This is urgent please reply.
Thx in advance.,
http://www.dbasupport.com/
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.

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.
CREATE MATERIALIZED VIEW sales_mv
BUILD IMMEDIATE
REFRESH COMPLETE ON DEMAND
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;
