我的加入有什么问题？

Question

我有以下程序，JOIN没有工作：

CREATE PROCEDURE afficherConsomVspVM 
     (@start DATE, @end DATE, @lun NVARCHAR (250), @splitLun NVARCHAR (250) )
AS
   SET NOCOUNT ON

   CREATE TABLE dbo.#temp (dateCollecte DATE, lun NVARCHAR (250), VMUsed FLOAT)

   INSERT INTO dbo.#temp (dateCollecte, lun, VMUsed)
      (SELECT dateCollecte, lun = @lun, VMUsed = (capacity - freeSpace)/1024
       FROM dbo.VmwareDatastore
       WHERE dateCollecte BETWEEN @start AND @end 
         AND lun LIKE '________________________________________' + @splitLun

       UNION

       SELECT dateCollecte, lun = @lun, VMUsed = usedSpace
       FROM dbo.SunZpool
       WHERE dateCollecte BETWEEN @start AND @end 
         AND id IN (SELECT lunId
                    FROM dbo.SunZpool_Luns
                    WHERE name LIKE '_____________________________' + @splitLun + '%'))

    SELECT 
        t1.dateCollecte, 
        VspUsed = MAX(t1.consumedCapacityInKB), 
        total = MAX(t1.capacityInKB)
    FROM 
        dbo.Vsp t1
    FULL JOIN 
        dbo.#temp t2 ON t1.dateCollecte = t2.dateCollecte
    WHERE 
        t1.dateCollecte BETWEEN @start AND @end 
        AND displayName = @lun
    GROUP BY 
        t1.dateCollecte

    DROP TABLE dbo.#temp
    SET NOCOUNT OFF 

我知道在临时表#temp中正确插入了值（我已经测试了该部分代码并且它有效）。在调用该过程时，我只得到最后一个SELECT，好像#temp是空的（它不是）。

为什么JOIN声明不起作用？

仅供参考，我也尝试了LEFT，RIGHT，FULL OUTER和OUTER JOIN。
