Split function by comma in SQL Server 2008

Question

I know that this question has been asked many times but could not find what I needed.

I have this column \"Order\" which contains data in the following format.

I've change the function name so it won't overlapped in what the Split() function really does.

Here is the code:

CREATE FUNCTION dbo.GetColumnValue(
@String varchar(8000),
@Delimiter char(1),
@Column int = 1
)
returns varchar(8000)
as     
begin

declare @idx int     
declare @slice varchar(8000)     

select @idx = 1     
    if len(@String)<1 or @String is null  return null

declare @ColCnt int
    set @ColCnt = 1

while (@idx != 0)
begin     
    set @idx = charindex(@Delimiter,@String)     
    if @idx!=0 begin
        if (@ColCnt = @Column) return left(@String,@idx - 1)        

        set @ColCnt = @ColCnt + 1

    end

    set @String = right(@String,len(@String) - @idx)     
    if len(@String) = 0 break
end 
return @String  
end

And here is the usage:

select dbo.GetColumnValue('Col1,Field2,VAlue3', ',', 3)
