restore with dev database and transaction log.

Problem:
A database has been deleted. I have a development version, which dates from
some time in the past. (8/23/03). I have transactions logs dataing from
2/15/04. This is not a heavily used system and some data will be better
than anything. However, when I try to apply the first transaction log, the
system tells me, not surprisingly, that this is not a valid log for this
database.
Assistance Requested:
Is there some way to "fool" SQL server into thinking that the transaction
log should apply? Are their date/time stamps recorded in a system table that
I could overwrite? Even if some data is corrupted, something is better than
nothing.
Moral of the story:
Do not believe you operations people when they tell you that tape backups
are working. VERIFY. Force them to do regular tests. (the backup files on
the tape are either missing, or are 16 KB a piece)

Hi John,
As my understanding of your problem, you have delete one of you database on
the production SQL server, then you only have the database on the develope
server. You also have a 'transactions log dating from 2/15/04', you want to
recover the database, right? If I misunderstood you, please feel free to
let me know.
For your 'transactional log dating from 2/15/04', I assume it is a
transaction log backup. However, based on my knowledge, it is not possible
to apply a transaction log backup:
1) Unless the database or differential database backup preceding the
transaction log backup is restored first.
2) Unless all preceding transaction logs created since the database or
differential database were backed up are applied first.
3) If the database has already recovered and all outstanding transactions
have either been rolled back or rolled forward.
You cannot restore the transaction log backup on an old database.
Thanks. For any question, please feel free to post message here and we are
glad to help. Thanks
Best regards

|||You have understood the problem correctly. I was hoping to be able to change
the timestamp or in some other way trick SQL server into accepting those
logs. However, your message confirms for me that the database is
unrecoverable. Oh, well -- NMF (not my fault)
Thanks
