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
Goofed up and ran an update query. It messed up all the data in a single table. I'm trying not to restore the table from a previous backup since the backup is more than 20 GB. It's going to take forever to restore it. Any advice would be much appreciated!
Thanks!

I have a fifty thousand record in a delimited file. while processing i got error in 45000th row. In database only 40000 records are there(why is there no all 45000 records). Is there any way to roll back all the 40000 records.
Hi,
I have an application that allows users to synchronize SQL CE data with the server. I would like to implement the functionality wherein if the synch process hits an error, the whole synchronization rolls back.
Is it possible to roll back the Synchronization process? I am using Merge replication over web in the application.
Thanks

Hi,
I'm planning to install the cumulative hotfix (build 2187) on my sql 2000 clustering server (SP4, 2040). And I would like to know if the cumulative hotfix is able to roll back. If possible, please provide me any information about that. Thanks in advance.
what will happen if power breaks down during replication. Did the replicated data be rolled back ?
If data is not rolled back then how to roll back ?

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.
I have a script contains multiple statements to update multiple tables. How can I make sure that either all statements get executed successfully or no changes apply to the tables (in case one or more errors occur)? I've been searching on Internet and it seems like I need to use Rollback and begin transaction.

I have a situation where i need to insert or update the data from a flat file to a sql server database. The flat file contains nearly one lakh records.
I am using transactions. If all the rows are inserted or updated successfully i am commiting. If there is any error i am rollbacking the transaction.
when rollbacking the transaction it is taking more than 3 to 4 hours.
Can any one suggest me how to do that in batches?
Thanks in Advance

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.
Hi all,
I'm getting the following error message in NT event view:
Error: 9002, Severity: 17, State: 2
The log file for database 'db_sys' is full. Back up the transaction log for the database to free up some log space.
But I don't know how to back up the transaction log for the database.
Do I need TRUNCTE LOG (in E.M) to free up some log space?
I only know back up all the database using ALL TASKS -> BACKUP DATABASE in E.M. Please help me. Thanks in advance.

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

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
Ive got an insert statement that fails, and below that I have code like the following:
IF @@ERROR <> 0
BEGIN
-- Roll back the transaction
ROLLBACK
-- Raise an error and return
RAISERROR ('Error INSERT INTO Address.', 16, 1)
print 'test was here'
RETURN
END
However, there is now rollback and the inserts below it are going through.
what do i have wrong ?
The following transaction runs, then reverts back after 10 mins.
begin Tran [UpdateSundays]
update ScanAssetInformation with (rowlock)
set BusinessDate = dateadd(day,-2,BusinessDate)
where datepart(weekday,BusinessDate) = 1
commit tran [UpdateSundays]
begin Tran [UpdateSaturdays]
update ScanAssetInformation with (rowlock)
set BusinessDate = dateadd(day,-1,BusinessDate)
where datepart(weekday,BusinessDate) = 7
commit tran [UpdateSaturdays]
hi,
i want to create a disaster recovery site, to which i can fail over (not automatically),
and also to have the option to return the database to a point in time?
for example,
if my principal server fails in 17:00,
i want to have the option to make the mirror server available for users from 17:00 (or at least close to that time),
and also to be able the return to the data from 16:00 (in the mirror site).
Is it possible, and what is the best way to do it?
Thanks.
When using the maintenance plan to backup t logs, should I enclude the system database logs such as master, model, etc...?

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
Ahmed

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'
GO
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.
thanks.
Hi,
Is there a way to write to a log-table inside a transaction which is rolled back without rollback of this log-entry.
thanks in advance

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 :
begin transaction
save transaction t1
delete from #t1
save transaction t2
begin try
delete from #t2
[Code] ....
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.
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.

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.
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?
Can I roll back certain query(insert/update) execution in one page if query (insert/update) in other page execution fails in asp.net.( I am using sqlserver 2000 as back end)
scenario
In a webpage1, I have insert query into master table and Page2 I have insert query to store data in sub table.
I need to rollback the insert command execution for sub table ,if insert command to master table in web page1 is failed. (Query in webpage2 executes first, then only the query in webpage1) Can I use System. Transaction to solve this? Thanks in advance
