Forgot to say a few things :

Yes, Gail, data is critical.

Yes, we've been over it with the customer telling him to pay more attention the next time.

I also think the solution you just gave me is the only one : Rebuilding it all from scratch...

Problem is, I'm too much of a newbie to perform that. For instance : I don't really understand when you tell me to "script things".

So, bottomline, I was trying for some "miracle solution" to get me through, but this solution, of course, doesn't exist at all...

Do you know some link where I can see that "script objects / bulkcopy data" trick, thoroughly explained, so I don't make things worse.

A colleague of mine (Better DBA than me, but no longer here) already tried something of the kind, with a backup DB, but things didn't work out because (quoting) "some SP were encrypted". Rings a bell ?
