SQL選擇成#Temp

Question

我有一個有效的復雜SQL查詢。 就像是

    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

它完成了我想要的操作。 但是當我把它包起來時

SELECT * INTO #Temp FROM ()

我在'）'附近收到錯誤的語法。

我糊塗了。 我只想將結果放入臨時表中，以便可以對其做進一步的工作。 為什么不起作用？

您缺少子查詢的別名。

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

select * into TBL_name 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)al
