Maryann Xue updated PHOENIX-2579:
---------------------------------
    Attachment: PHOENIX-2579.patch

I see, [~ziyangz]. It would be quite a big effort to provide a complete fix for this problem (plus it would be blocked by PHOENIX-2041), given that Phoenix does derived table expansion on the AST level (we will have logical algebra level optimization with Calcite-Phoenix). I'm attaching a patch that hopefully can work for most of your cases.
