> Currently date datatype is not supported in value based windowing function. 
> For the following query with hiredate to be date type, an exception will be thrown.
> {{select deptno, ename, hiredate, sal, sum(sal) over (partition by deptno order by hiredate
range 90 preceding) from emp;}}
> It's valuable to support such type with number of days as the value difference.
