如何加入此查詢

Question

我有這個查詢命令，但我想使用JOIN命令，我該怎麼做。

SELECT `tkb_code`, `tko_code`, `sch_no`, `tkb_sea_name`, `tkb_mem_name`, 
     `tkb_BusStop_price`,`tkh_comment`, `tks_id`, `tkr_text`, `sale_f`, 
     `tkh_date` 
FROM `ticket_booking` 
WHERE tkh_updateby =60 AND tks_id =3 AND date(tkh_date) = '2013-05-15' AND sale_f =1 
AND tkb_code NOT IN (
    SELECT tkb_code 
    FROM `ticket_booking` 
    WHERE tks_id =3 AND date(tkh_date) = '2013-05-14' 
    ) 
AND tkb_code NOT IN (
    SELECT tkb_code 
    FROM `ticket_booking` 
    WHERE tks_id =6 AND date(tkh_date) = '2013-05-15' AND tkh_updateby =60 
    AND tkb_code IN (
     SELECT tkb_code 
     FROM ticket_booking 
     WHERE tks_id =3 
     ) 
    ) 
GROUP BY tkb_code 
ORDER BY tkh_date, tkb_sea_name 

有人告訴我，使用JOIN時性能很好。我想替換我的查詢。

嘗試：

SELECT t.`tkb_code`, 
     t.`tko_code`, 
     t.`sch_no`, 
     t.`tkb_sea_name`, 
     t.`tkb_mem_name`, 
     t.`tkb_BusStop_price`, 
     t.`tkh_comment`, 
     t.`tks_id`, 
     t.`tkr_text`, 
     t.`sale_f`, 
     t.`tkh_date` 
FROM `ticket_booking` t 
LEFT JOIN `ticket_booking` ty 
     ON t.tkb_code = ty.tkb_code AND 
      ty.tks_id=3 AND 
      date(ty.tkh_date) = '2013-05-14' 
LEFT JOIN `ticket_booking` t6 
      JOIN `ticket_booking` t3 
      ON t6.tkb_code = t3.tkb_code and t3.tks_id =3 
     ON t.tkb_code = t6.tkb_code AND 
      t6.tks_id=6 AND 
      date(t6.tkh_date) = '2013-05-15' AND 
      t6.tkh_updateby =60 
WHERE t.tkh_updateby=60 AND 
     t.tks_id=3 AND 
     date(t.tkh_date) = '2013-05-15' AND 
     t.sale_f=1 AND 
     ty.tkb_code IS NULL AND 
     t6.tkb_code IS NULL 
GROUP BY t.tkb_code 
ORDER BY t.tkh_date, t.tkb_sea_name
