I am not sure what you want.  There are a lot of options for materialized views.  For instance, the following is a modified example of an aggregate view from the Oracle documentation.  You can then refresh it by using the DBMS_REFRESH package.

Is it the DBMS_REFRESH package that you need help on?  If not could you be more specific about what you want, and I can perhaps give you the SQL.

   AS SELECT t.calendar_year, p.prod_id,
      SUM(s.amount_sold) AS sum_sales
      FROM times t, products p, sales s
      WHERE t.time_id = s.time_id AND p.prod_id = s.prod_id
      GROUP BY t.calendar_year, p.prod_id;

Thx for the reply ,But please include the syntax also  the clause for refresh of the view  in every two hours also.
The syntax is:

Create materialized view [view name]
refresh fast next sysdate + 1/12
select ...
from ...
where ...

this will do a fast refresh every two H`s, starting from two H`s after view creation.

Thx please send me the syntax for creation of group in dbms_refresh and using dbms_refesh for the group.And when we are using dbms_refresh we should use use refresh fast next sysdate + 1/12  in view or not.And if we not using then what is the syntax for creation of  materilaized view with dbms_refresh.
This is urgent please reply.
Thx in advance.,

Here is the full syntax plus examples of the dbms_refresh procedure.

As for the view creation, if you don`t want it to do an automatic refresh, just omit the refresh clause and use the dbms_refresh to do it manualy.
