John Fang updated CALCITE-2323:
-------------------------------
Description:
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.
was:
The configuration parameter "defaultNullCollation" can't take effect for the
query with over, like that:
*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 settting the
> The configuration parameter "defaultNullCollation" which enum NullCollation {
> LOW, HIGH, FIRST, LAST } to allow alternative policies, but it can't take
> effect for over();
