I don’t have direct answer to your question, but I’ve frequently found it helpful to write these kind of comparisons in SQL rather than trying to understand what 4D may be thinking internally. It’s easier to be explicit in SQL, at least in my experience. I’m not good enough at SQL to write something off the top of my head, especially when I don’t have the data to test it on. Sorry this isn’t much help.
