> Need a better error message when we use alias for window definition in query that uses
window functions. for example, OVER(PARTITION BY columns[0] ORDER BY columns[1]) tmp, and
if alias "tmp" is used in the predicate we need a message that says, column "tmp" does not
exist, that is how it is in Postgres 9.3
> Postgres 9.3
> {code}
> postgres=# select count(*) OVER(partition by type order by id) `tmp` from airports where
tmp is not null;
> ERROR:  column "tmp" does not exist
> LINE 1: ...ect count(*) OVER(partition by type order by id) `tmp` from ...
>                                                              ^
> {code}
> Drill 1.0
> {code}
> 0: jdbc:drill:schema=dfs.tmp> select count(*) OVER(partition by columns[2] order by
columns[0]) tmp from `airports.csv` where tmp is not null;
> Error: SYSTEM ERROR: java.lang.IllegalArgumentException: Selected column(s) must have
name 'columns' or must be plain '*'
