sql表值函数中实现类似split功能

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

create FUNCTION [dbo].[Fun_split_string](
@s   varchar(2000),   --待分拆的字符串
@split varchar(10)     --数据分隔符
)RETURNS @re TABLE(col varchar(100))
AS
BEGIN
DECLARE @splitlen int
SET @splitlen=LEN(@split+'a')-2
WHILE CHARINDEX(@split,@s)>0
BEGIN
INSERT @re VALUES(LEFT(@s,CHARINDEX(@split,@s)-1))
SET @s=STUFF(@s,1,CHARINDEX(@split,@s)+@splitlen,'')
END
INSERT @re VALUES(@s)
RETURN
END

--Test
select * from [Fun_split_string]('102,103,105,106,107,108,200,500,306,408',',')
