> 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}
