使用游标写的查询，求改写成一条SQL语句
CREATE   TABLE   [typeTable]   (
[id]   [int]   IDENTITY   (1,   1)   NOT   NULL   ,
[type]   [varchar]   (10)   COLLATE   Chinese_PRC_CI_AS   NOT   NULL   ,
[value]   [int]   NOT   NULL   ,
CONSTRAINT   [PK_typeTable]   PRIMARY   KEY     CLUSTERED  
(
[id]
)     ON   [PRIMARY]  
)   ON   [PRIMARY]
GO

INSERT   INTO   typeTable   VALUES(   'b ',   10);
INSERT   INTO   typeTable   VALUES(   'a ',   10);
INSERT   INTO   typeTable   VALUES(   'b ',   5)
INSERT   INTO   typeTable   VALUES(   'a ',   15)
INSERT   INTO   typeTable   VALUES(   'a ',   10)
INSERT   INTO   typeTable   VALUES(   'a ',   30)
INSERT   INTO   typeTable   VALUES(   'a ',   20)

--------------------
create   table   #tempTable([id]   [int],
[type]   [varchar](10),
[value]   [int])

declare   @type   varchar(20)
declare   Mydec   cursor   for   select     distinct(type)   from   typeTable
open   Mydec

fetch   next   from   Mydec   into   @type
while(@@fetch_status   =   0)
begin

insert   into   #tempTable   select   *   from   typeTable   where   id   in
(select   id   from  
(select   id,type,[sum]=(select   sum([value])from   (select   *   from   typeTable   where   type   =   @type)   C   where   id!> A.id   and   A.type=   @type)
  from   typeTable   A   )   B   where   B.[sum]   !>   30)

fetch   next   from   Mydec   into   @type
end
close   Mydec
deallocate   Mydec

select   *   from   #tempTable
drop   table   #tempTable
---------------------------------------------
drop   table   [typeTable]

求：中间的用一条SQL语句实现。。
实现功能：   查出每个type的value之和不大于30的记录
结果：
id         type     value
2             a         10
4             a         15
1             b         10
3             b         5

不知道我表达的大家能不能看懂！
