Question

我正在尝试完成下面的查询，但我不断收到错误消息：

“JOIN操作中的语法错误”。

SELECT myExternalTable1.INCIDENT_ID AS INCIDENT_NR, 
First(myExternalTable1.PARENTITEM) AS [COMPANY], 
First(myExternalTable1.LOGGEDDATE) AS [LOGGED_DATE], 
First(myExternalTable1.STATUS) AS [STATUS], 
First(myExternalTable1.PRIORITY) AS [PRIORITY], 
First(myExternalTable1.CATEGORY) AS [COMPLEXITY], 
First(myExternalTable1.USERGROUP) AS [GROUP], 
First(myExternalTable1.SPECIALISTID) AS [SPECIALIST], 
First(myExternalTable1.MODULE) AS [CATEGORY], 
Last(myExternalTable1.ActionDate) AS [ACTIONDATE], 
First(myExternalTable1.Description) AS [DESCRIPTION], 
iif([STATUS]=""Closed"" Or [STATUS]=""Cancelled"" Or [STATUS]=""Resolved"", DateDiff(""d"",LOGGED_DATE,ACTIONDATE), DateDiff(""d"",LOGGED_DATE,Date())) AS [DAYS_OPEN], 
myExternalTable2.responseachieved AS [SLA_STATUS]
FROM ((myExternalTable1 IN 'K:\SOME_FOLDER\SOME_FOLDER\SOMEFOLDER\myExternalDB1.accdb') 
LEFT JOIN (myExternalTable2 IN 'K:\SOME_FOLDER\SOME_FOLDER\SOMEFOLDER\myExternalDB2.accdb') 
ON myExternalTable2.id = myExternalTable1.INCIDENT_ID) 
WHERE (LOGGED_DATE>#12/31/2013#)
GROUP BY INCIDENT_NR 
ORDER BY LOGGED_DATE;

我尝试重命名表和文件路径以保持这些秘密，同时仍保留其中使用的语法。任何帮助将不胜感激。
