> While this works:
> {code}
> select sum(a2) over(partition by a2 order by a2), count(*) over(partition by 
> a2 order by a2) 
> from t
> {code}
> , this fails
> {code}
> select sum(a2) over(w), count(*) over(partition by a2 order by a2) 
> from t
> window w as (partition by a2 order by a2)
> {code}
> Notice these two queries are logically the same thing if we plug-in the 
> window definition back into the SELECT-CLAUSE in the 2nd query.
