求sql查询语句（转换数据表由纵向转换成横向)

 

我的表结构：   
  ID(主键)     studentNo   courseNo   score   
  1                     01                 2001         99   
  2                     01                 2002         98   
  3                     01                 2003         97   
  4                     02                 2001         95   
  5                     02                 2002         94   
  6                     02                 2003         93   
-----------------------------------------------
  查询结果   
  studentNo     2001           2002           2003   
  01                       99               98               97   
  02                       95               94               93 
declare   @s   varchar(8000)   
  set   @s=@s+',['+cast(courseNo   as   varchar)+']=sum(case   courseNo   when   '''+cast(courseNo   as   varchar)+'''   then   score   end)'   
  from   表   
  group   by   courseNo   
  exec('select   studentNo'+@s+'   from   表   group   by   studentNo')
