hi friends,

  i did a big mistake.

 in my production database, i had to update one row. normally i had to give one WHERE condition.

But i forgot WHERE condition.

One field in all rows in my table is blank now. Very dangerous maaan.

I am going mad... Please help me...

Rollback transaction is not possible, i guess, since i didnt do any begin trans in the beginning.

if any one knows anything on this, plz send me a reply very fast

Thanx in advance

Why don't you go back to your previous back up?

Yes, you should try to recover the lost values from the last complete database backup. You can restore this backup as a _NEW_ database, and you can copy the data from the restored database to the "real" database.

Here is an example of copying the Employees.LastName data in the Northwind database:

update e
set LastName = eold.LastName
from Northwind.dbo.Employees e
    inner join NorthwindOld.dbo.Employees eold
        on e.EmployeeId = eold.EmployeeId

The second option is to do a point-in-time recovery. This is possible if your last backup doesn't contain the values you accidentally deleted. If the database uses the full recovery model (bulk-logged also?), you can restore the last complete database backup as a new database and then restore the transaction log backup until before the accidental delete. You can recover the values from here.

thanks for the reply guys.. but i dont have a backup for this table.

can i revert the update someways or can i attain the previous stage of table by doing something from the Transaction log?

if so how can it be done...

You can use a tool like Lumigent Log Explorer (www.lumigent.com) to browse through the log file. I never used it.

or maybe you can try the following: create a new database and back-it up. Then restore it WITH NORECOVERY and then try to do a point-in-time restore using the transaction log backup, from the production database, to a point before the acident. the chances for this to work are slim, but maybe it will. i don't have time to test this myself.
