在数据库中使用表值函数分割字符串

Create function [dbo].[f_split](@SourceSql varchar(8000),@StrSeprate varchar(10))
returns @temp table(a varchar(100))

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

select * from f_split('1,2,3',',')
