MS Access SQL查询 - 查询表达式中的语法错误(缺少运算符)

Question

我试图理解为什么我的查询(下面)在我运行它时在MS Access Sql查询编辑器(sqlview)中显示错误消息.

SELECT *
FROM tblUSPS
INNER JOIN   tblProductUSPS 
ON tblProductUSPS.[PRODUCTUSPS_USPS] = tblUSPS.[USPS_CODE] 
INNER JOIN  tblAttribute 
ON tblUSPS.USPS_ID = tblAttribute.ATTRIBUTE_USPSID

据我所知,如果我删除任何一个INNER连接线,下面的脚本.例如,此脚本运行时没有错误

SELECT *
FROM tblUSPS
INNER JOIN   tblProductUSPS 
ON tblProductUSPS.[PRODUCTUSPS_USPS] = tblUSPS.[USPS_CODE] 

这也是如此

SELECT *
FROM tblUSPS  
INNER JOIN  tblAttribute ON tblUSPS.USPS_ID = tblAttribute.ATTRIBUTE_USPSID

但是当我结合起来时,出现了问题,我无法找到它,所以我希望得到一些帮助.

Access对括号有强烈意见.

SELECT *
  FROM 
(tblUSPS
INNER JOIN   tblProductUSPS 
   ON tblProductUSPS.[PRODUCTUSPS_USPS] = tblUSPS.[USPS_CODE] )
INNER JOIN  tblAttribute 
   ON tblUSPS.USPS_ID = tblAttribute.ATTRIBUTE_USPSID
