오류 : '필드 목록'의 알 수없는 열

Question

다음 쿼리를 실행할 때 열 ls.amount가 필드 목록에 있음 오류가 발생합니다.

누구든지 나를 진단 할 수 있습니다.

SELECT c.name, ic.keyword, COUNT(ic.keyword), SUM(ls.amount), ls.buyer FROM in_clicks AS ic 
     INNER JOIN ads AS a ON ic.ad_id = a.id 
     INNER JOIN ad_groups AS ag ON a.ad_group_id = ag.id 
     INNER JOIN campaigns AS c ON ag.campaign_id = c.id; 
     INNER JOIN leads AS l ON (ic.id = l.in_click_id) 
     INNER JOIN lead_status AS ls ON (l.id = ls.lead_id) 
WHERE ic.create_date LIKE '%2011-08-19%' AND ic.location NOT LIKE '%Littleton%' AND discriminator LIKE '%AUTO_POST%' 
GROUP BY ic.keyword ORDER BY COUNT(ic.keyword) DESC 

정확한 오류 메시지는 다음과 같습니다

Error Code: 1054
