How Does Rollback Data Stored In SQL 2005?

Nov 23, 2007

Does anybody knows How does the rollback data stored in SQL 2005?

For example I am inserting 100 new rows into a table, so how does SQL keeps track of them as new rows which are yet to be committed?
Internally does SQL has any indexing to recognise the data which is not yet committed? Can we also write some queries on the table which will fetch us the non-committed insertions on the table?

If you have any clue about how does SQL 2005 handles this Rollback/Commit functions internally pls explain.

Regards,
Jacob

Saving Some Data Despite A Rollback Transaction Command

Sep 12, 2007



I am working on reformating, cleaning, adding derived elements, etc... on data with no data validity checks on the front-end, source data. Its an incremental process where each month I add new data to the prior months' history. Sometimes the new monthly source data "surprises" me -- different values, different data definitons, etc. than expected.

I deal with these surprises by accumulating the fields/values that are unexpected after converting them to varchar with some explanatory language into a table [program_newdataprobs]

If there are any records in [program_newdataproblem] I rollback the transactions so the prior months' history remains unaltered. The problem is I then "lose" the contents of [program_newdataproblem] which I would like to hand to the source data people to troubleshoot.

I have tried the following:


Begin Transaction tran1

.... code that reformats data here
if (select count(*) from program_newdataproblem)>0

BEGIN



Begin Transaction tran2

select * into #t1 from program_newdataproblem

Commit Transaction tran2

Rollback Transaction tran1

insert into program_newdataproblem
Select * from #t1


END


This bombs because because #t1 no longer exits

Any way I can "keep" the data from program_newdataproblem when I Rollback the other transactions? (without having to store the history in separate tables that I can then access if new data errors occur)

Thanks,

Rollback

Oct 17, 2007

The code inserts into table TABLES. TABLES has a primary key.
If the insert statement has no error it should insert 'ROWS INSERTED' to table CONTROL and update table DATETRACKING else insert 'ROWS NOT INSERTED' to table CONTROL and do not update table DATETRACKING.
1- I will like to improve my code if it is possible.
2- Can I use a rollback?

DECLARE @ROWCOUNT INT
DECLARE @ERROR INT
DECLARE @LASTDT DATETIME

SET @LASTDT =GETDATE()
BEGIN TRAN
insert tables
select 4

SELECT @ROWCOUNT = @@ROWCOUNT, @ERROR = @@ERROR
IF (@ERROR <> 0)
BEGIN
INSERT CONTROL
SELECT 'ROWS NOT INSERTED', @ROWCOUNT
END
ELSE
BEGIN
INSERT CONTROL
SELECT 'ROWS INSERTED', @ROWCOUNT
END
COMMIT TRAN

IF (@ROWCOUNT > 0)
BEGIN
UPDATE DATETRACKING
SET LASTDATEDL = GETDATE()
END

What To Do After A Transaction Rollback?

Dec 9, 2003

Hi!

I just made a transaction which writes and reads some data from a database as one unit. Now, I would like to know, what happens, if this transaction does not commit, but instead performs a rollback? Should I use a boolean loop which keeps on trying the transaction until it commits or is there an alternative? I would appreciate any suggestions or help!

Thanks!

Timeout On Rollback

May 17, 2004

I keep getting timeout expired when trying to rollback a transaction (have not tried to commit yet). The script hangs for around 30 secs, then fails.

Now, i've seen there's a command timeout for sqlcommands which defaults to 30 secs, but cannot find anything similar for sqltransaction...

Anyone can help?

SQL Transactions RollBack...

Dec 17, 2004

Hello:

I am just starting to falmiliarize myself with SQL transactions... I just created an SQL transaction... The first statement gets a value, if the value equals "" then the second statement executes... So if the value <> "" Then the second statement wont execute... What would happen in this scenario if the .Rollback is triggered? Heres my code:

Try
conSqlConnect.Open()
objTransaction = conSqlConnect.BeginTransaction
cmdSelect.Transaction = objTransaction
cmdInsert.Transaction = objTransaction
dtrdatareader = cmdSelect.ExecuteReader()
While dtrdatareader.Read()
varCheckNumber1 = dtrdatareader("Status")
End While
dtrdatareader.Close()
If varCheckNumber1 = "" Then
cmdInsert.ExecuteNonQuery()
End If
objTransaction.Commit
Catch
objTransaction.RollBack
Return "00"
Finally
If conSQLConnect.State = ConnectionState.Open Then
conSqlConnect.Close()
End If
End Try


Any Ideas?

Rollback Issue

Mar 30, 2001

Hello list,

I've some problem in SQL Server 7.0 and hope some one out there will help me with it. The problem is as follows:

When I view a proces in the process info screen, I see one process says "Rollback" in the status window and the spid is greyed out like a system process. In the command window it says, Select and wait type is "Exchange". This is taking too much cpu cycles and causing much of the server to perform very slow.

I tried to kill this session from the ISQL and Enterprise manager, But to still see this process running on with out getting killed. Also this process keeps coming.

Please advice me how to get rid of this and why is it ocurring again and again.

Thanks in advance.

Automatic Rollback

May 1, 2001

I am getting an automatic rollback in a transaction that fails to insert a row, via a trigger, due to a duplicate key. The transaction is automatically rolled back and unless the error correctly handled a 'partial update' occurs. Why in the example below is the transaction automatically rolled back (statements 1 to 3) and is there any way of knowing what errors generate an auto rollback. For example if the duplicate key error occurs on the insert into table B below, and not the triggered update, then no auto rollback occurs.

Begin Tran -- 1
insert into A values ('A1') -- 2 updates OK
insert into B values ('B1') -- 3 updates OK
-- triggers insert into B_Hist -- 4 Fails with Duplicate Key error
insert into C values ('C1') -- 5 updates OK
Commit Tran -- 6 3902 error No corresponding Begin

Thanks.

Rollback Process--please Help

Aug 16, 2000

Hi,

I have this weird situation on one of the production database.
Somebody ran a sql script couple days ago and must have hit cancelled. Somehow this script is still rolling back. The script is actually very simple statement..should not take more than couple miliseconds to run. Is there any way to see whether rollback is really in process or this process has simply hung? is there any other way to get rid of this rollback without stopping and restarting sql server services? Can it cause problems in getting sql server up again if I restart sql server services?

Rollback Optimization

Apr 28, 2000

This may sound a little silly, but does anyone have any words of wisdom on how to optimize a server/database for minimim rollback? We have some multimillion row tables we were trying to do updates against, and after several days they increased the size of the transaction log to the point they filled up the drive the database files/logs were on. We've now been running a rollback for about five days. I'd like to make sure this doesn't happen again.

What Will Happen -- ROLLBACK Or NONE?

Jul 14, 1999

Hi,

what will happen in the following occasion?

checkpoint --> begin tran --> system failure

In MOC (SQL 7.0 Implemetation), it says there will be rollback, but in my humbel opinion, there should be nothing happened.

I think there was no dirty writing in this case. No data pages written, no log
pages written to disk. Am I right? Then, there might be nothing happened
instead of ROLLBACK.

If I am wrong, would you please let me know what is wrong in my thougt?

Thanks in advance,

SQL Rollback Issues

Nov 20, 2004

Hello all,

I have been informed that most (if not some) RDBMS are faced with problems with the SQL ROLLBACK (also known as undo) command. I have been searching online, but have not found any useful relevant sources on what this issues are.

I am wondering if their are any experienced MS SQL Server (or any other RDBMS) users who might be able to provide feedback on this matter.
