fetcOnlineContacts != fetchOnlineContacts
But, this isn't the problem, i get the same error. And, i have a
solution for you:
CREATE OR REPLACE FUNCTION fetcOnlineContacts(OUT name text, out organisation text, out email text) RETURNS SETOF record
AS $$
DECLARE
member_contact record;
BEGIN
FOR member_contact IN
EXECUTE 'SELECT DISTINCT ON (m.email)
m.first_name || '' '' || m.last_name AS name,
m.organisation, m.email AS address
FROM member AS m
WHERE m.email IS NOT NULL
ORDER BY m.email, m.last_name, m.organisation ASC'
LOOP
name := member_contact.name;
organisation := member_contact.organisation;
email := member_contact.address;
RETURN NEXT;
END LOOP;
RETURN;
END;
$$
LANGUAGE plpgsql IMMUTABLE;
I hope, you have PG 8.1, this (with the OUT-parameter), is a feature since 8.1.
Perhaps, there are other solutions...
