1、列转行
数据经过计算加工后会直接生成前端图表需要的数据源，但是程序里又需要把该数据经过列转行写入中间表中，下次再查询该数据时直接从中间表查询数据。
1.1 列换行语法
table_source UNPIVOT( value_column FOR pivot_column IN(<column_list>) )
1.2 行转列案例
WITH T
AS
(
SELECT 1 as TeamId,'测试团队1' as Team,80 'MEN',20 'WOMEN'
UNION
SELECT 2 as TeamId,'测试团队2' as Team,30 'MEN',70 'WOMEN'
) ---列转行------------------------------------
SELECT TeamId,Team ,TYPE=ATTRIBUTE,CNT=VALUE
FROM T
UNPIVOT (
VALUE FOR ATTRIBUTE IN ([MEN],[WOMEN])
) AS UPV
2、 行转列
行转列主要是从中间表里查询数据，SQL SERVER2005以下的版本则可以使用聚合函数来完成。
2.1 行转列语法
table_source PIVOT( 聚合函数（value_column） FOR pivot_column IN(<column_list>) )
2.2、使用PIVOT实现
WITH T
AS
(
SELECT 1 AS ID,'测试团队1' TEAM,'MEN' ITEM,80 CENT
UNION
SELECT 1 AS ID,'测试团队1' TEAM,'WOMEN' ITEM,20 CENT
UNION
SELECT 2 AS ID,'测试团队2' TEAM,'MEN' ITEM,30 CENT
UNION
SELECT 2 AS ID,'测试团队2' TEAM,'WOMEN' ITEM,70 CENT
) SELECT * FROM T PIVOT (SUM(CENT) FOR ITEM IN ([MEN],[WOMEN])) A
2.3、使用聚合函数实现
WITH T
AS
(
SELECT 1 AS ID,'测试团队1' TEAM,'MEN' ITEM,80 CENT
UNION
SELECT 1 AS ID,'测试团队1' TEAM,'WOMEN' ITEM,20 CENT
UNION
SELECT 2 AS ID,'测试团队2' TEAM,'MEN' ITEM,30 CENT
UNION
SELECT 2 AS ID,'测试团队2' TEAM,'WOMEN' ITEM,70 CENT
) SELECT ID,TEAM,
SUM(CASE WHEN ITEM='MEN' THEN CENT ELSE 0 END) 'MEN',
SUM(CASE WHEN ITEM='WOMEN' THEN CENT ELSE 0 END) 'WOMEN'
FROM T
GROUP BY ID,TEAM
