Create a temp table from a string list

How would I create a table function that converts an nvarchar(500) string into a temp table?  This routine would take a string of CSV and convert it into a table with each row representing a single value of the list.  All values inputted will be numbers.


I want to access this function inside a stored procedure.

CREATE FUNCTION [dbo].[fn_NumberStringListToTable]
(	
	@IncomingList nvarchar(500)
)
RETURNS @ListTable table 
	( input int)
	
AS
BEGIN
	Declare @Input nvarchar(500), @Position int
	SET @IncomingList = LTRIM(RTRIM(@IncomingList)) + ','
	SET @Position = CHARINDEX(',', @IncomingList, 1)
	
	WHILE @Position > 0
	BEGIN
		SET @Input = LTRIM(RTRIM(LEFT(@IncomingList, @Position -1)))
		IF @Input <> ''
		BEGIN
			INSERT INTO @ListTable (input)
			VALUES (CAST(@Input AS int))
		END
		SET @IncomingList = RIGHT(@IncomingList, LEN(@IncomingList) - @Position)
		SET @Position = CHARINDEX(',', @IncomingList, 1)
	END	
RETURN 
END
