【问题描述】：

我有一个有效的复杂 SQL 查询。好像

    SELECT * FROM Site s
    JOIN (
        SELECT DISTINCT z.Value FROM Doc z
        JOIN (
            SELECT x.DocumentID FROM Doc x
            JOIN (
                SELECT DocumentID, MAX(VERSION) AS VERSION 
                FROM Doc GROUP BY DocumentID) y ON y.DocumentID = x.DocumentID
            WHERE DocumentTypeID = 78 AND MetadataTypeID = 22 AND VALUE > GETDATE() AND y.Version = x.Version
            ) a ON z.DocumentID = a.DocumentID
        WHERE MetadataTypeID = 2
    ) b ON b.Value = s.SiteID
    WHERE SiteID > 0

它做我想做的事。但是当我把它包装在

SELECT * INTO #Temp FROM ()

我在 ')' 附近得到一个不正确的语法。

我很困惑。我只是想把结果放到一个临时表中，这样我就可以做进一步的工作了。为什么它不起作用？

【问题讨论】：

使用别名SELECT * INTO #Temp FROM () AS A
试试SELECT * INTO #Temp FROM () AS a
不错。感谢你们的快速回答。

您缺少子查询的别名。

SELECT * INTO #MyTempTable
FROM
(
SELECT * FROM Site s
    JOIN (
        SELECT DISTINCT z.Value FROM Doc z
        JOIN (
            SELECT x.DocumentID FROM Doc x
            JOIN (
                SELECT DocumentID, MAX(VERSION) AS VERSION 
                FROM Doc GROUP BY DocumentID) y ON y.DocumentID = x.DocumentID
            WHERE DocumentTypeID = 78 AND MetadataTypeID = 22 AND VALUE > GETDATE() AND y.Version = x.Version
            ) a ON z.DocumentID = a.DocumentID
        WHERE MetadataTypeID = 2
    ) b ON b.Value = s.SiteID
    WHERE SiteID > 0
) AS DT

                FROM Doc GROUP BY DocumentID) y ON y.DocumentID = x.DocumentID
            WHERE DocumentTypeID = 78 AND MetadataTypeID = 22 AND VALUE > GETDATE() AND y.Version = x.Version
            ) a ON z.DocumentID = a.DocumentID
        WHERE MetadataTypeID = 2
    ) b ON b.Value = s.SiteID
    WHERE SiteID > 0)al
