no, the identity mapping is based on the class + primary key, so as long as the
primary key consists of the same columns (i don’
Would I be correct in assuming this Version object won't be in the same
identity map as the other Version objects?

This is pretty amazing. I get it to *almost* work. The issue seems to be
that I don't use the database column names as my model attribute names. The
db column names are really obfuscated, so it's more like:
class Version(Base):
id = Column('vrsn_nbr', Integer, primary_key=True)
date = Colu
well I can get it to work for lazy loading like this:
expr = select([func.max(Version.id)]).\
where(Version.object_id == Object.id).\
correlate_except(Version).as_scalar()
Object.current_version = relationship(Version,
primaryjoin=and_(
