Hi all.
I'm trying to switch from SA 0.3 to 0.4. I tested simple SELECT, I've
got a NotSupportedError.
Python: 2.5.1
SQLAlchemy: 0.4 beta6
cx_Oracle: 4.3.2
Environment variable: NLS_LANG=JAPANESE_JAPAN.JA16SJIS
sample code)
-----------------------------------------------------------------
from sqlalchemy import *
from sqlalchemy.orm import *
oracle_engine = create_engine('oracle://scott:[EMAIL PROTECTED]',
convert_unicode=True,
encoding='cp932',
echo=True)
metadata = MetaData(oracle_engine)
Session = scoped_session(sessionmaker(bind=ora_engine,
autoflush=False,
transactional=True))
class Emp(object):
pass
emp = Table('emp', metadata, autoload=True)
Session.mapper(Emp, emp)
if __name__ == '__main__':
smith = Emp.query.filter_by(ename='SMITH').first()
print smith.job, type(smith.job)
-----------------------------------------------------------------
traceback)

'EMP'}
-----------------------------------------------------------------
When I removed convert_unicode=True, this error did not occur. But
type(smith.job) becomes '<str>'. How do I get '<unicode>'?
