Thanks!
Here is a slightly modified version that shows what happens : if querying
in another session, with a from_statement, the string is not processed. Is
it the expected behaviour ?
from datetime import datetime
from sqlalchemy import Column, DateTime, Integer, create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
engine = create_engine('sqlite://', echo=True)
Base = declarative_base(engine)
Session = sessionmaker()
class LogEntry(Base):
Log class
__tablename__ = 'log'
#common data
id = Column(Integer, primary_key=True)
timestamp = Column(DateTime)
def __init__(self,timestamp):
self.timestamp = timestamp
log = LogEntry(timestamp=datetime.now())
Base.metadata.create_all()
session = Session()
session.add(log)
session.commit()
session.close()
session = Session()
log_1 = session.query(LogEntry).one()
session.close()
session = Session()
log_2 = session.query(LogEntry).from_statement(select * from log).one()
session.close()
print type(log_1.timestamp)
print type(log_2.timestamp)

Hi all,
I'm using Python 2.6.5 and SQLAlchemy-0.7.8 over sqlite3 to store and
retrieve logs with in table like this :
class LogEntry(Base):
Log class
__tablename__ = 'log'
#common data
id = Column(Integer, primary_key=True)
timestamp = Column(DateTime())
When querying back object, how comes I get unicode string in timestamp
attribute ? Isn't SA supposed to convert ISO formatted string stored in
sqlite back to python datetime object ?
