借助用户定义函数：
---------------------------------------------------------------------
--生成测试数据
create table 表(部门 int,人员 varchar(20))
insert into 表 select 1,'张三'
insert into 表 select 1,'李四'
insert into 表 select 1,'王五'
insert into 表 select 2,'赵六'
insert into 表 select 2,'邓七'
insert into 表 select 2,'刘八'
go

--创建用户定义函数
create function f_str(@department int)
returns varchar(8000)
as
begin
declare @ret varchar(8000)
set @ret = ''
select @ret = @ret+','+人员 from 表 where 部门 = @department
set @ret = stuff(@ret,1,1,'')
return @ret
end
go


--执行
select 部门,人员=dbo.f_str(部门) from 表 group by 部门 order by 部门
go

--输出结果
/*
部门 人员
---- --------------
1 张三,李四,王五
2 赵六,邓七,刘八
*/


--删除测试数据
drop function f_str
drop table 表
go



--楼主,你说的是这种吗?
