Hi,

I have a fact table with two measure columns one is cnt and other is val
with count & sum measures defined over both columns. Val has either median
or average for that day.
Now if I want to calculate mean & median for a month I would be required to
do the following, sum(cnt * val) / sum(cnt).
I run the following query select sum(cnt * val) / sum(cnt) from test_table
where data_type=23 and event_date between '2016-04-01' AND '2016-04-30';
I get a NullPointerException. Complete error attached to the mail.
I am guessing this is probably due it not being able to find a realization
that matches the sum(cnt * val) measure. If not is there something else I
am doing wrong ?
Usually when you try to query with a aggregation that is not a part of the
cube the error is that it can't find any realizations. But this query just
returns null.

Are there any plans to support these kind of aggregates ?

Thanks,
-Joel
