Optimizer now converts OR-connected WHERE-clause terms into an IN operator so that they can be used with indices.

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)

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)
2005-07-21
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)
03:48

2005-07-08
18:25
Allow the IN operator to take a list of arbitrary expressions on its right-hand side. The expressions no longer need to be constant. The current implementation seems to work but needs more testing and optimization. (CVS 2542) (check-in: ba56478d user: drh tags: trunk)
17:13
Change the name of the OpenTemp opcode to OpenVirtual which is more descriptive of what it does. (CVS 2541) (check-in: 3bb9ce5f user: drh tags: trunk)
