David,

I have modified the first query to my needs and I believe, it gives the
correct results for the first time orders.

accept


WITH first_cust_cte AS 
( 
        SELECT min(ord_submitted_date)ord_date 
                , persistent_key_str 
        FROM orders 
        group by persistent_key_str 
) 
SELECT o.persistent_key_str, o.ord_id 
 FROM orders o INNER JOIN first_cust_cte c 
 ON o.persistent_key_str = c.persistent_key_str AND  o.ord_submitted_date =
c.ord_date

Thanks for your support.

Thanks,

Ron
