I'm having difficulty writing a query as follows. I'm unsure if I need a
subquery, a union or if this isn't actually possible without using
temporary tables.
I have two tables for members.
Table 1 (members) Table 2 (payments)
+--++ +-+--+
| memno
Is this what you're after?
SELECT
COUNT(*) AS members,
SUM(IF(payment_type = 'creditcard', 1, 0)) AS pay_by_card
FROM
members
JOIN payments USING (memno)
GROUP BY group;

Thanks for the two incredibly fast responses, they were perfect -
problem solved.
