Thanks. That's exactly it. It makes perfect sense why it just happens to work when I join one bar onto this, but not two.
FYI, I'm not seeing a comma on the simple join - but it's still a bad query that illustrates the problem as Bar doesn't get joined in: SELECT foo.id AS foo_id FROM foo JOIN foo2bar ON foo.id = foo2bar.foo_id AND foo2bar.bar_id = bar.id AND bar.is_special = true LIMIT %(param_1)s -- 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.
