Hi Jeff,
I uploaded the relevant DDLs. I don't think that the third one is important, as it happens with almost any table that I add. Playing around with it in order to send you a simple screenshot, I found a workaround. If I delete the IS_ISUK_BEFOAL table from the querey builder and bring it back, the weird behavior stops.
I have dificulty removing a specific relation from the query builder. Is there an easy way for Toad to add a "Remove" button to the properties window of the relationships of a query builder? This way I can specify which relation should stay and which one should be deleted.
Sincerely,
Shimon J.
