SQL Select Into #Temp

Question

我有一个复杂的SQL查询可以工作。这就像

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 

它做我想做的事情。但是，当我把它包在

SELECT * INTO #Temp FROM() 

我得到一个不正确的语法附近“）”。

我很困惑。我只是想将结果放入临时表中，以便我可以对其进行进一步处理。为什么它不起作用？

您错过了子查询的别名。

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

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
