Alicia Ying Shu commented on PHOENIX-1580:
------------------------------------------
[~jamestaylor] Appreciate your review. I am at the same boat.
1. I used a way to explain plan before which gave correct results. I was asked
to changed to use different method. The extra steps came from existing explain
plans afterwards. I can fix it as you said.
2. I already said without checking NULL, tests failed with NPE.
3. I got confused about Maryann's comments about SQLUnsupportedException. I can
definitely put those back.
