That is what I was looking for.

Hello.
Suppose I have the following query:
def people_older_than(age):
q = session.query(Person).order_by(Person.name)
q = q.filter(Person.age age)
return q
It returns a subset of Person instances. How can I augment the query so it
returns only their count? I.e.:
def

Oh, you are right of course. This works, however I would still like to transform
the query programmatically (mainly out of curiosity) from
q = session.query(Person).order_by(Person.name)
q = q.filter(Person.age age)
return q
to
q = session.query(func.count(Person.id))
