             Summary: Window function defined within another window function should be blocked at parsing
                 Key: CALCITE-800
                 URL: https://issues.apache.org/jira/browse/CALCITE-800

          Issue Type: Bug
            Reporter: Sean Hsuan-Yi Chu

For instance,
{code}
select sum(deptno) over (order by 
sum() over(order by deptno)) 
from emp
{code}

This is an invalid query. However, it passes the validation.
