Well, I think that's going to make your job difficult then. Obviously
whatever is happening, the insert code is doing more than expected.
Remember, a view is the result of a query, it's not hard to create
views where you can't do meaningful DELETE rules. In your example
you're joining many tables. If any of those tables have a duplicate
value, that would duplicate records in the result. You can't delete any
particular duplicate because it is the result, not the cause.
Hope this helps,
