This seems to facilitate a much more flexible style of building

It would be nice to make the select() also using this style.
so building selects can be
s = select([users])
if order_by_address:
s.order_by(addresstable.c.address)
else:
s.order_by(user.c.id)
s.limit(5)
curs = s.execute()
when you use the SelectResults extension, the select() method also has
the same behavior (except for the execute part).
Do we really want to use that slicing [] syntax though ? I tend to
switch to SQL mode when writing queries in SA, so SQL keyword functions
like order_by, limit(limit, offset=None), having(), for_update() etc.
would make much more sense. Using specific python syntax for this
single case just feels inconsistent.
well the extension is totally based on the similar functionality in
SQLObject and i think the LIMIT/OFFSET part of it is something people
look for as well. But you can mix and match both styles using
select(), in fact. how un-pythonic (as usual).
I actually hate that word "pythonic". It's one of those words people use
for so many different reasons without consistency. I like having many
ways of doing things, because it provides convenience, matches different
trains of thought, different uses cases etc.. As long as there is
consistency, and people can intuitively guess on how something should
work, I think this is ideal. So it's okay that select(order_by=None,
limt=None).order_by().limit() exist, as long as it also exists on
select_by and what ever other query statement that are applicable.
Just MO so feel free to ignore.
i never ignore anything ! (intentionally)
Always a good attitude.....I try but there is so much garbage on the web.
