Answer 1

Select the rowid for the row, and the DBMS_RowID.RowID_Object() procedure will extract the data object id.

http://docs.oracle.com/cd/B19306_01/appdev.102/b14258/d_rowid.htm#i997153

Look up that data object id in the data dictionary and read the subobject_name.

For example:

   SELECT dbms_rowid.rowid_object(ROWID) data_object_id
   FROM INVOICE
   WHERE INVOICE_ID = 2268041139:

   -- data_object_id = 546512

   select * from user_objects where data_object_id = 546512;

   -- SUBOBJECT_NAME = 'PART_P2099_P00'     
   -- OBJECT_TYPE = TABLE PARTITION
   -- OBJECT_ID = 464826
   -- DATA_OBJECT_ID = 546512
