获得MySQL错误1054

Question

我收到此错误：＃1054 - 未知列“t.mobile”在“关于条款”

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; 

任何人都可以请帮我解决了这一点？

谢谢。

Answer 1

尝试：

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; 

你在做一个LEFT JOIN与错误的表顺序。引擎试图加入vendor表与loyalty_members表。

简而言之，表transactions中的“移动”列不存在。
