合并列值：

--> 数据库版本:

--> Microsoft SQL Server 2008 (RTM) - 10.0.1600.22

--> 测试数据：[TB]

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[TB]') 

AND type in (N'U')) 

DROP TABLE [TB]

GO



---->建表

create table [TB]([name] varchar(4),[status] varchar(8))

insert [TB]

select '小张','普通员工' union all

select '小张','组长' union all

select '小二','经理' union all

select '小三','老板' union all

select '小三','员工'

GO



方法一：

SELECT a.name,

status =stuff((

select ','+convert(varchar(20),status) FROM [TB] WHERE name = a.name  for xml path(''))

,1,1,'')

FROM [TB] a 

group by a.name



方法二：

SELECT   a.name,

status =STUFF(REPLACE(REPLACE(

(select status

FROM [TB]  

where name = a.name  

FOR XML AUTO

), '<TB status="', ','), '"/>', ''), 1, 1, '') 

FROM [TB] a 

group by a.name  

--> 查询结果

SELECT * FROM [TB]

--> 删除表格

--DROP TABLE [TB]

SQL SERVER 2000用函数处理



---->建表

create table [TB](date1 varchar(10),time1 varchar(5))

insert [TB]

select '2010-10-20','12:00' union all

select '2010-10-20','13:00' union all

select '2010-10-21','14:00' union all

select '2010-10-21','15:00' union all

select '2010-10-20','16:00'

GO





CREATE function dbo.fn_date(@date1 as varchar(50))

returns varchar(1000)

as   

begin

declare @s varchar(1000)

set @s=''

select @s=@s+isnull(time1,'')+';'

from A where date1=@date1

return (@s)

end





select date1,dbo.fn_date(date1) as time1

from A

group by date1
