能用一句SQL实现吗？
我现在有个商品序列号表；
商品编号(PROID)、商品序列号(PROSN)
10 10001
10 10002
10 10003
想用一句SQL得到(10001，10002，10003)这样的结果可以吗？
[解决办法]
CREATE TABLE feng (proid int,prosn varchar(50))
GO
INSERT feng VALUES (10,1001),(10,1002),(10,1003)
GO
SELECT
LEFT(REPLACE(REPLACE(CAST((SELECT prosn FROM feng FOR XML AUTO)AS VARCHAR(4000)),'<feng prosn="',''),'"/>',',')
,LEN(REPLACE(REPLACE(CAST((SELECT prosn FROM feng FOR XML AUTO)AS VARCHAR(4000)),'<feng prosn="',''),'"/>',','))-1)

--> 测试数据：[huang]
if object_id('[huang]') is not null drop table [huang]
go
create table [huang]([PROID] int,[PROSN] int)
insert [huang]
select 10,10001 union all
select 10,10002 union all
select 10,10003
--------------开始查询--------------------------
if object_id('F_Str') is not null
drop function F_Str
go
create function F_Str(@Col1 int)
returns nvarchar(100)
as
begin
declare @S nvarchar(100)
select @S=isnull(@S+',','')+CAST([PROSN] AS VARCHAR) from [huang] where [PROID]=@Col1
return @S
end
go
Select distinct [PROID],PROSN=dbo.F_Str([PROID]) from [huang]
----------------结果----------------------------
/*
PROID PROSN

10 10001,10002,10003
