Skaber materialiseret visning, der opdateres hvert 5. min

Jeg har demonstreret i trin, hvor en materialiseret visning opdateres efter hvert one minute ,for at have en mv, der opdateres efter 5 minutter, brug next(sysdate+5/1440)

Trin 1:

Create table temp (A int);

Trin 2:

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

Trin 3:

select count(*) from temp;

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

Trin 4:

select count(*) from temp_mv;

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

Trin 5:

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

Trin 6:

commit;

Trin 7:

select count(*) from temp;

      COUNT(*)
     ----------
        10

Trin 8:

select count(*) from temp_mv;

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

Trin 9:

select to_char(sysdate,'hh:mi') from dual;

       TO_CH
       -----
       04:28

Trin 10:

select to_char(sysdate,'hh:mi') from dual;

       TO_CH
        -----
       04:29

Trin 11:

select count(*) from temp;

      COUNT(*)
     ----------
        10

Trin 12:

select count(*) from temp_mv;

      COUNT(*)
      ----------
         10
