Hongze Zhang updated CALCITE-883:
---------------------------------
Comment: was deleted
(was: {quote}with my understanding the first operand of RexOver may become a
"NULL TREATMENT" operator rather than an aggregate operator causing some "if
...else..." and it seems ugly{quote}
If you want to make the SqlNode of null treatment optional, I think the call
should be the last operand but not the first one.)
> Support RESPECT NULLS, IGNORE NULLS option for LEAD, LAG, FIRST_VALUE,
> LAST_VALUE window functions
