Using Transaction Log To Update Another Database
Jul 20, 2005
I am doing some replication setup in test environment. Will it be possible
to use the transaction log from a production server to update the test
server? Any reference to any document will also be appreciated.
I know I have to restore most recent backup from the production server to
the test server. and all the transactions after the backup on the production
server has to be run on the test server.
Thanks for your reply.

SQL Server 2000, C#, ASP.NET and ADO.NET. I have searched for 3 days trying to figure out why my ADO.NET Transaction executes my stored procedures and runs the .COMMIT() on the server, figured this out by using the SQL Profiler, but the data doesn't show up in the database tables and I recieve no error from SQL or ASP.NET. What gives???? Anyone else ever heard of such a thing. Please help, before I loose my sanity.

I have a simple update:
begin transaction
update table1
set column1 = 10
where column2 = 'ABC'
If @@Error > 0 then
rollback transaction
else
commit transaction
print 'show all updated fields'
go
What i want to achieve is if transaction is successful, i would like to see which fields were updated (in form of report or something like following below:
column0 | column1 | column2
---------------------------
1 | 10 | ABC
21 | 10 | ABC
12 | 10 | ABC
251 | 10 | ABC
4 row(s) updated.
There should be a clause like OUTPUT, but don't know how to use it :-(
thank you

I have an application which uses DTS to import data. After the data is imported the transaction logs are no good since the import wasn't logging.
Is there a way to turn logging on?
Thanks

Hi,
Good morning to all. I'm facing the following problem. Can anyone please help me!...When a transaction is open, the database is getting locked for other user to fetch the records from database.I have to update multiple database table with huge data (Lac). So the transaction will be open for longer period. Mean while if somebody tries to fetch or do select query it give timeout exception. And it does not function until the transaction is closed.How to avoid this database locking for other users. Below is the code that i have used: using (DbConnection dbconn = base.db.CreateConnection()) { dbconn.Open(); DbTransaction dbtran = dbconn.BeginTransaction(); try { Here inserting, updating to multiple table will be happening
dbtran.Commit(); } catch (SqlException ex) { dbtran.Rollback(); } finally { dbconn.Close(); } }
Thanks in advance... :)
Regards,Ashok kumar.

Hi All,
I want to know that how we will be able to update multiple rows in single transaction.
e.g If original database is
S_No Data
1 -
2 -
3 -
4 -
After
S_No Data
1 1
2 3
3 6
4 10

I have looked at the membership and roles stored procs from Microsoft and noticed that most of them are wrapped into a transaction. Ok some of the stored procs updated more than one table in which case it makes sense to wrap the code into a transaction. Our stored procs are a little simpler and insert, update or delete only one table for the most part. My question is: What is good practice, should I wrap my stored procs in transactions or because I am only updating one table leave it the way it is, see sample below: Please advise, newbie
ALTER PROCEDURE [dbo].[syl_Category_Insert] @CategoryName nvarchar(64), @LanguageID int
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
BEGIN TRYINSERT INTO [syl_Categories]
VALUES(
@CategoryName,
@LanguageID)
SELECT SCOPE_IDENTITY() AS [CategoryID]
RETURNEND TRY
BEGIN CATCH
--Execute LogError_Insert SP EXECUTE [dbo].[syl_LogError_Insert];
--Being in a Catch Block indicates failure.
--Force RETURN to -1 for consistency (other return values are generated, such as -6).RETURN -1
END CATCH
END

I am running a vba procedure ( adp file ) that executes successively 5 stored procedures . however it happens that the execution breaks at the middle of the code thus giving a situation where only 2 tables among 5 are updated.
Is it any solution to rollback transactions update already done before
the code breaks due to error ?
I was thinking about combining all stored proc on a big one and use
Begin transaction - commit transaction and rollback transaction ... however i am not sure wheter updates involving several tables can be handled on one transaction.
Any advise highly appreciated !

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
update TSADMIN.TRANSACTIONMAIN
set REPFLAG = 0 where REPFLAG = 1 and DONE = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.WBENTRY
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.WBENTRY
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.FIXED
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.FIXED
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.ALTCHARGE
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.ALTCHARGE
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.TSAUDIT
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.TSAUDIT
set REPFLAG = 0 where REPFLAG = 1
COMMIT TRAN
It's got me stumped, so any ideas gratefully received.Thx

We have a rather large environment and have just a couple of boxes out there that we are getting cannot begin distributed transaction on inserts and updates but works fine on selects. Inserts and updates work fine outside the begin tran / commit so it's definitely DTC
We have checked the configuration on and the source box is set to No authentication required same for destination.
We have: Verified credentials running the service, changed them, same problem. Uninstalled and re-installed MSDTC per Microsoft instructions.
Have run all the tools for checking DTC DTCPing etc and followed those procedures which typically in the past has resolved any DTC issues. Other than swapping out the offending pc for a new one we are at a loss.

I have a design a SSIS Package for ETL Process. In my package i have to read the data from the tables and then insert into the another table of same structure.
for reading the data i have write the Dynamic TSQL based on some condition and based on that it is using 25 different function to populate the data into different 25 column. Tsql returning correct data and is working fine in Enterprise manager. But in my SSIS package it show me time out ERROR.
I have increase and decrease the time to catch the error but it is still there i have tried to set 0 for commandout Properties.
if i'm using the 0 for commandtime out then i'm getting the Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
and

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

We have a SQL database that uses Active Directory with Windows Authentication. Can users that are members of the Active Directory group that has read/write access to the SQL database create ODBC connections to access the database directly and update the data? They dont have individual logins on the server. They are only members of the Active Directory group that has a login?

I had to to relocate the database log file and I issued an Alter database command but by mistake I put a space in the file name as below. The space is at the beginning file name. Now I am unable get the database loaded to SQL Server. The database has 2 replications configured, so deleting and re-attaching the database means the replication needs to be re-configured. Is there an alternative way to issue a command to update the database FILENAME ? Not sure if this can be edited in master database (sys files).
ALTER DATABASE [User_DB]
MODIFY FILE (NAME = User_DB_log, FILENAME = 'I:SQLLogs User_DB_log.ldf')

I still have transactions in use mainly to set isolation levels. There are obviously no update/delete statements in them. I'm pretty sure this will still add rows to the transaction log even though there won't be any writes to the db data files. Is it still a critical best practice to use RAID 1/0 instead of RAID 5 for the logs? Looking to re-use some existing storage rather than buy new ones. Thoughts?

Hi!
I have an original database that I want to copy once to another database. Then I want to update the data weekly with the data of the original database. I don€™t change any tables or columns in that part of the database. Just some tables more in the €˜new€™ database (than the tables from the original database) with some references to the tables that have to be updated weekly.
How can I do this? (if you know what I mean... it's a sort of a datawarehouse where different sources come together.. that part that represents the original database is just a part of the datawarehouse. That part is exactly the same structure as the original database.)
Thanks,
Sandra
