| 15:34 | Add test cases for UPSERT. And a fix for a "REPLACE INTO ... ON CONFLICT" statement where the new row conflicts with both the IPK and the ON CONFLICT indexes. (check-in: d8eb9f8d9b user: dan tags: trunk) | |
| 13:18 | Enhance UPSERT so that the UPDATE uses the same set of cursors as the INSERT. (check-in: c37f39d18d user: drh tags: trunk) | |
| 00:40 | Minor simplification of the cursor allocation logic for update. (check-in: fdf71be658 user: drh tags: trunk) | |
