效果如图所示:

测试sql语句如下:

复制代码 代码如下:

declare @tab table(Class varchar(20),Student varchar(20),Course varchar(50),Quantity decimal(7,2));

insert into @tab(Class,Student,Course,Quantity) values('A班','张三','语文',60);

insert into @tab(Class,Student,Course,Quantity) values('A班','张三','数学',70);

insert into @tab(Class,Student,Course,Quantity) values('A班','张三','英语',80);

insert into @tab(Class,Student,Course,Quantity) values('A班','李四','语文',30);

insert into @tab(Class,Student,Course,Quantity) values('A班','李四','数学',40);

insert into @tab(Class,Student,Course,Quantity) values('A班','李四','英语',50);

insert into @tab(Class,Student,Course,Quantity) values('B班','王五','语文',65);

insert into @tab(Class,Student,Course,Quantity) values('B班','王五','数学',75);

insert into @tab(Class,Student,Course,Quantity) values('B班','王五','英语',85);

insert into @tab(Class,Student,Course,Quantity) values('B班','赵六','语文',35);

insert into @tab(Class,Student,Course,Quantity) values('B班','赵六','数学',45);

insert into @tab(Class,Student,Course,Quantity) values('B班','赵六','英语',55);

select * from @tab
