|Subject||Re: [firebird-support] Error creating Foreign key|
1. Why do you remove all FK?
2. Why do you still use such old Firebird version?
Many things was fixed since FB1.5 and i suppose that only real fix to your problem is using recent FB.
You can try disconnect after every FK.
You can also try do select count(*) from updated tables but you say that you do backup and restore...
