15:10 | Optimizer now converts OR-connected WHERE-clause terms into an IN operator so that they can be used with indices. There are known problems with the ORDER BY optimization in this and in several prior check-ins. This check-in is not recommended for production use. (CVS 2569) (check-in: d23c8bf8 user: drh tags: trunk) | |
2005-07-28
| ||
23:12 | The BETWEEN operator in a WHERE clause is now able to use indices. (CVS 2568) (check-in: cdf8c958 user: drh tags: trunk) | |

2005-07-27
| ||
20:41 | More work on the new optimizer. Fewer tests fail now. (CVS 2565) (check-in: ee3a08e3 user: drh tags: trunk) | |
2005-07-23
| ||
22:59 | A new optimizer that breaks a lot of tests. But none of them critically, I think. Nevertheless, there is a lot of work ahead to stabilize the code. (CVS 2564) (check-in: 86ce56cc user: drh tags: trunk) | |
14:52 | Store the total number of rows as part of the ANALYZE statistics. (CVS 2563) (check-in: 868279c7 user: drh tags: trunk) | |

02:17 | Full-coverage testing and documentation for the ANALYZE command. The results of analysis are still not loaded or used, however. (CVS 2561) (check-in: bd7583a5 user: drh tags: trunk) | |
00:41 | First code for the ANALYZE command. Mostly untested. The analysis is not loaded into the symbol tables and is not used by the optimizer. (CVS 2560) (check-in: a4886b11 user: drh tags: trunk) | |
2005-07-22
