Is this fetching to one of these from a completely separate entity,
or fetching to-one from its reflexive relationship? Is this the
same problem that someone else ran into a couple days ago with
relationships from subtypes to the base class of another entity
(guido mentioned something about ERAttachment here that I never saw?).
I have an abstract parent Summary, with three concrete sub types;
HourSummary, DaySummary, MonthSummary. Month has (optional) a to-many
to Day, which in turn has (optional) a to-many to Hour. None of these
should be getting tripped right now and are not prefetched. So, if I
fetch say HourSummary's, I see three sql selects for Hour, Day and
Month. It's almost as if the qualifying attribute is being ignored,
although each sql statement has it in the where clause matching what I
defined in the model in the Basic tab, Qualifier field (see original
post) So one fetch to a specific Entity results in sql selects for all
three, with result sets coming back from all three. Ouch;-) At least
it's fast. Thanks Mike
