> 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.
