合并列值
原著：邹建
改编：爱新觉罗.毓华  2007-12-16  广东深圳

表结构，数据如下：
id    value
----- ------
1     aa
1     bb
2     aaa
2     bbb
2     ccc

需要得到结果：
id     values
------ -----------
1      aa,bb
2      aaa,bbb,ccc
即：group by id, 求 value 的和（字符串相加）

1. 旧的解决方法(在sql server 2000中只能用函数解决。)
--1. 创建处理函数
create table tb(id int, value varchar(10))
insert into tb values(1, 'aa')
insert into tb values(1, 'bb')
insert into tb values(2, 'aaa')
insert into tb values(2, 'bbb')
insert into tb values(2, 'ccc')
go

CREATE FUNCTION dbo.f_str(@id int)
RETURNS varchar(8000)
AS
BEGIN
    DECLARE @r varchar(8000)
    SET @r = ''
    SELECT @r = @r + ',' + value FROM tb WHERE id=@id
    RETURN STUFF(@r, 1, 1, '')
END
GO

-- 调用函数
SELECt id, value = dbo.f_str(id) FROM tb GROUP BY id

drop table tb
drop function dbo.f_str

/*
id          value      
----------- -----------
1           aa,bb
2           aaa,bbb,ccc
（所影响的行数为 2 行）
*/

--2、另外一种函数.
create table tb(id int, value varchar(10))
insert into tb values(1, 'aa')
insert into tb values(1, 'bb')
insert into tb values(2, 'aaa')
insert into tb values(2, 'bbb')
insert into tb values(2, 'ccc')
go

--创建一个合并的函数
create function f_hb(@id int)
returns varchar(8000)
as
begin
  declare @str varchar(8000)
  set @str = ''
  select @str = @str + ',' + cast(value as varchar) from tb where id = @id
  set @str = right(@str , len(@str) - 1)
  return(@str)
End
go

--调用自定义函数得到结果：
select distinct id ,dbo.f_hb(id) as value from tb

drop table tb
drop function dbo.f_hb

/*
id          value      
----------- -----------
1           aa,bb
2           aaa,bbb,ccc
（所影响的行数为 2 行）
*/

2. 新的解决方法(在sql server 2005中用OUTER APPLY等解决。)
create table tb(id int, value varchar(10))
insert into tb values(1, 'aa')
insert into tb values(1, 'bb')
insert into tb values(2, 'aaa')
insert into tb values(2, 'bbb')
insert into tb values(2, 'ccc')
go
-- 查询处理
SELECT * FROM(SELECT DISTINCT id FROM tb)A OUTER APPLY(
        SELECT [values]= STUFF(REPLACE(REPLACE(
            (
                SELECT value FROM tb N
                WHERE id = A.id
                FOR XML AUTO
            ), '<N value="', ','), '"/>', ''), 1, 1, '')
)N
drop table tb

/*
id          values
----------- -----------
1           aa,bb
2           aaa,bbb,ccc

(2 行受影响)

没错写个函数就行

create function f_hb(@FACTORY_NAME varchar(10) , @STOP_THING varchar(10))
returns varchar(8000)
as
begin
declare @str varchar(8000)
set @str = ''

set @str = right(@str , len(@str) - 1)
return(@str)
End

謝謝大家，昨天就搞定，忘了結帖。

--这个可以用一个函数实现:
--首先写一个返回MOB_PHONE 的函数如下

Create FUNCTION [dbo].[F_getValue] 
(
@FACTORY_NAME nvarchar(50),
@STOP_THING nvarchar(20)
)
RETURNS nvarchar(max)
AS
begin
   declare @strRet nvarchar(max)
   set @strRet = ''
    select @strRet = @strRet+MOB_PHONE+',' from t_test 
   where FACTORY_NAME= @FACTORY_NAME and STOP_THING=@STOP_THING
  return @strRet
end

-- 测试数据
--select distinct a.FACTORY_NAME,a.STOP_THING,dbo.F_getValue(a.FACTORY_NAME,a.STOP_THING) as 

--MOB_PHONE from t_test a  -- 这个的后面有一个逗号,

select distinct a.FACTORY_NAME,a.STOP_THING,substring(dbo.F_getValue(a.FACTORY_NAME,a.STOP_THING),0,len(dbo.F_getValue(a.FACTORY_NAME,a.STOP_THING))-1) as MOB_PHONE from t_test a


--测试结果
   FACTORY_NAME  STOP_THING       MOB_PHONE
