-----------------------------------------

             Summary: When Group By clause is present, the argument in window 
function should not refer to any column outside Group By
                 Key: CALCITE-774
                 URL: https://issues.apache.org/jira/browse/CALCITE-774
             Project: Calcite
          Issue Type: Bug
            Reporter: Sean Hsuan-Yi Chu
            Assignee: Sean Hsuan-Yi Chu


An {color:red}invalid{color} query such as:

{code}
select max(empno) over () 
from emp
group by deptno
{code}

This query is invalid because the argument in max (i.e., empno) points at a 
column which is not present in Group By clause. However, Calcite does not catch 
it but generate a plan. 

Invalid queries should fail early to reduce potential confusion.
