--------------------------------------

             Summary: Count() function is not working with columns alias
                 Key: DRILL-6995
                 URL: https://issues.apache.org/jira/browse/DRILL-6995
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.15.0
            Reporter: Denys Ordynskiy


The query works correctly if I use column name in the count() function:

{code:java}
select department_id c from cp.`employee.json` group by c having count(department_id) > 1
{code}
|c|
|1|
|2|
|3|
|11|
|5|
|4|
|19|
|14|
|15|
|16|

But when I set column alias "c" in the count() function, Drill returns *an empty result set*:
{code:java}
select department_id c from cp.`employee.json` group by c having count(c) > 1
{code}
|c|
| |
