我在下面的查询中收到错误。我不确定为什么。
下面的查询是动态sql，它被设置为变量并打印出来。
错误消息：
第150行，第15行，第1行，第60行 关键字“AS”附近的语法不正确。 消息156，第15级，状态1，第77行 关键字“AS”附近的语法不正确。 消息156，第15级，状态1，第86行 关键字“AS”附近的语法不正确。

如果我删除了这部分查询：

ON MAXDATETBL.MDID2 = TBLRevs.R_Document_ID
它运行得很好。我在这里做错了什么？

你有一个额外的支架（在INNER JOIN之后，松开它并尝试
INNER JOIN
(SELECT Document_ID AS MDID2, MAX(REV_DATE) AS MAXREVDATE
FROM tblSDDocuments_REV
GROUP BY Document_ID) AS MAX1
INNER JOIN tblSDDocuments_REV R1 ON MAX1.MAXREVDATE = R1.Rev_Date AND MAX1.MDID2 = R1.Document_ID) AS MAXDATETBL
ON MAXDATETBL.MDID2 = TBLRevs.R_Document_ID
答案 1 :(得分：0)
问题 与此片段：
INNER JOIN ((SELECT Document_ID AS MDID2, MAX(REV_DATE) AS MAXREVDATE
FROM tblSDDocuments_REV
GROUP BY Document_ID) AS MAX1
INNER JOIN tblSDDocuments_REV R1
ON MAX1.MAXREVDATE = R1.Rev_Date AND MAX1.MDID2 = R1.Document_ID) AS MAXDATETBL
ON MAXDATETBL.MDID2 = TBLRevs.R_Document_ID
问题是为连接的结果分配别名（MAXDATETBL）。显然SQL Server不喜欢这样，实际上你不需要那个别名。该内部内部联接的结果集中的列应该使用有助于连接的表的别名来引用。也就是说，您应该指定MAXDATETBL.MDID2：
MAX1.MDID2
INNER JOIN ((SELECT Document_ID AS MDID2, MAX(REV_DATE) AS MAXREVDATE
FROM tblSDDocuments_REV
GROUP BY Document_ID) AS MAX1
INNER JOIN tblSDDocuments_REV R1
ON MAX1.MAXREVDATE = R1.Rev_Date AND MAX1.MDID2 = R1.Document_ID) AS MAXDATETBL
ON MAX1.MDID2 = TBLRevs.R_Document_ID
您甚至可以省略内部联接的括号。它们是允许的但是是多余的，因为语法清楚地表明片段开头的INNER JOIN的右侧实际上是MAX1和R1之间的连接，而不是{{1}单独。
