Recovery from Delete statement using the transaction logs

I ran some delete statements in Query Analyzer and I
found out it was the wrong database. Can you rollback the
delete statements and recover the data from the
transaction logs?
I assume you didn't protect the delete with BEGIN TRAN? If you did, just do ROLLBACK.
Are you performing regular transaction log backups? Is database in full or bulk logged recovery
mode? If answers to these questions are "no", you will probably need to go to your most recent
backup or just accept the data loss. If answers are "yes", you *might* be in better shape.
Anyhow, I suggest you read my article on the topic at:

You'll have to use a log reader tool from Lumigent or LogPi. Otherwise,
you need to restore from a backup. If the table is static, you may be
able to restore the database to another (test) server and use DTS to
copy the table.
Some backup/recovery tools like our LiteSpeed product offer object level
recovery.

data.
Too late now but it's a good idea to bracket your ad-hoc DML statements
with BEGIN TRAN ... ROLLBACK TRAN until you are sure that the
modification is correct. Also a good idea to have a current backup of
course :-)

Hi Robert,
You can't rollback after committing the transaction.
Besides the options posted by David and David, the might be one more
option for you: If your database is in full recovery mode, you can use
point in time recovery to restore yoour database to the point in time just
before you ran the unintended deletes. This will of course destroy ALL
modifications since that time, so it may or may not be usefull.
Best, Hugo

Recover the data

Hi,
My appln runs on a remote server. A few minutes ago i accidently ran a
'Truncate table' command. Is there anyway to recover it thru Query Analyzer.
The DB Recovery model is SIMPLE and i have the dbOwner permission.
Thanking in Advance
LaraNo. Restore from the latest database backup or re-load the data. You can try
any of the log reading
tools (I've listed some on my links page), but the data is most probably not
in the log anymore
because of simple recovery mode.
