다른 1064 구문 오류

Question

이 구문의 잘못된 점을 파악할 수 없습니다. 마지막 줄에 # 1064 구문 오류가 발생합니다.

SELECT b.id, b.lastname, b.name, c.balance, a.maxdebt, b.warndata, b.warndownload, b.warnupload, b.warndebt, b.cutoffdata, b.cutoffdownload, b.cutoffupload, b.cutoffdebt, b.data, b.download, b.upload, b.warning, b.access, b.cutoffstop 
FROM (
SELECT customers.id AS id, SUM(tariffs.value) AS maxdebt 
      FROM tariffs 
      INNER JOIN assignments ON tariffs.id = assignments.tariffid 
      INNER JOIN customers ON assignments.customerid = customers.id 
      GROUP BY id 
) a 
LEFT JOIN (
SELECT customers.id AS id, UPPER(lastname) AS lastname, customers.name AS name, SUM(stats.upload+stats.download) AS data, SUM(stats.download) AS download, SUM(stats.upload) AS upload, cutoffstop, warndata, warndownload, warnupload, warndebt, cutoffdata, cutoffdownload, cutoffupload, cutoffdebt, warning, access 
     FROM customers 
     LEFT JOIN nodes ON customers.id = nodes.ownerid 
     LEFT JOIN stats ON nodes.id = stats.nodeid 
     LEFT JOIN customerwarnings ON customers.id = customerwarnings.id 
    GROUP BY id 
) b 
LEFT JOIN (
SELECT customerid, SUM(cash.value) AS balance 
     FROM cash 
     GROUP BY customerid 
) c ON a.id = b.id = c.customerid 

나는 오른쪽으로 테이블을 조인 시도하고 LEFT는 차이가 있는지 확인하기 위해 조인 그러나 그들은 나에게 같은 오류를 제공합니다. 다른 쿼리가 잘 작동하지만,이 쿼리에서이 쿼리를 함께 사용하면 구문 오류가 발생합니다. 누구든지 내가해야하거나하지 말아야 할 아이디어가 있습니까?
