| 20:16 | Extend [3e9ed1ae] so that covering indexes on WITHOUT ROWID tables are also identified. (check-in: e721975f user: dan tags: trunk) | |
| 19:57 | Change a char* to const char* in order to suppress some harmless compiler warnings. (check-in: 56f62e34 user: drh tags: trunk) | |
| 17:18 | When an index completely covers a table, it can be used as a covering index even if columns past the 63rd column are indexed and accessed. (check-in: 3e9ed1ae user: drh tags: trunk) | |
