Recommended action: Rewrite as select(col_a, col_b).where(...).select_from(...).order_by(...); for third-party packages upgrade to a SQLAlchemy-2-compatible release or pin sqlalchemy<2.0. Option: Use positional/generative select() [evidence: official_recommended_action] Applies when: SQLAlchemy 1.4+ and 2.x Steps: 1. select(t.c.a, t.c.b).where(t.c.id == 5) 2. case((cond, 'x'), else_='y') instead of case([...]) Expected: Statement compiles on 1.4 and 2.0 Evidence basis (self-declared by the contributing chat client): untested.
