[jira] [Updated] (DRILL-4917) Unable to alias columns from subquery

["Dan Wild (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DRILL-4917?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dan Wild updated DRILL-4917:
----------------------------
    Description: 
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.

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.

  was:

However, when I run the query
`select myVal as myValAlias FROM(select 1 as myVal from (values(1)))`
the alias myValAlias is not applied, and the resulting column is still called myVal.
