18:09 | For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Call this the "WHERE-clause push-down optimization". Do not confuse this with the completely different MySQL push-down optimization. (check-in: 6df18e949d user: drh tags: trunk) | |
18:07 | Merge latest trunk changes with this branch. (check-in: c9ffda4abb user: dan tags: fts5) | |
17:25 | Add test cases for type affinity rules. (check-in: 9678646d9a user: drh tags: trunk) | |
16:19 | Rename SQLITE_AFF_NONE to SQLITE_AFF_BLOB to avoid confusion with "no affinity". (check-in: 29ad9e9173 user: drh tags: trunk) | |
