Subject [jira] [Created] (DRILL-5467) Issue with column alias
Date Wed, 03 May 2017 13:28:04 GMT
Rakesh created DRILL-5467:

             Summary: Issue with column alias
                 Key: DRILL-5467
                 URL: https://issues.apache.org/jira/browse/DRILL-5467
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.10.0
            Reporter: Rakesh

The column alias is not always correctly used in output. When columns as calculated in nested
table, the outer most project doesn't show the column alias correctly:

SELECT `Custom_SQL_Query`.`Bucket` AS `Bucket`,
  SUM(`Custom_SQL_Query`.`male`) AS `sum_male`
FROM (SELECT first_name as `Bucket`, salary as `num`, case when gender = 'M' then 1 else 0
end as male, case when gender = 'F' then 1 else 0 end as female FROM cp.`employee.json`) `Custom_SQL_Query`
GROUP BY `Custom_SQL_Query`.`Bucket`

Here 'sum_male' appears as $f1 instead
