sql自定义函数:SF_Split，根据指定的分割符，把一个字符串分割成若干条短数据

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].SF_Split') and xtype in (N'FN', N'IF', N'TF'))
begin
drop function SF_Split
end
go

调用例子如下：

select * from dbo.[SF_Split]('abc-def-ghi-jkl','-')
select * from dbo.[SF_Split]('共存媒体1,共存媒体2,共存媒体4',',')
*/

create function SF_Split(@SourceSql varchar(8000),@StrSeprate varchar(1))
returns @temp table(Short varchar(500))
--实现split功能 的函数
as
begin
declare @i int
set @SourceSql=rtrim(ltrim(@SourceSql))
set @i=charindex(@StrSeprate,@SourceSql)

while @i>=1
begin
insert @temp values(left(@SourceSql,@i-1))
set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)
set @i=charindex(@StrSeprate,@SourceSql)
end

if @SourceSql<>'\'
insert @temp values(@SourceSql)

return
end
