[jira] [Created] (KYLIN-3405) kylin mandatory dimension
Lemont created KYLIN-3405:
-----------------------------
Summary: kylin mandatory dimension
Key: KYLIN-3405
URL: https://issues.apache.org/jira/browse/KYLIN-3405
Project: Kylin
Issue Type: Bug
Reporter: Lemont
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.
