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.
Regards,
K,
