Hi,
Can I rollback a database if I have transaction logs?
For example, I want to rollback the database without all the transactions that occurs within the last 10 days.
Thank you.
I tried killing a rollback several times, but it would not disapear.
I came back the next day, it is still there.
Anyone knows how to get rid of a rollback?
Thanks in advance.
Hi:
I have rollback on one of the users. I tried killing
her process through Enterprise Manager and Query Analyzer,
but I still can see her process on the screen. However, her
login is grayed out after I execute the kill query.
I have encountered this problem several times, and the only way
I can get clear the rollback is by rebooting the server.
Does anyone have a sugeestion on how to clear the rollback
without rebooting.
Please advise if you have any suggestion.
Thanks in advance.
Hi All
A question on DTS ROLLBACK CAPABILITY.
Is it possible to setup a DTS pkg to roll back the loaded files if a step fails?
If a step fail records inserted by Data Pump to a table should be removed.
Is this possible? If so how can we achieve this?
Any advice is appreciated.
Thanks

hi friends,
is it possible to roll back a transaction here? i heard that it will be possible only if we wrote the code only in certain block.please tell me the block.
vinod
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

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!

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?
Thanks. -julio
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?
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.

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.
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?
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.
View 1 Replies View RelatedHi,
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,
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.

Don't ask, but I iadvertantly managed to delete 57,000+ records in the EM console and I need to roll back the database a few minutes to recover said information. I do not care about transactions that have occured since due to shutting the system down immediately upon realizing what I did. I have however never had the need to roll back the database before, so I have experience doing so. Any help is desperately needed and greatly appreciated!!!

Bit of a puzzler...
A customer of ours has reported a intermittent error using one of our applications to receive some stock.
Under normal circumstances the application updates about 10 tables in a single transaction, inserting to some, updating others. After the stock receipt they print off a Crystal report against the receipt data.
The customer is saying that (very) occasionally they perform a receipt (no errors) and print off the report (no problems) yet when they come to access the data some time later it is almost as if no receipt has been made.
I have seen their data and can see what they mean. None of the expected data updates seem to have taken place. And yet there is the report sat there, indicating that it must have...
Looking closely at the data I can see breaks in the sequencing in certain identity column-carrying tables, during the period when the stock receipt was made. To all intents and purposes, therefore, it looks as though a rollback has occurred.
Is this possible? Could a Crystal report show uncommitted data which is then rolled back? How 'long' can a rollback take? Can it be initiated in some other way?
NB: We have done all the obvious things like:
- checking they have received against the correct DB;
- checking that no app or procedure can remove data in this way.
- verified that the report is reporting from the correct place.
etc.
The 'missing' data is so perfectly removed, my instinct says it must be a rollback but I can't see how this can be (yet).
All suggestions gratefully received - how could I track down whether this was occurring? Or is it my fevered imagination?
Many thanks!!!!

ps: According to our records, this customer is running SQL 7 SP3.
How do I find out the transaction name to rollback. Thanks
View 1 Replies View RelatedI am not sure about the ANSI/ISO rules on this? We have a SEQUENCE and insert it into a table.
CREATE SEQUENCE Cheque_Seq
AS INTEGER
START WITH 1
INCREMENT BY 1;
CREATE TABLE Cheque_Book
(cheque_seq INTEGER*NOT NULL PRIMARY KEY,
cheque_amt DECIMAL (15,2) DEFAULT 0.00 NOT NULL);
If I do an insertion with the SEQUENCE in a transaction and then ROLLBACK the transaction, what happens to the sequence value? My thought is that the value should reset to the state it was in before the transaction (basic definition of a ROLLBACK). But it does not in the products I have looked at.
I tried adding columns to a table on a database manually. Unfortunately the database doesnt have a lot of free space, and on saving the columns, it was slowly running out of space. I made the decision to end the (sql enterprise) task via task manager. I am now unable to get into enterprise... I am assuming it is trying to rollback?<>?. can anyone tell me what happens next. will the database still be intact..
thanks
