I'm not sure if you want to improve the query, or the replication process. If it's the replication process, one other option is 'refresh force'. Then, if I understand the docs correctly, you get a fast refresh if it can; and if refresh fast is not possible, then refresh complete. That's the theory. Now whether or not it actually works that way ....

For what it's worth, I always use 'refresh force'.

-----Original Message-----

How can I create materialized view(mv) for the following statement using 'refresh fast' method.
I can use 'refresh complete' option to create this mv, but how can I use 'refresh fast' option for the below statement in order to improve performance in query.
Any workaround ?

select mas.salesrep_id,sum(del.qty*del.price)-sum(del.discount) from
sales_master mas,
sales_details del
where
mas.transaction_id =del.transaction_id
group by
mas.salesrep_id.

Thanks in advance
