如何在Python中加入2个查询

Question

I am in Python and I have the above 2 queries which I want to join them in 1.

def fly_away(session, line_id):
    query = session.\
              query(
                Pilot.Id,
                Pilot.EntityId,
                Pilot.From
              ).\
    filter(Pilot.Id == line_id)

    query = session.\
                  query(
                    CTower.Id,
                    CTower.Time,
                    CTower.Associate
                  ).\
    filter(CTower.Associate == line_id)

I tried to use join but I dont know how to use it correctly. Can I have some help please?

Answer 1

I don't know what database are you using and what driver are you using to connect python to the database but I will post the sql query that will do the job. I am sure, you can use it with your driver.

SELECT Pilot.Id, Pilot.EntityId, Pilot.From, CTower.Id, CTower.Time, CTower.Associate 
FROM Pilot, CTower 
WHERE CTower.Associate == Pilot.Id

Answer 2

def fly_away(session, line_id):
  query = session.\
          query(
            Pilot.Id,
            Pilot.EntityId,
            Pilot.From,
          ).\
          outerjoin(CTower, Pilot.Id == CTower.Associate).\
          filter(Pilot.Id == line_id)     
  return query

this is what I am trying now.. and its working .. but not exactly as I want
