Answer 1

CREATE function udf_splitstring
(
@str varchar(8000) --要分拆的字符串
,@spli varchar(10) --字符串分隔符
)
returns @retab table(istr varchar(8000))
as
begin
declare @i     int
declare @splen int
select @splen=len(@spli),@i=charindex(@spli,@str)
while @i > 0
begin
insert into @retab 
values(left(@str,@i-1))
select @str=substring(@str,@i+@splen,8000)
select @i=charindex(@spli,@str)
end
if @str<>'' insert into @retab values(@str)
return
end
GOselect istr 
from udf_splitstring('''B01-09-03'',''10003-02-01'',''1-1-3'',''A02-02-01'',''A02-02-02'',''1-1-4''',',')
order by left(istr,charindex('-',istr)-1)

Answer 2

--结果
