Transaction Management

Oct 4, 2005

Let's say I may possibly use two transactions in a script, the second
one will depend on the successful execution of the first one.

The following code works. However, I'm wondering if SQL Server 2000
has some internal function like @@transaction_status to indicate the
status of the most recent transaction by the connection. The analogue
of @@FETCH_STATUS. Then, my own error tracking code could be omitted.

Thanks.

-- ENV: SQL Server 2000
-- ddls
create table tblA (col1 smallint, col2 smallint)
create table tblB (col1 smallint, col2 smallint)
create table tblX (col1 char(1), col2 varchar(20))

declare @errorCode tinyInt
set @errorCode = 0

begin transaction fTran
insert into tblA
values (7,1);

insert into tblB
values (8,0);

-- we know this guy will fail
insert into tblX
values ('ab','abcdefge')

If (@@error <> 0)
begin
select @errorCode = 1
end

if (@errorCode = 1)
rollback transaction fTran
else
commit transaction fTran

if (@errorCode = 0)
pseducode: start second transaction here ...
else
print 'fTran failed.';
RETURN

Transaction Log Management

Dec 13, 2007

Hi,

I'm new to MS SQL and would like to get your opinion on how it's possible to automatically manage transaction log growth. I've read the following on the topic:

"When Microsoft SQL Server finishes backing up the transaction log, it truncates the inactive portion of the transaction log. This frees up space on the transaction log. SQL Server can reuse this truncated space instead of causing the transaction log to continuously grow and consume more space. The active portion of the transaction log contains transactions that are still running and have not completed yet."

I'm backing up the transaction logs on a daily basis. Still one of the logs grew up to 130Gb even though I have shrunk it in the past. How can I manage the growth automatically without shrinking the log files manually every time they grow beyond a certain threshold?

Thanks in advance,
Alla

Still one of the logs grew up to 130Gb even though I have shrunk it in the past. How can I manage the growth automatically without shrinking the log files manually every time they grow beyond a certain threshold? Also, how can I check whether some of the log portions are active or inactive?

Transaction Definition/Server Management

Dec 4, 2000

I need to keep a table indicating the number of "transactions" or Logical Units of Work (LUW) against each database each day. I know transactions are defined with a Begin and End statement but most of our software is from 3rd party vendors who don't use begin and end. How can I determine how many transactions (not necessarily I/O although that might be nice in the future) has occurred against each database. Books On Line does not address the question of transactions other than to say use the Begin/End statments. Any thoughts would be greatly appreciated.
Thanks in advance

SSIS Transaction Management &&amp; Strange Deadlock When Using XLOCK, ROWLOCK

Jun 7, 2007

I have a SSIS package that is run from one job, nowhere else. The package has TransactionOption NotSupported.



In the SSIS package I first have a sequence container that has TransactionOption Required (Serializable). The sequence container contains several Execute SQL tasks that access the same SQL Server 2005 database. The Execute SQL tasks have TransactionOption supported / Serializable. The first SQL statement is:



select p.column_name

from table_name p with (XLOCK, ROWLOCK)

where p.second_column_name = 'COLUMN_VALUE'



After this there are a couple of SQL tasks, and finally a task containing the following SQL:



select p.third_column_name

from table_name p

where p.second_colomn_name = 'COLUNM_NAME'



The idea is that the first query exclusively locks the row in the table_name-table for mutual exclusion purposes, i.e. so that if for some reason the SSIS package would be executed simultaneously two or more times, only one package execution could lock the row and proceed and the other executions will have to wait. There's an index on column second_column_name in the table to avoid the select locking other rows in addition to the required row.



Some questions:

1) Is it so in my setup that when SSIS runtime executes the sequence container it creates a transaction in the beginning of the sequence container and commits the transaction in the end of the sequence container? And in my setup the Execute SQL tasks in the sequence containar are executed under the same transaction?

2) I have a problem that the second query sometimes gives this error:"ErrorCode: -1073548784. ErrorDescription: Executing the query "XXXXX" failed with the following error: "Transaction (Process ID 73) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly."

The 1st query has locked the row for the transaction. How can the second query be deadlocked, shouldn't the transaction have a lock on the row? I'd understand if the 1st query failed sometimes, but don't understand how the 2nd quey can fail.

Error 8525: Distributed Transaction Completed. Either Enlist This Session In A New Transaction Or The NULL Transaction.

May 31, 2008

Hi All

I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.

If I take away the begin tran and commit it works, but of course, if one statement fails I want a rollback. I'm executing this from a Delphi app, but I get the same from Qry Analyser.

I've tried both with and without the Set XACT . . ., and also tried with Set Implicit_Transactions off.

set XACT_ABORT ON
Begin distributed Tran
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.TRANSACTIONMAIN
set REPFLAG = 0 where REPFLAG = 1

SQL Server Management Express Studio Management Tools

I have recently installed the SQL Server Management Studio Express but I do not find Management Tools in order to create scheduled backups and shrinking of the databases. I was under the impression that this should be included in the Management Studio. I use the SQL 2005 Express for smaller customers who run the SQL on a desktop unit. I need a way to backup the data to a server machine for backup purposes. I have uninstalled and reinstalled to no avail.

TRANSACTIONS In SSIS (error: The ROLLBACK TRANSACTION Request Has No Corresponding BEGIN TRANSACTION.

Nov 14, 2006

I'm receiving the below error when trying to implement Execute SQL Task.

"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'

I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.

Anyone know of the reason?

Analysis :: Find Amount Distribution Across Different Transaction Types Under Spend Transaction

Jul 27, 2015

I created a Calculated measure in cube something like this : ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount]). To get only spend transactions. Now, I want to slice this measure with same hierarchy to find the amount distribution across different transaction types under spend transaction. But this query behaving like the measure doesn't have relation with measure.

you can think this as below query:
WITH
MEMBER SPEND AS ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount])
SELECT NON EMPTY {SPEND} ON 0
,NON EMPTY ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent]) ON 1
FROM [CUBE]

Problem With SSIS Transaction...Transaction Scope

Jun 1, 2006



Hi,

I am having some problem with SSIS transaction. Eventhought I tried to imitate the concept that Jamie presented at http://www.sqlservercentral.com/columnists/jthomson/transactionsinsqlserver2005integrationservices.asp

. My workflow is as followed

*********************************
For Each ADO.Record in Oracle (transaction=not supported)

If (Certain_Field_Value = 'A')


Lookup Data in SQL DB with values from Oracle (transaction=not supported)

DO Sequence A (Start a Transaction , transaction=required)


INSERT/UPDATE some records in SQLDB(transaction=supported)
Finish Sequence A ( transaction should stop here)
UPDATE Oracle DB ( Execute SQLTask, transaction=not supported)
If (Certain_Field_Value = 'B')


Lookup Data in SQL DB with values from Oracle (transaction=not supported)

DO Sequence B (Start a Transaction , transaction = required)


INSERT/UPDATE some records in SQLDB (transaction=supported)
Finish Sequence A ( transaction should stop here)
UPDATE Oracle DB ( Execute SQLTask, transaction=not supported)
If (Certain_Field_Value = 'C')

------------
------------
End ForEach Loop
*************************************
My requirements are that I want separate transaction for each Sequence A, B, C, etc... If Sequence A transaction fails, the other should still be continuing with another transaction.
But I am getting an error regarding the OLEDB Error in next Task (e.g in Certain_Field_Value = 'B') "Lookup Data in SQL DB with values from Oracle ", the error message is ".......Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction. ".
What is it that I am doing wrong?
Regards

BEGIN TRANSACTION COMMIT TRANSACTION Help

Sep 24, 2007

I had thought that if any statement failed within a BEING TRANS .. COMMIT TRANS block, then all the statements would be rolled back. But I am seeing different behavior (SQL Server 2000 8.00.2039)

For instance, run these statements to set up a test:
--DROP TABLE testTable1
--DROP TABLE testTable2
CREATE TABLE testTable1 (f1 varchar(1))
CREATE TABLE testTable2 (f1 varchar(1))
CREATE UNIQUE INDEX idx_tmptmp ON testTable1 (f1)
insert into testTable1(f1) values ('a')

So table testTable1 has a unique index on it..

Now try to run these statements:

--DELETE FROM testTable2
BEGIN TRANSACTION
insert into testTable1(f1) values ('a')
insert into testTable2(f1) values ('a')
COMMIT TRANSACTION

SELECT * FROM testTable2


..the first insert fails on the unique index.. but the second insert succeeds. Shouldn't the second insert roll back? How can I make two operations atomic?

Transaction/statement Not To Log To Transaction Log ?

Sep 20, 2007

Hi There

I have a large database in full recovery model (9.0.3152).

I have s stored procedure, that generates a HUGE transaction log, i have optimized the stored proc as much as i can, i have also broken it up into smaller transactions that i commit more frequently and do transaction log backups more frequently.

However i cannot make a significant dent into the transaction log size.

Is there anyway / syntax to ensure that a transaction or statement is not logged to the transaction log ?

I will never want to have this transaction or commands present if i do a restore.

Is this possible ?

Thanx
