|23:12||The BETWEEN operator in a WHERE clause is now able to use indices. (CVS 2568) (check-in: cdf8c958 user: drh tags: trunk)|
|20:51||Test cases and tuning of the new optimizer code. (CVS 2567) (check-in: 4b02703d user: drh tags: trunk)|
|16:51||The new optimizer now passes all regression tests. (CVS 2566) (check-in: a2121284 user: drh tags: trunk)|
|20:41||More work on the new optimizer. Fewer tests fail now. (CVS 2565) (check-in: ee3a08e3 user: drh tags: trunk)|
|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)|
|03:18||The results of ANALYZE are now loaded into internal data structures where they can be used. But they are not actually used yet. (CVS 2562) (check-in: 1996bacf 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)|
|23:56||Clarify the meaning of the TEMP keyword on CREATE TABLE. (CVS 2559) (check-in: 1a573619 user: drh tags: trunk)|
|22:53||Correct the documentation to show that sqlite3_column_text() returns a NULL pointer (not an empty string) when the column value is NULL. The same goes for sqlite3_column_blob(). Ticket #1334. (CVS 2558) (check-in: fd1e013a user: drh tags: trunk)|
|00:31||Begin adding code to support multiple IN constraints on the same index. (CVS 2557) (check-in: 103f8ccb user: drh tags: trunk)|
|18:23||Split the OP_Integer opcode into OP_Integer and OP_Int64. This allows comments to be added to OP_Integer. Cleanup in the optimizer. Allow terms of the FROM clause to be reordered automatically. (CVS 2556) (check-in: e2f822ac user: drh tags: trunk)|
