i'm using sqlalchemy on mysql database. there way can use mysql's using clause join tables?

e.g.

select *   join b     using(some_id, other_id); 

short answer

no.

longer answer

you write compiler extension render statement, don't think worth effort. explanation below.

in mysql don't have use using join tables. it's considered syntactic sugar on more general on construct.

sqlalchemy not include handling special case join columns have same name (main use-case using using). uses general approach (on).

as sqlalchemy render on statements you, , in cases infer join-relationships table definitions , obviating need specify join condition at all, not more work.

example

t1 = table('a', metadata,            column('id', integer)) t2 = table('b', metadata,            column('id', integer),            column('fk', integer, foreignkey('a.id')))  sel = select([     t1.c.id,     t2.c.id, ]).select_from(     t1.join(t2)  # please note, no on or using ) print sel 

will result in

select a.id, b.id  join b on a.id = b.fk
