Hi Dave! Hi Group!
I used to experience the same troubles with 1:1 relationships, and I am
very happy to say that your fix did it. I was able to export a complex
data structure with 36 tables including several 1:1 relationships from
Access 97 without a problem. Previously the migration used to stop and
roll back when hitting the first foreign key from a 1:1 relationship.
BTW, I agree with the other guy that pleaded for a "per table commit".
Did I see a new option in the migration wizard doing exactly that allready?
Thanx a lot for the tool and especially for the latest fixes. I
appreciate it. Good job!
