> Column aliasing works in a simple query (without subqueries):

> 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}
> 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|

Hugo Bellomusto commented on DRILL-4917:
Same behavior with group by and *sum* function:
{code:sql}
SELECT EXPR$0 col1, sum(EXPR$0) ignoredAlias
FROM (VALUES(1))
GROUP BY EXPR$0
{code}
||col1||{color:red}$f1{color}|
|1|1|
Using count, avg, min, max it works well.
