John Fang commented on CALCITE-2323:
------------------------------------
[~julianhyde] can you help me review it again?
> The configuration parameter "defaultNullCollation" which enum NullCollation {
> LOW, HIGH, FIRST, LAST } to allow alternative policies, but it can't take
> effect for over();

> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: John Fang
> Assignee: Julian Hyde
> Priority: Major
>
> For example, the following query:
> *select deptno, rank() over(partition by empno order by deptno) from emp
> order by row_number() over(partition by empno order by deptno.*
> The default null order is nulls last for deptno in calcite. But the null
> order still is nulls last if we set the parameter "defaultNullCollation" with
> NullCollation.LOW.
