What you are seeing is peculiar. We regularly run the whole foodmart-based
test suite against derby, and it works fine.
Mondrian knows that Derby supports 'count(distinct ...)' so the "while
counting members of level" queries are of the form 'select count(distinct x)
from ...' rather than 'select count(*) from (select distinct ...)' that you
I'd like to get to the bottom of this issue. What version of derby, mondrian
and java are you using?
