Hi, I'm having some trouble with sqlalchemy and timestamps I have a schema which looks like this
class MyTable(Entity): __tablename__ = "MyTable" id = Column(Integer, primary_key=True) tstamp = Column(DateTime, nullable=False) when I run a query such as current_time = datetime.datetime.utcnow() s = current_time - datetime.timedelta(hours=1) hour_ago = s.isoformat() query = session.query(func.count(MyTable)).filter(MyTable > hour_ago) I will get the following StatementError - but not on my local testing (mac os sierra) system, only when testing the system on our live docker based system (Ubuntu:wily) Has anyone come across this issue before? I've tried using a date time object but that resulted to the same problem so I opted to change to the iso string. It seems that the timestamp is simply not being passed to the query statement in the parameters. StatementError: (sqlalchemy.exc.InvalidRequestError) Can't reconnect until invalid transaction is rolled back [SQL: u'SELECT count(`MyTable`.id) AS count_1 \nFROM `MyTable` \nWHERE `MyTable`.tstamp > %s'] [parameters: [ {} ]] Any help would be much appreciated.
