| 22:50 | Enable query planner tracing using the new (and undocumented) ".wheretrace 1" command in the command-line shell if both the shell and the core are compiled with SQLITE_DEBUG and SQLITE_ENABLE_WHERETRACE. This is not a supported API. Use for testing and debugging only. check-in: 1be4b16b user: drh tags: trunk | |
