21:11 | Minor changes to the CAST logic to make it more testable. (check-in: 1ad70ec550 user: drh tags: trunk) | |

20:11 | Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0b7 user: drh tags: trunk) | |
