Question

有人可以帮忙解决此问题吗？我尝试了几乎没有运气的事情。

我有以下MySQL查询，它会吐出以下错误

错误： 'on clause'

中的未知列'SR.sales_rec_id'

QUERY：

SELECT 
  SYSKEY.cri_sr_id,
  SR.sales_rec_id,
  SYSKEY.adnum,
  charge,
  SYSKEY.cancelsale,
  paymentdue,
  merchant,
  paymentnum,
  authorization as authcode,
  CONCAT(lastname,', ',firstname,' ',middleinitial) as customer, 
  CONCAT(replname,', ',repfname) as repname,    
FROM CRI_SR_KEYS as SYSKEY
  INNER JOIN SALES_PENDING as SPEND on SPEND.sales_rec_id=SR.sales_rec_id
  INNER JOIN SALES_RECORD as SR on SR.cri_sr_id=SYSKEY.cri_sr_id 
  LEFT JOIN CLIENT_INFO as CI on CI.client_id = SYSKEY.clientid 
  LEFT JOIN SALES_REPS as REP on SR.rep_id=REP.repid    
WHERE SPEND.authorization NOT LIKE '000000' AND paymentdue LIKE CURDATE() 
ORDER BY adnum ASC LIMIT 0,5000

Answer 1

重新排列联接的顺序，以便在您尝试使用之前SR有别名：

SELECT 
  SYSKEY.cri_sr_id,SR.sales_rec_id,
  SYSKEY.adnum,charge,
  SYSKEY.cancelsale,paymentdue,merchant,paymentnum,authorization as authcode,
  CONCAT(lastname,', ',firstname,' ',middleinitial) as customer, 
  CONCAT(replname,', ',repfname) as repname    
FROM CRI_SR_KEYS as SYSKEY
  INNER JOIN SALES_RECORD as SR on SR.cri_sr_id=SYSKEY.cri_sr_id 
  INNER JOIN SALES_PENDING as SPEND on SPEND.sales_rec_id=SR.sales_rec_id
  LEFT JOIN CLIENT_INFO as CI on CI.client_id = SYSKEY.clientid 
  LEFT JOIN SALES_REPS as REP on SR.rep_id=REP.repid    
WHERE SPEND.authorization NOT LIKE '000000' AND paymentdue LIKE CURDATE() 
ORDER BY adnum ASC LIMIT 0,5000

在SELECT子句中repname之后还有一个逗号，但这可能只是一个错字。

Answer 2

如果列SALES_RECORD.sales_rec_id确实存在，请重新排序JOIN语句：

FROM CRI_SR_KEYS as SYSKEY
  /* Move this above SALES_PENDING to SR */
  INNER JOIN SALES_RECORD as SR on SR.cri_sr_id=SYSKEY.cri_sr_id 
  INNER JOIN SALES_PENDING as SPEND on SPEND.sales_rec_id=SR.sales_rec_id
  LEFT JOIN CLIENT_INFO as CI on CI.client_id = SYSKEY.clientid 
  LEFT JOIN SALES_REPS as REP on SR.rep_id=REP.repid

如何修复MySQL查询以解决“未知列...在On子句中”错误？
