OK, not really, you want tables in the FROM clause. use either the
select_from() or join_from() method to do that:

Here’s the select, and most of the from clause:

from tb_v as v,
tb_nv as nv,
tb_bs as bs,
tb_br as br,

it’s probably too much detail to share. It’s 43 lines of SQL with multiple

Would just the simplest parts of the from clause work?

That makes sense, but…. I’m afraid I don’t know how to add tb_br to the select.
I tried:
query = (
select(NV.id, func.min(bs_3.build_id))
.select_from(bs, Br)
.join(v_2, onclause=(bs.version_id == v_2.id))
.join(bs_2, onclause=(Br.id == bs_2.branch_id))
)
