Yes, those are called subqueries; they're fully supported by SA. Your
query above has a couple of items of note:
a) it's a correlated subquery: the inner query references items in the
outer query. (supported by SA)
b) it's a self-join: the inner query and outer query reference the same
table. (also supported by SA)
your query roughly translates into:
p2 = p.alias()
select([p.c.id ], p.c.number == select(func.max(p2.c.number),
p2.c.attribute == p.attribute))
