| 16:28 | When estimating the number of rows visited by a range scan for which the keys consist of more than one field, consider prefixes of stat4 samples as well as the full samples. This generates more accurate estimates. check-in: 3e0590de user: dan tags: trunk | |

| 20:10 | Prevent partial indexes on the table on the left hand side of a LEFT JOIN from being incorrectly qualified by a constraint in the ON clause of the join.

| 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 | |
