| 18:52 | Change the sqlite3_namelist() interface to return a pointer to an array of pointers to strings, and to avoid duplicates. (check-in: 7029111044 user: drh tags: experimental-namelist) | |
| 18:25 | The sqlite3_namelist() routine now works for all name types. (check-in: e41d62175b user: drh tags: experimental-namelist) | |
| 17:36 | Initial implementation of a highly experimental interface for listing all keywords and symbolic names for an SQLite database connection. (check-in: 04ef6783a5 user: drh tags: experimental-namelist) | |
