访问中的汇总和多维数据集运算符（摘要查询）

Question

Access中的Rollup和Cube运算符是否有任何等价物？如果没有，我如何在Access中编写小计和总计（摘要数据）查询？

我写道：

SELECT a,b FROM dumy
UNION ALL select a,sum(b) from dumy
group by a ;

输出类似于下图，或类似的内容，

但预期结果如下：

Answer 1

您可以使用Crosstab次查询。这将产生一行：

TRANSFORM Count(b.ID) AS [Count]
SELECT "BASE" AS SomeName, Count(b.ID) AS Total
FROM ATable AS b
WHERE Something='Text'
GROUP BY "BASE"
PIVOT AFieldName;

Answer 2

只需要排序。

Select T.Total
  , T.a
  , T.b
From (
   SELECT '' as Label
     , a 
     ,b 
   FROM dumy 
   UNION ALL 
  select 'Total' as Label
    , a
    ,sum(b) 
  from dumy 
  group by a 
) as T
Order By T.a, T.Total;
