| 13:02 | Merge trunk enhancements, and espeically the fix for allowing strings as column identifers in CREATE INDEX statements. Closed-Leaf check-in: 5ff85529 user: drh tags: index-expr | |

| ||
| 13:17 | Rename SQLITE_FUNC_VARYING to SQLITE_FUNC_SLOCHNG - a more descriptive name for what that bit means. check-in: ff5137a6 user: drh tags: index-expr | |
| 00:42 | Remove unreachable branches. check-in: fd4da231 user: drh tags: index-expr | |

| ||
| 23:09 | Fix a bug in error reporting when a UNIQUE index on expressions fails its uniqueness test. check-in: 5a2c0e90 user: drh tags: index-expr | |
| 21:16 | Not only date/time functions, but also functions like sqlite_version() and changes() need to be prohibited from use inside of indexes. check-in: 48713130 user: drh tags: index-expr | |
| 19:38 | Always assume that indexed expressions can generate a NULL. Get indexed expressions working for the case of two or more expressions in the same index. check-in: cc60321a user: drh tags: index-expr | |
| 18:13 | Case should not be significant when comparing function names. check-in: e2f1caf1 user: drh tags: index-expr | |
| 17:34 | Make the distinction between truly deterministic functions and date/time functions which only return the same answer for a single query. Only truly deterministic functions are allowed in indexes. Add new expression index test cases. check-in: c77554b5 user: drh tags: index-expr | |
| 15:58 | Improved analysis and usage of indexed expressions in the query planner. check-in: f8893696 user: drh tags: index-expr | |
| 14:27 | Merge the latest enhancements from trunk. check-in: 7bde6d4d user: drh tags: index-expr | |

| ||
| 23:42 | Fix the OR-optimization so that it always ignores subplans that do not use an index. check-in: cf452028 user: drh tags: index-expr | |
| 20:33 | Fix EXPLAIN QUERY PLAN output for indexed-expressions. Fix another obscure fault in the WHERE term scanner. check-in: 73d361ce user: drh tags: index-expr | |
| 19:56 | Fix problems in the indexed-expression handling in the optimizer. check-in: 03375017 user: drh tags: index-expr | |
| 18:24 | Activate the ability to use expressions in indexes in a query. There are some test failures, but mostly this seems to work. check-in: 42f93f58 user: drh tags: index-expr | |
| 16:07 | Merge changes from trunk. check-in: c80e9e8e user: drh tags: index-expr | |
| 15:58 | Adjustments to the WHERE term scanning, to better handle scanning terms of an index. check-in: 5611130a user: drh tags: index-expr | |

| 19:24 | Merge trunk enhancements. check-in: e8b02902 user: drh tags: index-expr | |
| 16:57 | Add code to maintain indexes with expression arguments across DELETE, INSERT, and UPDATE statements. Legacy tests pass, but the new code paths are still largely untested. The query planner currently makes no effort to use expression indexes. check-in: efaabdb7 user: drh tags: index-expr | |
| 00:27 | Changes toward being able to process indexes on expressions. Not there yet - this check-in is just movement in that direction. Some tests are failing. check-in: 0ad0f8d7 user: drh tags: index-expr | |
