Lemont created KYLIN-3405:
Summary: kylin mandatory dimension
Issue Type: Bug
I created a simple cube on kylin 2.3.1，the table has three
dimensions:pt,biz_time and periods_time ，one measure
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)
from rider_view where pt = '20180530' and periods_time in(0) and biz_time
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.
