| 18:32 | Take into account the cost of inner loops when selecting which table of a join to use for the next outer loop. check-in: 3f87f459 user: drh tags: trunk | |
| 18:22 | Disable the table selection rule that tried to prevent full table scans from migrating to the outer loop unless they were optimal. The new scaling of outer-loop costs by cost of inner loops obviates the need for that step. And, in fact, that step causes problems with the new inner-loop cost accounting.
