| 04:50 | Add some comments to query planner code. Also replace some TAB characters with 8 spaces in where.c. check-in: 7ddc35dcb3 user: dan tags: pager-refactor-1 | |
| 01:42 | Further changes to bestBtreeIndex(). check-in: 09c0fd6676 user: dan tags: pager-refactor-1 | |
|
2009-08-12
| ||
| 12:07 | Prefer "optimal" scans to non-optimal when ordering tables. This version works for virtual and b-tree tables. check-in: 75cc38e985 user: dan tags: pager-refactor-1 | |
| 06:33 | Changes to bestBtreeIndex(). check-in: d67784ac60 user: dan tags: pager-refactor-1 | |
| 04:37 | Update to cvs trunk. check-in: 1bdff789e4 user: dan tags: pager-refactor-1 | |

| 13:46 | Sync against CVS 6968 Leaf check-in: 8fb3799757 user: drh tags: trunk | |
|
2009-08-08
| ||
| 09:29 | Fix collation sequence handling in code to estimate the expense of a range scan. Leaf check-in: 359e8cb31b user: dan tags: pager-refactor-1 | |
|
2009-08-07
| ||
| 15:43 | Add experimental implementation of the sqlite_stat2 table. This table stores evenly spaced data samples read from an index b-tree. It can be used to optimize range queries on the index when the required range is available at compile time (ie. when it is specified using SQL literals, not bound variables or other expressions). check-in: 929ed8a4cc user: dan tags: pager-refactor-1 | |

| 03:52 | Temp check-in to report pager stats for testing. Leaf check-in: 3705073d2e user: shaneh tags: trunk | |
| 01:34 | Sync with cvs 6958. check-in: 3bc50ac874 user: dan tags: pager-refactor-1 | |

| 16:56 | Updated the greedy algorithm to use the optimal-actual cost delta instead of actual cost for scan selection. check-in: 7019639732 user: shaneh tags: trunk | |
| 06:24 | Changes to the query planner heuristics to hopefully improve index selection when "similar" indexes are available. A coverage cost reduction was added to reduce the cost of an index for each term it "covers" in the where clause. Similarly, in the case of a tie, the preference is given to the smaller index. There are a few test case failures in eqp.test and where7.test that I am investigating. check-in: 38620d8696 user: shaneh tags: trunk | |
