As theres a lot of clamor for this lately, FYI to those looking for a
more flexible "select_by". the SelectResults extension can give you
a lot of what youre looking for.
from sqlalchemy.ext.selectresults import SelectResultsExt
addressmapper = mapper(Address, addresstable)
usermapper = mapper(User, usertable, properties=
{'addresses':addressmapper}, ext=SelectResultsExt())
result = usermapper.select_by(address='[EMAIL PROTECTED]').order_by
(addresstable.c.address)[4:15]
will add "LIMIT 4 OFFSET 15 ORDER BY addresses.address" to the
generated query before executing.
