Creating a Materialized view with fast refresh and on Demand option create materialized view XXARG_GOKU
AS 
select 
XDR.GLOBAL_ID
XDR.PARTY_ID,
XDR.EMAIL_ADDRESS,
XDU.CITY_CODE,
XDU.STD_CODE,
XDU.PIN_CODE_SERIAL_NO
from XXARG_DUMMY XDU, XXARG_DRAGON XDR

I need a query for creating fast refresh with on demand option. I have already created MLOG$_XXARG_DUMMY and MLOG$_XXARG_DRAGON mlog tables for it. 

Please note: the above query is for creating a Materialised view and I'm using oracle 10g DB
Restrictions on Fast Refresh on Materialized Views with Joins Only
  
  Defining queries for materialized views with joins only and no aggregates have the following restrictions on fast refresh:
  
  They cannot have GROUP BY clauses or aggregates.
  
  Rowids of all the tables in the FROM list must appear in the SELECT list of the query.
  
  Materialized view logs must exist with rowids for all the base tables in the FROM list of the query.
