Thanks for the reply, but the solution doesn't work for me.

The problem I posted was actually part of a wider one.  Details:

class A(SQLObject):
        foo = SQLRelatedJoin('B')
        bar = ForeignKey('C')

class B(SQLObject):
        smell = SQLRelatedJoin('B')
        mummy = SQLRelatedJoin('D')

class C(SQLObject):
        fine = ForeignKey('D')

class D(SQLObject):
        hair = SQLMultipleJoin('C')
        bees = SQLRelatedJoin('B')

a = A()

OK, my problem is that I want to find all b = B(), such that a.bar.fine
is in b.mummy AND the intersection of a.foo and b.smell is not an empty
set.

So, I can get b_global = a.bar.fine.bees which gives me a SelectResults
of B instances that contains every one I could be interested in, plus
some more.

I need to select amongst those.  Something along these lines:

for my_foo in a.foo:
        b_subset = b_global.filter(my_foo is in B.smell)

I don't mind having the separate b_subsets at this point, although if I
could aggregate them and specify that each b in b_subsets_aggregate be
unique, then that would be even better.

So, who's got the chops to help me with this monster? :-)
