| ||
| 02:52 | [3bf8006d44] part of check-in [309bbedf96] Fix the query planner so that when it has a choice of full-scan tables to move to the outer loop, it chooses the one that is likely to give the fewest output rows. Ticket [13f033c865f878]. (check-in: [309bbedf96] user: drh branch: trunk, size: 8054) | |

| 19:14 | [97d3936e6a] part of check-in [0d2e258e1a] Additional work on ticket #3015.

| ||
| 02:45 | Added: [6356013ce1] part of check-in [248b9be93d] In joins of the form: "A, B left C" make sure that the reordering optimization does not put table A after table C. Ticket #1652. (CVS 3052) (check-in: [248b9be93d] user: drh branch: trunk, size: 1435) | |
