             Summary: SELECT COUNT DISTINCT with HAVING fails to plan the query
                 Key: DRILL-1842
                 URL: https://issues.apache.org/jira/browse/DRILL-1842
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 0.6.0
            Reporter: Chris Matta


Tableau is using the following query to get the distinct count of a measure:

{code:SQL}
SELECT COUNT(DISTINCT `custview`.`age`) AS `ctd_age_ok` FROM `mfs.views`.`nestedclickview` `nestedclickview` INNER JOIN `mfs.views`.`custview` `custview` ON (`nestedclickview`.`cust_id` = `custview`.`cust_id`) HAVING (COUNT(1) > 0);
{code}

And it fails on 0.06r2 with a planing error.

Interestingly if I remove the HAVING(COUNT(1)>0) statement at the end it works:

{code}
: jdbc:drill:zk=172.16.1.175:5181,172.16.1.1> SELECT COUNT(DISTINCT `custview`.`age`) AS `ctd_age_ok` FROM `mfs.views`.`nestedclickview` `nestedclickview` INNER JOIN `mfs.views`.`custview` `custview` ON (`nestedclickview`.`cust_id` = `custview`.`cust_id`);

+------------+ 
| ctd_age_ok | 
+------------+ 
| 5          | 
+------------+ 
1 row selected (4.776 seconds)
{code}
