> URL: https://issues.apache.org/jira/browse/KYLIN-3405
> Project: Kylin
> Issue Type: Bug
> Reporter: Lemont
> Priority: Major
>
> I created a simple cube on kylin 2.3.1，the table has three
> dimensions:pt,biz_time and periods_time ，one measure
> :online_rider
> Something trouble me is that when i set biz_time to the mandatory
> dimension,the sql will execute fail.
> The sql is :
> select floor((1524931200 - biz_time)/(30*86400)), count(DISTINCT
> online_rider) onlineRiders
> from rider_view where pt = '20180530' and periods_time in(0) and biz_time
> >1524931200
> group by floor((1524931200 - biz_time)*1.0/(30*86400)) .
> The error is :
> null while executing sql.
> But when I remove the condition of periods_time in(0) or floor function the
> sql will execute success.
> I don't know what's the relationship between the two.
