SQL Server 2008 :: Can Second Save Transaction T2 Be Rolled Back
May 4, 2015
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.

Hi all,
Sometimes when I do "alter database ABCD set partner failover" I get the following message: Nonqualified transactions are being rolled back. Estimated rollback completion: 100%.
In 99 percent of the cases after such message the first attempt to use an open connection would also raise an error such as "Exception: A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"
After the first error all subsequent queries would run perfectly.
What am I missing?

I have a person table
CREATE TABLE Person
(
PersonID INT
Name varchar(50),
HireDate datetime,
HireOrder int,
AltOrder int
)
Assume I have data like this
INSERT INTO Person VALUES(1, 'Rob', '06/02/1988', 0, 0)
INSERT INTO Person VALUES(2, 'Tom', '05/07/2016', 0, 0)
INSERT INTO Person VALUES(3, 'Phil', '01/04/2011', 1, 0)
INSERT INTO Person VALUES(4, 'Cris', '01/04/2011', 2, 0)
INSERT INTO Person VALUES(5, 'Jen', '01/04/2011', 3, 0)
INSERT INTO Person VALUES(6, 'Bill', '01/05/2011', 0, 0)
INSERT INTO Person VALUES(7, 'Ray', '01/23/2012', 0, 0)
I'm trying to simplify my requirement... providing the input of HireDate, HireOrder, and AltOrder, I need to be able to pick up the next person
For ex:, if I provide input, HireDate: 06/02/1988, HireOrder:0, AltOrder:0, the return value expected is "Tom" because he is the next person after the provided input.
For ex:, if I provide input, HireDate: 05/07/2016, HireOrder:0, AltOrder:0, the return value expected is "Phil" because he is the next person after the provided input. Though Phil and Cris have same dates, their HireOrder takes precedence in this case. If they also have same HireOrder, AltOrder would be coming in picture to determine next person
Another ex: if I provide input, HireDate: 01/04/2011, HireOrder:1, AltOrder:0, the return value expected is "Cris" because she is the next person after the provided input. Here hireorder determines.
If I provide, HireDate: 01/23/2012, HireOrder:0, AltOrder:0, as there is no person after this, I should be able to pick the first person on the list - in this case Rob.
I can write some business logic in front-end, but I thought it would be good, if I can move this to a stored procedure which can return me the PersonID for optimal performance.
I have tried writing various conditions but couldn't achieve a query that meets all my requirements here.
I'm even fine if my last condition is not met (returning the first person in the list, in case no one is available after the provided input).

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?

I received alerts from a couple of the production servers last night stating that the log file is running out of space. So, I took some log backups and shrunk those files. However, I would like to find out what made the log grow like that. After all, I have t-log backups scheduled every 30 minutes.Is there a way I can find out the reason behind the log growth?

Currently, we are on SQL2008R2 EE SP1 CU13 across the board.
We are planning on upgrading the primary SQL server to SP3.
Question: Will transactional replication continue to work properly even if the Publisher is upgraded to SP3 but the subscribers remain at SP1 CU13 ?

I am trying to reorganise the log files on a server, (long story short they are fragmented so I want to shrink and reset the initial size and growth) and I am unable to shrink them. When I run the following:
use test
DBCC SHRINKFILE(test_log, TRUNCATEONLY)
--or
use
DBCC SHRINKFILE(test_log,2, TRUNCATEONLY)
I get the following message:
Msg 8985, Level 16, State 1, Line 1
Could not locate file 'test_log' for database 'test' in sys.database_files. The file either does not exist, or was dropped.
I get this message for every database on the server. I got the logical name of the file using sp_helpfile and have checked it against sys.masterfiles, sys.database_files and sys.sysaltfiles, all match up and confirm the name 'test_log'.
I rebooted the server last night and was able to shrink the first couple of .ldf's I tried so I presumed it was fixed. This morning when I try again i get the sanme error, I don't see anything in the SQL server or system logs that indicates a change.
I am able to add new log files and remove log files, however if I add a new log file (test_log2) and then try and truncate that file I get the same error.

Having a lot of problems with backup device creating backups with a new transaction log for each day. This is causing the backups to grow way to fast. Seems to be random with our clients. Created new device backups but getting same problem. A manual backup selecting overwrite all existing backup sets will fix it. But starts the cycle all over again.

I have two tables one list changes of hospital ward and one lists changes of consultant doctor. These can change independently ie a ward change can occur without a consultant change and vice versa. I want to summarise these changes to give the status at each date_serial value.
create table #temp_ward_stay(date_serial bigint,ward_id varchar(10))
;
insert into #temp_ward_stay
values
(201501021200,'W1'),(201501031201,'W2'),(201501091200,'W3'),(201501161200,'W4'),(201501161201,'W5')(201501271200,'W3'),(201502101200,'W5')
;
create table #temp_consultant_episode(
date_serial bigint,
consultant_id varchar(10))
;
insert into #temp_consultant_episode values
(201501021200,'C1'),(201501031200,'C2'),(201501031201,'C3'),(201501091201,'C4'),
(201501121200,'C3'),(201501301200,'C6'),(201502111200,'C6'),(201502111201,'C7')
;
If I use:
select date_serial,consultant_id,null as ward_id from #temp_consultant_episode
union
select date_serial,null as consultant_id,ward_id from #temp_ward_stay
I get:
date_serial ward_id consultant_id
-------------------- ---------- -------------
201501021200 NULL C1
201501021200 W1 NULL
201501031200 NULL C2
201501031201 NULL C3
201501031201 W2 NULL
201501091200 W3 NULL
201501091201 NULL C4
201501121200 NULL C3
201501161200 W4 NULL
[code].....
whereas what I actually want is:
date_serialward_idconsultant_id
201501021200W1C1
201501031200W1C2
201501031201W2C3
201501091200W3C3
201501091201W3C4
201501121200W3C3
201501161200W4C3
201501161201W5C3
[code].....
I can see how I could remove the nulls where the date_serial values are the same:
select ce.date_serial,ward_id,consultant_id from #temp_consultant_episode ce
join #temp_ward_stay ws
on ce.date_serial=ws.date_serial
but I can't see how to move forward from here.

So if you execute as so:/* START CODE SNIPPET */Begin Tran--Execute Stored ProcExec dbo.TestSaveTran/* END CODE SNIPPET */There is no "Cannot roll back LOCALTRAN...." message.Questions:1-)Can someone confirm save point names are case sensitve and this isnot happening because of a server setting?2-)Is this a logic error that I am not seeing in the example codeabove?We have changed our code to store the save point name in a variable,which will hopefully mitigate this "problem".Thx.

I've re-written a stored procedure and when I post the following codeinto the existing SP in EM, is saves OK. However, when I re-edit theSP, the last line 'Commit Transaction' has been removed.I cannot save the remainder of the SP as it throws error 208 (InvalidObject name #Max) about two of the temp tables I use when I post theentire script. It shows in a message box with the header : 'MicrosoftSQL-DMO(ODBC SQLState:42S02)I haven't posted the full SP nor the structure as it's quite large(2000 lines), so hopefully I have given enough detail, but my questionsare :Why does it now have problems with (temp) #Tables ? The use of thesehas not changed. All I have done is wrap the script into varioustransactions as this helps a lot for performance and tweaked a fewparts later in the SP again for performance.Also, why does the line get removed once I save the SP ?If I run this in QA, I get the same errors, so I suspect it's myscript, but don't know where I'm going wrong.SQL2000 (Need to upgrade the service pack as recently installed on myPC, so this may help)Thanks in advanceRyanCREATE PROCEDURE [dbo].[JAG_Extract] (@ExtractYear INTEGER,@ExtractMonth INTEGER) ASBEGIN TRANSACTIONSELECT 0 AS MaxYear, 0 AS MaxMonth INTO #MaxUPDATE #Max SET MaxYear = @ExtractYearUPDATE #Max SET MaxMonth = @ExtractMonthPRINT 'Stage 1 - ' + Convert(VarChar, GetDate())CREATE TABLE #Extract ([DEALER_SOURCE_DATA_ID] INT,[DSD_YEAR] INT NULL,[DSD_MONTH] INT NULL,[DEALER_CODE] VarChar(20),[FranDealerCode] VarChar(20) NULL,[Line_No] VarChar(75),[Current] [numeric](15, 5) NULL,[YTD] [numeric](15, 5) NULL,[12Months] [numeric](15, 5) NULL,[24Months] [numeric](15, 5) NULL,[Average_YTD] [numeric](15, 5) NULL,[Average12Months] [numeric](15, 5) NULL,[Average24Months] [numeric](15, 5) NULL,[Last_YTD] [numeric](15, 5) NULL,[Current_STATUS] INT,[PD1] [numeric](15, 5) NULL,[PD2] [numeric](15, 5) NULL,[PD3] [numeric](15, 5) NULL,[PD4] [numeric](15, 5) NULL,[PD5] [numeric](15, 5) NULL,[PD6] [numeric](15, 5) NULL,[PD7] [numeric](15, 5) NULL,[PD8] [numeric](15, 5) NULL,[PD9] [numeric](15, 5) NULL,[PD10] [numeric](15, 5) NULL,[PD11] [numeric](15, 5) NULL,[PD12] [numeric](15, 5) NULL,[PD13] [numeric](15, 5) NULL,[PD14] [numeric](15, 5) NULL,[PD15] [numeric](15, 5) NULL,[PD16] [numeric](15, 5) NULL,[PD17] [numeric](15, 5) NULL,[PD18] [numeric](15, 5) NULL,[PD19] [numeric](15, 5) NULL,[PD20] [numeric](15, 5) NULL,[PD21] [numeric](15, 5) NULL,[PD22] [numeric](15, 5) NULL,[PD23] [numeric](15, 5) NULL,[PD24] [numeric](15, 5) NULL,[PD25] [numeric](15, 5) NULL,[PD26] [numeric](15, 5) NULL,[PD27] [numeric](15, 5) NULL,[PD28] [numeric](15, 5) NULL,[PD29] [numeric](15, 5) NULL,[PD30] [numeric](15, 5) NULL,[PD31] [numeric](15, 5) NULL,[PD32] [numeric](15, 5) NULL,[PD33] [numeric](15, 5) NULL,[PD34] [numeric](15, 5) NULL,[PD35] [numeric](15, 5) NULL,[PD36] [numeric](15, 5) NULL)INSERT INTO #ExtractSELECT DISTINCTSD.DEALER_SOURCE_DATA_ID,SD.DSD_YEAR,SD.DSD_MONTH,DN.DEALER_CODE,DN.FRAN_DEALER_CODE,DV.FIELD_CODE,0,0,0,0,0,0,0,0,SD.STATUS,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0FROMDEALER_NAW DN WITH (NOLOCK)INNER JOIN DEALER_SOURCE_DATA SD WITH (NOLOCK)ON DN.DEALER_CODE = SD.DEALER_CODEINNER JOIN DEALER_SOURCE_DATA_VALUES_Current DV WITH (NOLOCK)ON SD.DEALER_SOURCE_DATA_ID = DV.DEALER_SOURCE_DATA_IDAND SD.STATUS < 4096INNER JOIN DEALER_FIXED_GROUP_RELATION GR WITH (NOLOCK)ON DN.DEALER_CODE = GR.DEALER_CODEAND GR.FIXED_GROUP_ID IN(11,12,13,14,15,16,17,18,23,42,43,44,45,46,47,48,4 9,50,51,52,53,54,55,56,57,58,59,60,61,106,109,110,111,1 12,113,114,115,130,131,132,133,134,135,136,137)GOCOMMIT TRANSACTION

Currently we has a database of size about 300G. Because our backup system failed some time past we were left with a transaction log file which grew to about 160G. However our backups are working again and everything is working fine. My understanding is that now the transaction log file is practically empty but the capacity remains at 160G.
When you delete records the deleted transactions are going to get logged to the transaction file. My understanding is when a backup is done these transactions get discarded out of the transaction file.
could I make use of this relatively large transaction file and start deleting transactions without out actually adding to the transaction file size.
The plan is to delete records from logging tables that are not referenced to by any other table without this increasing the transaction log file.For example over a period of a few weeks we can delete a chunk of records from a table. Then after it has completed a backup we can delete another chunk of records out of this table until we have got the table down to the records that we now need.Will this work?

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.

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

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?

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.

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.

Does anybody know of a way to rollback SQL Server 2005
databases back to SQL Server 2000? Is there a way of doing it without
resorting to Copy Database Wizard? I love to find a way of attaching a SS 2005 database
to a SS 2000 instance without any issues.
I recently upgraded to SS 2005 and I am very unhappy with the SS 2005 and I
want to rollback to SS 2000, which was a lot more stable. I am having
several major issues that are affecting my whole company's day-to-day
operations and the managers are not happy. Some of the issues include
night time batch running very sluggish for no apparent reason. This is a
biggest problem because it only occurs once or so a week and causes a disturbance
with the daily activities when the night time processing isn€™t completed on
time. The rest of the time, the batch processing runs great, even a little better then on SS 2000. I
don't believe it is a matter of my application needing to be retuned because if
that was the case, then why isn't it running sluggish every night? Also,
it's never the same day that the sluggish behavior occurs. If it was occurring
on the same night, then I would have something to investigate within our
application, but it doesn't. Another issue that I am having involves a
night time job that restores a copy of the production database to the Data
Warehouse server to be used for updating the data warehouse. Again, most
of the time it runs great (~2 1/2 hours), but once or twice a week, it goes
stupid and takes 6 1/2 hours for no apparent reason. Again, it is not happening
the same day either, which could give me something to invesigate. On SS 2000, this same job ran flawlessly. Never I did I run into situation that the
database restoration took that long to run. Even another issue involves a SQL Server Agent Job that was put into suspended
state. What's a suspended state and how can I get it out of suspended
state? I can find no information about suspended state in BOL. I
did a Google and nothing came up. If this suspended state was put
in for security reasons, great, but then tell me how I can remove the suspended
state. I am also not happy with the
fact that I can't get accurate information about the queries that are actively
running at that particular moment. In SS 2000, when I noticed high CPU
usage on the server, I would run the sp_who2 active stored proc and it would
show me all the active thread and how much CPU it was consuming. I would
then find the running threads with the highest CPU numbers and investigate the
query and see if we could improve it. Now in SS 2005, I get in the same
situation and run the sp_who2 stored proc, and there is no smoking gun.
All of the active threads are showing very little CPU usage, which I am very
suspect of. What the heck happen to sp_who2? I looked at some of
the other ways of looking at running processes (i.e... sys.sysprocesses) and
they don't appear to be giving the information that I need.
I am very unhappy and I just want to roll back to SS 2000 and wait a couple of
years before I upgrade to SS 2005.

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()
