Wouldn't a simple GROUP BY work?:
SELECT Country.* FROM cake_countries AS Country JOIN cake_members AS
Member ON Country.id=Member.country_id GROUP BY Country.id
or
SELECT Country.* FROM cake_members AS Member JOIN cake_countries AS
Country on Country.id=Member.country_id GROUP BY country_id HAVING
COUNT(country_id)>1
The first query should only list countries with more than 1 member,
whereas the second query allows you to specify an arbitrary number of
members you want filter by (e.g. countries with more than 5 members).
You can probably also achieve the same thing with subqueries, but I
haven't figured it out.
