of the code was saved to the DB and 50% was not - seeing that a stored proc is not transactional and therefor does not roll back the code.

We can't put the code in a TRANSACTION in order to roll back when a time out occurs, because this causes exclusive locks on the tables.

So I guess my question is:
Is it possible to undo/rollback all the code in a proc when a timeout occurs - without using a TRANSACTION? And if a TRANSACTION is the only way - how do I avoid the exclusive lock and blocks?
