A CGI::Application based app that I'm developing for a client uses the following query:
SELECT FirstName, LastName, PhoneNumber, members.MemberID AS MemberID FROM members LEFT JOIN phone_numbers ON ( members.MemberID=phone_numbers.MemberID AND phone_numbers.PhoneNumberID IN (SELECT MIN(PhoneNumberID) FROM pho +ne_numbers GROUP BY MemberID) ) WHERE Verified=1 ORDER BY LastName, FirstName, members.MemberID;

Unfortunately, their host is using MySQL 4.0, which doesn't support subqueries (subqueries were introduced in MySQL 4.1). Can this query be rewritten as a single query without subqueries, or should I take some of the logic out of the query and rewrite it in Perl?
