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

Question

我希望这个查询告诉我 2013 年支出前 10 名的公司在 2012 年的支出！

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，我没有收到任何错误，但 Access 说它正在“运行查询”并且永远不会完成。数据的大小不是问题。

这是我找到的最接近的例子，但它并没有真正说明答案：MS Access - WHERE IN works, but WHERE NOT IN fails

我怀疑这只是 Access 优化器的一个限制。试试这样吧：

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
