如何提高此查询的性能？

Question

我有以下MySQL查询，需要的时间超过421ms我该如何优化？

SELECT j.*, c.cl_business_name, c.cl_short_name, 
      m.me_last_name, m.me_first_name, o.co_name, j.jo_deleted_date 
FROM clients c, companies o, jobs j 
LEFT JOIN members m ON j.me_id = m.me_id 
WHERE ? AND j.jo_deleted = ? AND j.co_id = o.co_id AND j.cl_id = c.cl_id 
ORDER BY jo_deleted_date DESC
