我想将 sql 输出转换为以下格式。这是我的桌子。
Id Country Code Totalcount
1 India 20 120
2 India 21 121
3 India 22 122
4 India 23 123
5 India 24 124
6 US 20 220
7 US 21 221
8 Us 22 222
9 UK 23 323
10 UK 24 324
Select Country, 20,21,22,23,24,25
from
(
Select Country,StatusCode,Totalcount from StatusDetails
) as SourceTable
Pivot
(
sum(Totalcount) for StatusCode in (20,21,22,23,24,25)
) as PivotTable
需要输出如下 one.Do 我需要应用数据透视表。
Country 20 21 22 23 24
India 120 121 122 123 124
US 220 221 222
UK 323 324
为此，我是条件聚合的粉丝：
select country,
max(case when code = 20 then totalcount end) as cnt_20,
max(case when code = 21 then totalcount end) as cnt_21,
max(case when code = 22 then totalcount end) as cnt_22,
max(case when code = 23 then totalcount end) as cnt_23,
max(case when code = 24 then totalcount end) as cnt_24
from sourcetable
group by country
