Restore of DB

We had a DB A. The person reinstalled SQL, and A now isn't recognized. The
y never did a backup. The MDF and LDF Files still exist. Is there a way to
recreate the DB, and have it look at the old LDF and MDF files, or is there
a way to recreate the DB,
and copy the information from the old Files over?
I think I saw a similar question to this before, but I don't know if it will
apply to me. As it referenced to DBs that exist, and mine is about one tha
t used to exist, but somehow went away.
DaniCheck out sp_attach_db.

I think the .ldf and .mdf files would be on a different
drive ( for example on drive D )when SQL Server was up and
running, and as usual the guy would have formatted Drive
C coz of some issues and Installed the SQL Server again.
Does sp_attach_db suceed, as the database is not detached?

It should work, as long as you've got the mdf file you can use the
sp_attach_db, just specify the new file location.
Steve|||I thought sp_detach_db took some data out of master and attached it to the
mdb. I didn't think attach would work without detach.

sp_attach_single_file_db and passing only the mdf file location, the ldf
file will be auto created and you should be fine. committed transacions that
were not physically written to disk(in controller cache) will be lost
obviously depends on yor cache settings

This is interesting as I use to think that only cleanly
detached databases can be attached.
Thanks for all your views

doesn't. We have tons of messages here from users who assumes that attach
would work without a prior detach. Books Online states that attach work *if*
you detached first, so consider the rest a lucky bonus. And for re-creating
the log file, it will only work if the db had only one db and one log file
and it didn't have any recovery work to do (in most cases, it was indeed
properly detached first).
