| 22:52 | Do a more thorough job of cleaning traces of the strength-reduced LEFT JOIN. (check-in: 08833dda3a user: drh tags: join-strength-reduction) | |
| 21:16 | If terms of the WHERE clause require that the right table in a LEFT JOIN not be a null row, then simplify the LEFT JOIN into an ordinary JOIN. (check-in: 5b7abecc7a user: drh tags: join-strength-reduction) | |
