the easiest way to do this would be to issue the SQL yourself...below
uses the object_session() and object_mapper() functions to ensure that
the current connection, if any, is used (you could also just say
myengine.execute() if that didnt matter):
class MyClass(object):
@property
def someprop(self):
return object_session(self).\
execute(select([MyClass.somecol]).where(MyClass.id==self.id),
\
mapper=object_mapper(self)).scalar()
