>            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.
