You're not joining anything onto the `rProductCategoryHistory` table, so depending on your DB you may be getting populated rows for rProduct that don't match anything.
you probably want something like this... query = db.session.query(rProduct)\ .join(rProductHistoricalDetails, rProduct.most_recent_historical_details_id==rProductHistoricalDetails.id)\ .join(rProductReviewsHistoricalDetails, rProduct.most_recent_historical_reviews_entry==rProductReviewsHistoricalDetails.id)\ .order_by(rProductHistoricalDetails.time_updated.desc()) unless you missed joining rProductCategoryHistory. you should try writing a raw sql query that gets the right data. -- 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.
