Such information is not kept by the SQLite library. It should be easy for an application to keep track of this. (I'm not sure what a "database name" or "handle" are in this context, but can answer nonetheless because the library does not rely on in-process data other than what is kept in per-connection structs or in structs held by them.) Also: Please choose more descriptive thread titles going forward. Yours is ambiguous at best and misleading at worst.
