I know this is an old thread, but there isn't much on the web around
generate_series and SQLA, so I thought I might revive it.
One of the suggestion was to use:
s = func.generate_series(4,5,6).alias(cols=['a'])
select([func.current_date() + s.c.a])
Unfortunately, alias doesn't take a `cols` ar
OK r4566 of trunk also allows text() within select_from(), so you can
use textual bind params (denoted by a colon ':'):
generate_series = text("generate_series(:x, :y, :z) as s(a)")
s = select([(func.current_date() +
literal_column("s.a")).label("dates")]).select_from(generate_series)
