Hello,
I have following situation:
1st thread: start transaction, update some values in table (with (rowlock))
2nd thread: starts select for this record.
I have tried some possibilities with SET TRANSACTION ISOLATION LEVEL but noone is suitable for me. I would like during such running transaction to have possibility to read but the OLD values (last commited).
Am I able to reach this behaviour with some setting of locks, transaction level?
Hi,
I am looking for a way to read a transaction log in an Excel format, does anyone know how I can do this? I have already looked at the dbcc log(mydb), and its not documented, doesnt give enough info. I am more looking for an open source/free tool or a way to do it in SQL Server.
Thanks much.
Hi there,
I need to recover certain transactions that I made on the server.
Those transactions were in scripts and I lost the files.
Is there a way to read the transaction log so that I can see what transactions were executed?
TIA
Hi,

How can I read the content of transaction log?
View 2 Replies View RelatedI 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?

View 2 Replies View RelatedHi!
The purpose is to se history of which user updated, inserted or deleted a row in the database.
Can't seem to find any publications from microsoft on how to parse and interpret the log file.
Any documentation on how the log file is structured?
Is it possible to obtain this information through the system views
I don't want to use triggers.
Thanks
our users believe that we lost some valid data, but no one knows who did it,
I thought I can find it from the transaction dumps I take every hour
so ,Can I read Transaction Dumps (*.TRN) file in SQL server 7.0 or Can I get this information through other means.
Thanks for your help

We have poor performance spikes on a drive containing our log file but this is only for reads and seems to be at a time when we run a re-index job. If this is a likely correlation as to poor performance in reading the log file, and what reads are done from a log file.

Hello,
how can i view the content of a archived (backed up) transaction log?
DBCC LOG only works with online logs.
Thx for your answer

I actually am just looking for some supporting documentation on some facets of SQL Server.As far as I have always known, when anyone does a READ from a SQL Server database (SELCT * from <TABLE>), SQL Server does not create a log record...since there's no data or database structure being modified. A colleague is under the impression READ's are logged operations.

I have a local transaction,
BEGIN TRAN
INSERT Z_Test SELECT STATE_CODE FROM View_STATE_CODE
COMMIT
View_STATE_CODE points to remote SQL server named PROD. There is error when I run this query:
Server: Msg 8501, Level 16, State 1, Line 12
MSDTC on server 'PROD' is unavailable.
Server: Msg 7391, Level 16, State 1, Line 12
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d01c].
It looks like remote server is not available inside the local transaction. How to handle that?
Thanks

I am having a very weird problem.
I have the following expression
=Val(Fields!test.Value)
This will display the number if the number is greater than 0.
So it will display any number above 0 and it won€™t display .05
Or .75 any idea?
Thanks

i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?
Can a user of db owner role of a database change the databse option to read only and read-write?If not what permission I need to grant to the user?
