SQL语句实现横排？
有一个表：
BH            GZLB          JE
----------------------
001            A              100
001            B              150
001            C              110
002            A              99
002            B              180
002            C              150
003            A              160
003            B              170
003            C              130
用SQL语句如何将上面的表变成下面横向的排列方式呢。
BH        A      B      C
-------------------
001    100    150  110
002    99      180  150
003    160    170  130
（GZLB  里面的字段是动态的，不是只有A,B,C  可能还有A,B,C,D,E...）

---------------------------------------------------------------

if  exists(select  name  from  sysobjects  where  name='tblA'  and  xtype='U')
     drop  table  tblA

create  table  tblA(
   BH  char(3)  not  null,
   GZLB  varchar(3)  not  null,
   JE  int  not  null
)
go

insert  tblA  values('001',            'A',              100)
insert  tblA  values('001',            'B',              150)
insert  tblA  values('001',            'C',              110)
insert  tblA  values('002',            'A',              99)
insert  tblA  values('002',            'B',              180)
insert  tblA  values('002',            'C',              150)
insert  tblA  values('003',            'A',              160)
insert  tblA  values('003',            'B',              170)
insert  tblA  values('003',            'C',              130)

   declare  @sql  varchar(600)
   set  @sql  =  'select'
   select  distinct  GZLB  as  'GZLB'  into  tmp  from  tblA


   select  @sql  =  @sql  +'  max(case  GZLB  when  '''+  GZLB  +'''  then  JE  else  null  end)  as  '''+  GZLB  +''','  from  tmp
   set  @sql  =  substring(@sql,  1,  len(@sql)-1)  +'  from  tblA  group  by  BH'
   exec(@sql)
---------------------------------------------------------------

用游标
declare  @sqlstr  varchar(2000)
declare  @gzlb
select  sqlstr='select  bh'
declare  cgzlb  cursor  for  select  gzlb  from  table
create  table  #a
(bh  char(3))
open  cgzlb
fetch  next  from  cgzlb  into  @gzlb
while  (fetch_status<>-1)
begin
exec('alter  table  #a  add  '+@gzlb  +'  char(1)')
exec('insert  into  #a  (bh,'+@gzlb+'    select  bh,je  from  table  where  gzlb='''+@gzlb+'''')
select  @sqlstr=@sqlstr+',sum(isnull('+@gzlb+'))'

fetch  next  from  cgzlb  into  @gzlb
end
close  cgzlb
deallocate  cgzlb
select  @sqlstr=@sqlstr+'  from  #a  group  by  bh  order  by  bh
execute(@sqlstr)

---------------------------------------------------------------

declare  @sql  varchar(6000)
   set  @sql  =  'select  '
   select  @sql  =  @sql  +'  sum(case  GZLB  when  '''+  GZLB  +'''  then  JE  else  null  end)  ['+  GZLB  +'],'  from  (select  distinct  GZLB  as  GZLB    from  tblA)  tmp
   set  @sql  =  substring(@sql,  1,  len(@sql)-1)  +'  from  tblA  group  by  BH'
   exec(@sql)
