Group By?

Hi All,

I have the following query. For a few records, it returns duplicate CUSTOMER_ID's, though the rest of the record values are different.

I want 1 record per CUSTOMER_ID, regardless of the other values.

   SELECT co.customer_id c_id, engine.calc_end_date (co.order_date, p.quantity, p.quantity_uom) end_date,

          DECODE(ns.subscr_type, 'Trial', 'Trial', 'Test', 'Trial', 'Paid') subscr_type

   FROM engine.customer_order co, engine.order_line ol, engine.product p, product.newsletter_subscription ns

   WHERE co.order_id = ol.order_id
   AND ol.product_id = p.product_id
   AND p.code = ns.code
   AND p.subproduct_id IN (197, 202, 209, 216, 220, 222)    AND ol.status = 'Active'
   ORDER BY co.customer_id;
