I think your method for doing this should depend upon what "when it was created" means. If it means "before any tables (or table-like objects) and/or data were created, but after certain non-default DB-wide settings were established", then you can drop all the views, indices and tables, then do a SQL VACUUM. If things were done after the sqlite3_open call, such that the "created" state differs from the empty state all that dropping produces, then you will need to undo (where you can) the settings that are different. See the [pragma list](https://sqlite.org/pragma.html#toc) to peruse what those settings might be.
