Yes, I was also looking at analytical functions.
The query works fine if both conditions on both SELECT statements are positive, but if one is negative, the entire query fails.
The actual query I've been trying to work with is:
SELECT customer_id, non_ut_subscr_id, non_ut_product_id, non_ut_status, ut_subscr_id, ut_product_id, ut_status FROM (SELECT customer_id, subscription_id non_ut_subscr_id, produst_id non_ut_product_id,
SUM(status) OVER (PARTITION BY customer_id) non_ut_status
FROM subscriptions WHERE customer_id = p_customer_id AND produst_id <> 204), (SELECT customer_id, subscription_id ut_subscr_id, produst_id ut_product_id, SUM(status) OVER (PARTITION BY customer_id) ut_status FROM subscriptions WHERE customer_id = p_customer_id AND produst_id = 204);
I want it all in one line. So, that is what I am trying to work with. I'm sure it can be done, just have to figure out the exact syntax.
