獲得MySQL錯誤1054

Question

我收到此錯誤：＃1054 - 未知列「t.mobile」在「關於條款」

SELECT t.*,v.name,v.contact_person_email,l.firstname as memname 
FROM transactions t , vendor v 
LEFT JOIN loyalty_members l ON (t.mobile=l.mobile) 
WHERE t.vendor_id ='N1WU95' 
AND v.alert_mail = '2' 
AND t.add_date <= '2011-07-22 09:00:00' 
AND t.add_date >= '2011-07-21 09:00:00' 
AND t.vendor_id = v.id 
AND t.type = '1' 
AND t.deleted != '1' 
AND t.reference_id = '0' 
GROUP BY t.mobile 
HAVING COUNT(t.mobile) > 1; 

任何人都可以請幫我解決了這一點？

謝謝。

Answer 1

嘗試：

SELECT t.*, v.name, v.contact_person_email, l.firstname memname 
    FROM vendor v, transactions t 
LEFT JOIN loyalty_members l ON t.mobile = l.mobile 
    WHERE t.vendor_id ='N1WU95' 
     AND v.alert_mail = '2' 
     AND t.add_date <= '2011-07-22 09:00:00' 
     AND t.add_date >= '2011-07-21 09:00:00' 
     AND t.vendor_id = v.id 
     AND t.type = '1' 
     AND t.deleted != '1' 
     AND t.reference_id = '0' 
GROUP BY t.mobile 
    HAVING COUNT(t.mobile) > 1; 

你在做一個LEFT JOIN與錯誤的表順序。引擎試圖加入vendor表與loyalty_members表。

簡而言之，表transactions中的「移動」列不存在。
