 drop table dbo.score
go
create table dbo.score(stuid char(10) not null,sid int not null,
score int not null,
constraint pk_score(stuid,sid));

insert into subject(sname) values('语文');
insert into subject(sname) values('数学');
insert into subject(sname) values('英语');

DECLARE @strSQL VARCHAR(8000)

SET @strSQL = 'SELECT t.STUNAME [姓名]'

SELECT @strSQL = @strSQL + ',SUM(CASE s.SNAME WHEN ''' + SNAME + ''' THEN g.[Score] END) [' + SNAME + ']'
FROM (SELECT SNAME FROM [Subject]) AS tmp

SELECT @strSQL = @strSQL + ' FROM [Score] g,[Subject] s, [Student] t WHERE g.SID=s.SID AND g.STUID = t.STUID  GROUP BY t.STUID, t.STUNAME'

declare @strsql  varchar(100)
