| 20:32 | [3da2f5c8] part of check-in [3ceae357] Add another test case for the "x IS NULL" uniqueness problem of ticket #3824. No changes to code. This just double-checks that everything is working now. (CVS 6548) (check-in: [3ceae357] user: drh branch: trunk, size: 2597) | |
| 14:51 | [df7c288c] part of check-in [207335fd] Make sure that the optimizer realizes that an "x IS NULL" contraint does not necessarily give a single-row result even on a UNIQUE index. Ticket #3824. (CVS 6545) (check-in: [207335fd] user: drh branch: trunk, size: 2279) Added | |
