> Priority: Minor
>
> I execute:
> {code}
> select platform,
> collect_set(user_auth) as paid_types,
> count(distinct sessionid) as sessions
> from non_hss.session
> where
> event = 'stop' and platform != 'testplatform' and
> not (month = MONTH(current_date()) AND year = YEAR(current_date())
> and day = day(current_date())) and
> (
> (month >= MONTH(add_months(CURRENT_DATE(), -5)) AND year =
> YEAR(add_months(CURRENT_DATE(), -5)))
> OR
> (month <= MONTH(add_months(CURRENT_DATE(), -5)) AND year >
> YEAR(add_months(CURRENT_DATE(), -5)))
> )
> group by platform
> {code}

> operator containing aggregate functions which don't support partial
> aggregation.
