我在下面的查询中遇到错误。我不确定为什么。

下面的查询是动态sql，设置成变量并打印出来。

错误消息：

消息 156，级别 15，状态 1，第 60 行关键字“AS”附近的语法不正确。消息 156，级别 15，状态 1，第 77 行关键字“AS”附近的语法不正确。消息 156，级别 15，状态 1，第 86 行关键字“AS”附近的语法不正确。

                    ORDER BY    DocumentNo ,TBLRevs.R_Document_ID, TBLRevs.R_DocumentRev_ID DESC

如果我删除这部分查询：

             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

它运行良好。知道我在这里做错了什么吗？

问题在于这个片段：

 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

问题是将别名 ( MAXDATETBL) 分配给连接的结果。显然 SQL Server 不喜欢这样，实际上你也不需要那个别名。该内部内部联接的结果集中的列应该使用有助于联接的表的别名来引用。也就是说，MAXDATETBL.MDID2您应该指定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连接周围的括号。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 的右侧实际上是一个连接MAX1，R1而不是MAX单独连接。

你有一个额外的支架（就在 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
