23:52 | Change the ANALYZE command so that it no longer tried to delete unused sqlite_stat2 and sqlite_stat3 tables. Change the DROP TABLE command so that it is able to drop those tables. (check-in: 589f3f5652 user: drh tags: trunk) | |
18:24 | Make sure sqlite3_data_count() behaves as documented, even for EXPLAIN QUERY PLAN queries. (check-in: d4f95b3b6e user: drh tags: trunk) | |
17:52 | Improved handling of OR terms in the WHERE clause with multi-column indexes. (check-in: b23ae13187 user: drh tags: trunk) | |
