I can't seem to be able to translate the following query into SQLAlchemy.
I would like to translate the following query:
SELECT date_trunc('day', time), "PositionReport".callsign FROM tvh_aircraft."PositionReport" WHERE "PositionReport".reg = 'PH-BVA'
GROUP BY 1, "PositionReport".callsign
I've tried the following, but with no luck.
flight_days = session\
.query(PositionReport)\
.filter(PositionReport.reg == reg) \
.group_by(func.date_trunc('day', PositionReport.time))\
.group_by('1')\
.all()
trunc_date = func.date_trunc('day', PositionReport.time)
flight_days = session.query(trunc_date, PositionReport.callsign) \
.filter(PositionReport.reg == reg) \
.group_by("date_trunc_1")
Thanks in advance for your help.
session.query(func.date_trunc('day', PositionReport.time),
PositionReport.callsign) \
.filter(PositionReport.reg=='PH-BVA') \
.group_by(func.date_trunc('day', PositionReport.time),
PositionReport.callsign).all()
or if you need exactly GROUP BY 1
from sqlalchemy import text
session.query(func.date_trunc('day', PositionReport.time),
PositionReport.callsign) \
.filter(PositionReport.reg=='PH-BVA') \
.group_by(text('1'),
PositionReport.callsign).all()
