Got it, thanks! One last question if you have the time:
for some reason it's looking at the wrong schema when parsing my UDF
func.non_conflict_middlename in the update statement, despite parsing fine
in the base query and subquery. I suspect that this is because my first
table in the update

it's a Core selectable so you need to use the .c. prefix -
alias.c.columnname

Thank you so much for the reply! I'm almost there but am having trouble
selecting the abms_biog.id column from my subquery - I'm getting an
"AttributeError: 'Alias' object has no attribute 'abms_biog'" when I try:
u = update(abms_biog)
u = u.prefix_with("ignore", dialect="mysql")
build an update out of abms_biog:
stmt = update(abms_biog)
use prefixes to get the "ignore" part:
stmt = stmt.prefix_with("ignore", dialect="mysql")
make sure your subquery is a Core selectable:
subq = my_orm_query.subquery()
add your subquery to the WHERE clause. e.g. the JOIN keyword
I'm trying to recreate the following SQL in SQLAlchemy:
update ignore abms_biog a join
(select a.id, u.id as user_id from abms_biog a
join 3md.users u on u.firstname = a.firstname
and u.lastname = a.lastname
and 3md.non_conflict_middlename(u.middlename, a.middlename)=1
and u.credentials in
