In that case, you will need to use "contains_eager" if you play on iterating on any of the relationships http://docs.sqlalchemy.org/en/latest/orm/loading_relationships.html#using-contains-eager-to-load-a-custom-filtered-collection-result you can also write the above with one filter instead of 3: filter(sam.Branch.ckt == ckt, sam.Branch.id_model == case.id, or_(and_(bus1_alias.number == bus1, bus2_alias.number == bus2), and_(bus1_alias.number == bus2, bus2_alias.number == bus1)) ) -- 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.
