Answer 1

Use the left join (I am assuming table 1 is tbl_marketing)..

SELECT 
      tbl_marketing.* , tbl_phonecall.db_due, tbl_phonecall.db_nextdate
    FROM
      tbl_marketing 
      LEFT JOIN (SELECT db_mid, max(db_due) db_due, max(db_nextdate) db_nextdate FROM tbl_phonecall group by db_mid) tbl_phonecall
        ON tbl_marketing.db_maid = tbl_phonecall.db_mid 
    WHERE tbl_marketing.db_status != 'Deal Done'
      AND tbl_marketing.db_status != 'Refused'
      AND tbl_marketing.db_status != 'Not Interested' 
    ORDER BY tbl_marketing.db_date DESC,
      tbl_phonecall.db_nextdate DESC;
