Hi
I have the following statement
rows = self.session.query(e.src_id, e.tar_id, \
e.type, m.text, e.event_ts).\
outerjoin(m, e.media_id==m.message_id).\
filter(e.src_id==src_id).\
filter(e.tar_id==tar_id).\
all()[start:offset]
Some of the results are like
(2L, 1L, 3, None, datetime.datetime(2012, 1, 13, 14, 52, 58))
(2L, 1L, 3, None, datetime.datetime(2012, 1, 13, 14, 52, 58))
(2L, 1L, 5, None, datetime.datetime(2012, 1, 13, 14, 52, 59))
event_ts is a Datetime object. Is it possible to convert this to utc
in the statement? I can do this directly with the mysql select
statement, but not sure about if this is possible in sqlalchemy
you'd need to use func.something that does utc(date), let's check mysql's
docs... convert_tz:
http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_convert-tz
so
from sqlalchemy import func
session.query(func.convert_tz(e.event_ts, 'EST', 'UTC'))
