| 02:43 | The ALTER TABLE command should not attempt to rename objects that are contained within an expression tree that has been optimized out because it is the other branch of an "AND false" expression. Ticket [533010b8cacebe82] check-in: 04bd5cb7 user: drh tags: trunk | |
| 01:56 | Fix repeated test numbers in the altertab2.test file. check-in: e82f235e user: drh tags: trunk | |
