| 17:36 | The USING clause and NATURAL JOIN look at all tables to the left when searching for a match, not just the one table to the immediate left. Tables further to the left are preferred. Fix for ticket [f74beaabde]. Still need to add test cases to complete the ticket. (check-in: b558e96f user: drh tags: trunk) | |
| 14:39 | Improve test coverage of fts3.c. (check-in: 56b6432f user: dan tags: trunk) | |
| 05:30 | Mark fts3ReallocOrFree and fts3InitVtab as static. Ticket [ff44d82f3b]. (check-in: a9038306 user: dan tags: trunk) | |
