Judging from the documentation there is not (optional methods may have a NULL pointer in the method table). Maybe this will/has change(d)
2.12 The xRowid Method int (*xRowid)(sqlite3_vtab_cursor *pCur, sqlite_int64 *pRowid); A successful invocation of this method will cause *pRowid to be filled with the rowid of row that the virtual table cursor pCur is currently pointing at. This method returns SQLITE_OK on success. It returns an appropriate error code on failure. The xRowid method is required for every virtual table implementation. -----Ursprüngliche Nachricht----- Von: Max Vlasov [mailto:max.vla...@gmail.com] Gesendet: Freitag, 09.
