ACCESS 2010 SQL--在SELECT TOP子查询字段上使用WHERE IN

Question

我希望这个查询能告诉我2013年支出前十的公司2012年的支出情况！

SELECT [Company], 
       Sum([SPENDING])
FROM   [Data]
WHERE  [Company] IN (
                     SELECT TOP 10 [Company]
                     FROM          [Data]
                     WHERE         [Year] IN ("2013")
                     GROUP BY      Company
                     ORDER BY      Sum([SPENDING]) DESC
                     )
       AND [Year] IN ("2012")
GROUP BY Company
;

当我尝试运行它时，我没有得到任何错误，但Access说它是"运行查询"，永远不会完成。数据的大小不是问题所在。

这是我发现的最接近的例子，但它并没有真正给出答案：MS Access-WHERE IN有效，但WHERE NOT IN失败

我怀疑这只是Access优化器的一个限制。不如这样试试：

SELECT d.[Company], 
       Sum(d.[SPENDING])
FROM   [Data] As d
INNER JOIN    (
                     SELECT TOP 10 [Company]
                     FROM          [Data]
                     WHERE         [Year] IN ("2013")
                     GROUP BY      Company
                     ORDER BY      Sum([SPENDING]) DESC
              ) As t  ON  t.Company = d.Company
WHERE d.[Year] IN ("2012")
GROUP BY d.Company
