I assume you wrapped script with CDATA? Other it will produce invalid DS XML.

Please, be consistent, use only single quotes :) This save several milliseconds for each request.

Resource leak: recordset is not freed. You'll get lots of memory leaks in Apache/MySQL if you use persistent MySQL connections.
