[jira] [Comment Edited] (DRILL-3238) Cannot Plan Exception is raised when the same window partition is defined in select & window clauses

    [ https://issues.apache.org/jira/browse/DRILL-3238?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14568055#comment-14568055 ]

Interestingly, this case "over W" works:

{code}
select sum(a2) over w, count(*) over(partition by a2 order by a2) from t2 window w as (partition by a2 order by a2);
{code}

I did not realize that over(W) is the supported grammar ...

> {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.
