Would it make sense to add a __nonzero__ method to ResultProxy that
was tied to the rowcount?
def __nonzero__(self):
return bool(self.rowcount)
This would allow code like
if results:
process(results)
I was surprised when this did not work.

Hello all,
I feel I am seriously missing some point here.
suppose I am creating a class representing a table through orm.
I will asume that it is using declarative syntax.
I wish to know how do we index a field?
that is to say, I need to have indexes on a few fields so that they are
applied to
What is the SA equivalent of:
UPDATE foo SET bar=some_function(baz) WHERE bar IS DISTINCT FROM
some_function(baz)
I get this far (assuming 't' is a Table instance):
t.update().values(t.c.bar=sa.func.some_function(t.c.baz).where( ...
what do I put here )

In the right places, it's mighty useful.

There are two tables pump and curve. The curve table has three fields,
curve_pn, head and gpm. The design is that the rows with the same curve_pn
value represent x,y points (head,gpm) on a pump performance curve. Each row in
the pump table has a curve_pn column that links to the performance
