在 sql 数据透视表中分组总计

Question

我正在尝试在此数据透视表中创建组总计

            create table test5(city nvarchar(10), race nvarchar(30), sex nvarchar(10), age int)
            insert into test5 values ('Austin',  'African-American', 'male', 21)
            insert into test5 values ('Austin',  'Asian', 'female', 22)
            insert into test5 values ('Austin',  'Caucasian', 'male', 23)
            insert into test5 values ('Austin',  'Hispanic', 'female', 24)
            insert into test5 values ('Austin',  'African-American', 'Unknown', 25)
            insert into test5 values ('Austin',  'Asian', 'male', 26)
            insert into test5 values ('Austin',  'Caucasian', 'female', 27)
            insert into test5 values ('Austin',  'Hispanic', 'Unknown', 28)
            insert into test5 values ('Austin',  'Asian', 'male', 29)
            insert into test5 values ('Austin',  'Caucasian', 'female', 31)
            insert into test5 values ('Dallas',  'Hispanic', 'Unknown', 32)
            insert into test5 values ('Dallas',  'African-American', 'male', 33)
            insert into test5 values ('Dallas',  'Asian', 'female', 34)
            insert into test5 values ('Dallas',  'Caucasian', 'Unknown', 35)
            insert into test5 values ('Dallas',  'Hispanic', 'male', 500)
            insert into test5 values ('Dallas',  'African-American', 'female', 36)
            insert into test5 values ('Dallas',  'Asian', 'Unknown', 37)
            insert into test5 values ('Dallas',  'Caucasian', 'male', 38)
            insert into test5 values ('Dallas',  'Hispanic', 'female', 39)
            insert into test5 values ('Dallas',  'African-American', 'Unknown', 41)
            insert into test5 values ('Houston',  'Asian', 'male', 42)
            insert into test5 values ('Houston',  'Caucasian', 'female', 43)
            insert into test5 values ('Houston',  'Hispanic', 'Unknown', 44)
            insert into test5 values ('Houston',  'African-American', 'male', 45)
            insert into test5 values ('Houston',  'Asian', 'female', 46)
            insert into test5 values ('Houston',  'Caucasian', 'Unknown', 47)
            insert into test5 values ('Houston',  'Hispanic', 'male', 48)
            insert into test5 values ('Houston',  'African-American', 'female', 49)
            insert into test5 values ('Houston',  'Asian', 'Unknown', 51)
            insert into test5 values ('Houston',  'Caucasian', 'male', 52);


    WITH T AS (
        SELECT 
               A.city, A.sex, 
               CASE
                    WHEN A.age BETWEEN 20 AND 30 THEN '20-30_' + race
                    WHEN A.age BETWEEN 31 AND 40 THEN '31-40_' + race
                    WHEN A.age BETWEEN 41 AND 50 THEN '41-50_' + race
               END AS age_range_race
        FROM test5 AS A
    )
    SELECT  *
    FROM T
    PIVOT( COUNT(age_range_race) FOR age_range_race
           IN(
              [20-30_African-American], 
              [20-30_Asian], 
              [20-30_Caucasian], 
              [20-30_Hispanic],
              [31-40_African-American], 
              [31-40_Asian], 
              [31-40_Caucasian], 
              [31-40_Hispanic],
              [41-50_African-American], 
              [41-50_Asian], 
              [41-50_Caucasian], 
              [41-50_Hispanic]
              )
    ) AS P
    ORDER BY city, sex

我需要将它们设置为这样的格式，并在顶部显示组总数。

我将把枢轴放在一个 radgrid 中，所以如果有办法在网格中或使用 C# 来做，那也很好。任何建议都会有所帮助，因为我基本上正在寻找任何方法来实现这一点。提前致谢

您可以尝试使用类似这样的查询：

select city, sex,
count(case when race = 'African-American' and age between 20 and 30 then 1 else null end) as [20_30_African-American],
count(case when race = 'Asian' and age between 20 and 30 then 1 else null end) as [20_30_Asian],
count(case when race = 'Caucasian' and age between 20 and 30 then 1 else null end) as [20_30_Caucasian],
count(case when race = 'Hispanic' and age between 20 and 30 then 1 else null end) as [20_30_Hispanic]
-- add all other columns here
from test5
group by city, sex WITH ROLLUP
order by city, sex
