Hi,
I got some query like this:
sites = db.session.query(model.Site, func.sum
(model.ProxyOnAir.listeners).label('listeners')).\
join(model.OnAir).\
outerjoin(model.ProxyOnAir).\
group_by(model.Site.user_id).\
order_by('listeners')
The only column I needed is Site, but however, I also need the sum of
listeners to sort sites. The result will be
[
(Site, listeners),
(Site, listeners),
(Site, listeners),
...
]
I know I can handle it like this:
map(lambda x: x[0], result)
But if I do that, I can't use result[:limit] which imply LIMIT syntax.
So my question is, how can I exclude some columns that I don't need? I
want the result be a list like this [Site, Site, Site, ...]
Thanks.
Victor Lin.
