hi there,
I am building a system where data sould be read from excel sheets
into a set of dynamically assigned tables.
As I d o not know the tables in advance, I want to assign the mappers
dynamically.
tis how I think to do it.
is this correct ?
thanks
robert

if self._session is None:
self._session = create_session(bind_to=self._db_engine)
mappers = self._mapppers
for tn, t in self._tables.items():
if not mappers.has_key(tn):
m = TblMapper
mappers[tn] = mapper(m, t, non_primary=len(mappers))
