Hi, I'm looking for the SQLAlchemy equivalent to the query SELECT * FROM a LEFT OUTER JOIN (b INNER JOIN c ON b.id = c.b_id) ON a.id = b.a_id
Related: https://stackoverflow.com/a/56815807/56974 https://stackoverflow.com/questions/25514160/nested-joins-in-sqlalchemy Table "b" and "c" are joined and filtered first, then the outer join is applied. I was able to achieve the same results using a subquery, whose fields I was subsequently able to load using `contains_eager`. FYI subq = session.query(B).join(C).subquery(with_labels=True) q = (session.query(A) .outerjoin(subq, A.id==subq.c.b_a_id) .options(contains_eager(A.b, alias=subq) .options(contains_eager(B.c, alias=subq)))) r = q.all() I'm curious whether there's an equivalent using the above nested join syntax. Thanks. -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
