      refresh complete start with (sysdate) next  (sysdate+1/1440) with rowid
        as select * from temp;

Steg 3:

select count(*) from temp;

       COUNT(*)
      ----------
          0

Steg 4:

select count(*) from temp_mv;

       COUNT(*)
       ----------

      for i in 1..10 loop
         insert into temp values (i+1);
      end loop;
end;
