> Key: DRILL-4917
> URL: https://issues.apache.org/jira/browse/DRILL-4917
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.8.0
> Reporter: Dan Wild
>
> Column aliasing works in a simple query (without subqueries):
> {code}
> select 1 as myVal from (values(1))
> {code}
> My result set gives me one column called myVal as expected
> |myVal||
> |1|
> However, when I run the query
> {code}
> select myVal as myValAlias FROM(select 1 as myVal from (values(1)))
> {code}
> the alias myValAlias is not applied, and the resulting column is still called
> myVal
> |myVal||
> |1|
> This is problematic because if my query instead looked like
> {code}
> select myVal, SUM(myVal) as mySum FROM(select 1 as myVal from (values(1)))
> GROUP BY myVal
> {code}
> I would get a result set back that looks like this, with no way to alias the
> second column:
> |myVal|$f1|
> |1|1|
