| 15:08 | Enhance the built-in date/time functions so that they can be used in CHECK constraints, in the WHERE clause or partial indexes, and index expressions, provided that none of the non-deterministic keywords ("now", "localtime", "utc") are used as arguments. (check-in: a90c062d46 user: drh tags: trunk) | |
| 14:36 | New test cases for date/time functions in indexes on expressions, in the WHERE clause of partial indexes, and in CHECK constraints. (Closed-Leaf check-in: b7f70c7fca user: drh tags: index-on-date-func) | |
| 13:17 | Combine the Parse.ckBase and Parse.iSelfTab fields into just Parse.iSelfTab. This fixes a problem with date/time functions in check-constraints. Add some test cases for date/time functions in index expressions and check constraints. (check-in: 22eda0985e user: drh tags: index-on-date-func) | |
