RE: Whats the Concept of Flashback Query?
It lets you to view and repair historical data.They  query the database by TIME or user specified SCN.    It do not UNDO anything .It is only a query mechanism.You can take o/p from flashback query and perform an undo yourself.
It do not work through DDL operation.
for example,   the data before 5 minutes which has lost is repaired as-

       execute  dbms_flashback.enable_at_time(sysdate-5/1440);
         
       ............................................
          execute dbms_flashback.disable
