先生，我有问题，我有这个问题

"SELECT alumni.`ID NO`, alumni.`LAST NAME`, alumni.`GIVEN NAME_MI`, 
alumni.`COURSE`, courses.`CollegeID`, office365alumni.`EmailAddress`, 
office365alumni.`ContactNumber` 
FROM alumni 
LEFT JOIN courses ON alumni.`COURSE` = courses.`ID` 
LEFT JOIN office365alumni ON alumni.`ID NO` = office365alumni.`IDNumber` 
WHERE alumni.`ID NO` = @IDNumber"

它给了我错误

syntax error (missing operator) in query expression
 'alumni.`COURSE` = courses.`ID` LEFT JOIN office365alumni 
ON alumni.`ID NO` = office365alumni.`IDNumber'.

我的查询有什么问题？谢谢

【解决方案1】：

您的列名中有空格。将列名用方括号括起来，然后看看你是怎么做的：

SELECT 
    alumni.[ID NO], 
    alumni.[LAST NAME], 
    alumni.[GIVEN NAME_MI], 
    alumni.[COURSE], 
    courses.[CollegeID], 
    office365alumni.[EmailAddress], 
    office365alumni.[ContactNumber] 
FROM 
    (alumni 
    LEFT JOIN courses ON alumni.[COURSE] = courses.[ID])
    LEFT JOIN office365alumni ON alumni.[ID NO] = office365alumni.[IDNumber] 
WHERE alumni.[ID NO] = @IDNumber

先生，我仍然遇到同样的错误，这里是我的查询“SELECT alumni.[ID NO], alumni.[LAST NAME], alumni.[GIVEN NAME_MI], alumni.[COURSE], courses .[CollegeID], office365alumni.[EmailAddress], office365alumni.[ContactNumber] FROM alumni LEFT JOIN courses ON alumni.[COURSE] = courses.[ID] LEFT JOIN office365alumni ON alumni.[ID NO] = office365alumni.[IDNumber] WHERE校友。[ID NO] = @IDNumber"
我已经编辑了查询，现在试试。如果有多个加入访问，则需要括号。
