This gets the right data: SELECT * FROM r_product_category_history_list JOIN r_product_list on r_product_list.r_id=r_product_category_history_list.r_id JOIN r_product_reviews_historical_details_list ON r_product_list.most_recent_historical_reviews_id=r_product_reviews_historical_details_list.id \G But the problem is I want that data in my rProduct model -- 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.
