| 16:34 | Add test cases for the query flattener fix for ticket [2f7170d73bf9abf8]. (Closed-Leaf check-in: dd8f7f75 user: drh tags: tkt-2f7170d7) | |
| 16:09 | Propagate the COLLATE operator upward through function calls. Initial fix for ticket [ca0d20b6cdddec5e8]. (check-in: c053448a user: drh tags: tkt-2f7170d7) | |
| 15:21 | Disable the query flattener for aggregate subqueries if the parent query uses other subqueries in its result set or WHERE clause or ORDER BY clause. Preliminary fix for ticket [2f7170d73bf9abf8]. However it still contains a defect similar to the COLLATE problem of [ca0d20b6cddd]. (check-in: 0b7d65e3 user: drh tags: tkt-2f7170d7) | |
