Sql 左连接，两个表不工作

我试图在MS ACCESS2010查询中连接两个表，但它给出了一个错误 这是一个问题

SELECT f.FileName, f.CreationDate, fs.SheetName, fs.SheetNo, SB.Tags
 FROM Files AS  f  LEFT JOIN FilesSheets AS  fs
ON f.FileId = fs.FileId
LEFT JOIN SubmitSheets AS  SB 
ON  f.FileId =SB.FileId
WHERE f.FileId = 'Machine_Inspection_20140820183554.xlsx'

这里是错误

Access需要在连接周围加括号以对其进行分组。试试这个：

SELECT f.FileName, f.CreationDate, fs.SheetName, fs.SheetNo, SB.Tags
FROM (Files f 
LEFT JOIN FilesSheets fs
ON f.FileId = fs.FileId)
LEFT JOIN SubmitSheets SB 
ON  f.FileId = SB.FileId
WHERE f.FileId = 'Machine_Inspection_20140820183554.xlsx'
