15:13 | Alpha-3 (CVS 269) (check-in: a70d445070 user: drh tags: trunk) | |
15:11 | Fixed the support of UNIQUE and PRIMARY KEY. (CVS 268) (check-in: 116fdad068 user: drh tags: trunk) | |
03:22 | Added basic support for enforcement of UNIQUE on indices and primary keys. Support for addition constraints is to follow. (CVS 267) (check-in: 34c42967f3 user: drh tags: trunk) | |
