Question

我想使用age，account和age group在Reporting Services中创建一个简单的摘要报告，如下所示：

SELECT AGE,COUNT(ACCOUNT)AS TOTALCASES, 
       'AGEGRP' =CASE WHEN AGE <=5 THEN 'AGE 0 TO 5'
                      WHEN AGE >=6 THEN 'AGE 6 AND OLDER'
                 END
FROM MAIN 
GROUP BY 'AGEGRP'

当我在SQL Server Management Studio中运行时，收到错误消息：

Msg 164, Level 15, State 1, Line 1 Each GROUP BY expression must contain 
at least one column that is not an outer reference.

有人可以建议一种方法来生成汇总数据，计算帐号，按age 0 to 5和age 6 and older汇总吗？

Answer 1

如果按AGEGRP分组

，则选择列表中不能包含“年龄”

尝试：

DECLARE @YourTable table (age int, account int)
insert into @YourTable values (1,40)
insert into @YourTable values (2,40)
insert into @YourTable values (3,40)
insert into @YourTable values (4,40)
insert into @YourTable values (5,40)
insert into @YourTable values (6,40)
insert into @YourTable values (7,40)
insert into @YourTable values (8,40)

SELECT
    COUNT(ACCOUNT)AS TOTALCASES, AGEGRP
    FROM (SELECT
              AGE,ACCOUNT, CASE
                               WHEN AGE <=5 THEN 'AGE 0 TO 5'
                               WHEN AGE >=6 THEN 'AGE 6 AND OLDER'
                           END AS AGEGRP
              FROM @YourTable 
         )dt
    GROUP BY AGEGRP

输出：

TOTALCASES  AGEGRP
----------- ---------------
5           AGE 0 TO 5
3           AGE 6 AND OLDER

(2 row(s) affected)

Answer 2

您可以执行内部查询，例如KM显示，也可以重复您想要分组的表达式：

SELECT 
  AGE,
  COUNT(ACCOUNT) AS TOTALCASES, 
  CASE 
    WHEN AGE <=5 THEN 'AGE 0 TO 5'
    ELSE 'AGE 6 AND OLDER'
  END AS AGEGRP
FROM 
  MAIN 
GROUP BY 
  CASE 
    WHEN AGE <=5 THEN 'AGE 0 TO 5'
    ELSE 'AGE 6 AND OLDER'
  END

Answer 3

在最终结果集中不可能有AGE。我觉得你在一起混合两个请求。采用KM的解决方案，您可以获得内部结果，也可以获得没有AGE列的外部结果。

编辑：KM刚刚编辑了他的回复，我也是:) :)无论如何，我引用了以下两个结果：

从年龄组选择年龄，（案例...结束）作为年龄组
选择年龄组，计数（*）作为案例（选择年龄，（案例......结束）作为年龄组）t group by agegroup

使用T-SQL案例声明汇总报告数据
