if you want see account_status and the count()- try this:
SELECT
CASE
WHEN AND c.regdate > EXTRACT(epoch FROM (now() - INTERVAL '14 day'))
THEN 'trial'
WHEN last_pay > EXTRACT(epoch FROM (now() - INTERVAL '37 day'))
THEN 'paying'
END as account_status,
count(*)
FROM public.clients c
WHERE (
(last_pay > EXTRACT('epoch' FROM now() - '12 Months'::INTERVAL))
)
group by 1
ORDER BY 1

comparisons like "A>B" return a boolean. Booleans can be cast to integers, and integers can be summed.
SUM((A>B)::int)
But depending on the situation, indexes etc it could be faster to run e separate count query, you'll have to test that.Could you please guys give me a query as an example?ThanksP.
