> For example,
> {code}
> select empno, sum(empno) over (w), count(*) over w
> from emp
> window w as (partition by empno order by empno)
> {code}
> Notice that the second select item has parenthesis in the window clause. This query would generate a wrong plan:
> {code}
> LogicalProject(EMPNO=[$0], $1=[$9], $2=[$10])
>   LogicalWindow(window#0=[window(partition {} order by [0] range between UNBOUNDED PRECEDING and CURRENT ROW aggs [SUM($0)])], window#1=[window(partition {0} order by [0] range between UNBOUNDED PRECEDING and CURRENT ROW aggs [COUNT()])])
>     LogicalTableScan(table=[[CATALOG, SALES, EMP]])
> {code}
> where we have two windows in the LogicalWindow.
