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‘,‘,‘)
