使用unpivot实现列转行

create table Fruit(id int,name varchar(20), Q1 int, Q2 int, Q3 int, Q4 int);

insert into Fruit values(1,'苹果',1000,2000,3300,5000);
insert into Fruit values(2,'橘子',3000,3000,3200,1500);
insert into Fruit values(3,'香蕉',2500,3500,2200,2500);
insert into Fruit values(4,'葡萄',1500,2500,1200,3500);
select * from Fruit;

-- 列转行
select id, name, jidu, xiaoshou from Fruit unpivot (xiaoshou for jidu in (q1, q2, q3, q4));
