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

select

(case when Grouping(Class)=1 then '总平均' when Grouping(Student)=1 then '' else Class end ) as Class

,(case when Grouping(Class)=1 then '' when Grouping(Student)=1 then '平均' else Student end) as Student

,avg(语文) as 语文

,avg(数学) as 数学

,avg(英语) as 英语

,avg(总分) as 总分

from (

select Class,Student

,(select isnull(sum(Quantity),0) from @tab where Class=t.Class and Student=t.Student and Course='语文') as '语文'

,(select isnull(sum(Quantity),0) from @tab where Class=t.Class and Student=t.Student and Course='数学') as '数学'

,(select isnull(sum(Quantity),0) from @tab where Class=t.Class and Student=t.Student and Course='英语') as '英语'

,(select isnull(sum(Quantity),0) from @tab where Class=t.Class and Student=t.Student) as '总分'

from @tab as t

group by Class,Student

) as tempTab

group by Class,Student,语文,数学,英语,总分 with rollup

having Grouping(语文)=1

and Grouping(数学)=1

and Grouping(英语)=1
