Multiple WHERE conditions - Not sure about this post

Hi,

I killed my last post and am posting a new one with an updated query. Hopefully the other one was deleted.

Anyhow, I want to retrieve 2 records based on different criteria and am hoping not to do a union or anything since 95% of the criteria is the same.

SELECT customer_id, first_name, last_name, email, order_date, order_id, status, subscr_type
FROM (SELECT c.customer_id, first_name, last_name, email, order_date, ol.order_id, p.product_id, p.code, ol.status, subscr_type, ROW_NUMBER
()

      OVER (PARTITION BY c.customer_id ORDER BY c.customer_id) cnt
      FROM customer c, customer_account ca, customer_order co,
order_line ol, product p, newsletter_subscription ns
      WHERE c.customer_id = co.customer_id
        AND c.customer_id = ca.customer_id
        AND co.order_id   = ol.order_id
        AND ol.product_id = p.product_id
        AND p.code = ns.code
        AND p.subproduct_id = 197
        AND (ns.subscr_type =  'Trial' AND TRUNC(co.order_date) = TRUNC


(SYSDATE - 60) AND ol.status =  'Complete')

        AND (ns.subscr_type <> 'Trial' AND TRUNC(co.order_date) = TRUNC

But, what I am really looking for is that I want customers who have purchased a 'Trial' 60 days ago with a status of 'Complete', and ALSO have on their account a 'Non-Trial' order with a status of 'Active' or Cancelled' purchased 30 days ago.

So, customers who have a 'Complete' Trial ordered 60 days ago, and now are 'Active' or 'Cancelled' with a Non-Trial ordered 30 days ago.

I'm hoping to do this in one query using analytical functions of something, rather than some union or PL/SQL code.... Received on Fri Mar 13 2009 - 10:31:13 CDT
