CREATE FUNCTION [dbo].[fnGetIDasTable] (
    @ids varchar(MAX), 
    @separator varchar(20)
) RETURNS @retTable TABLE(ID bigint)
BEGIN
    DECLARE @firstComma bigint
    IF (@ids IS NOT NULL)
    BEGIN
        WHILE @ids != ''
        BEGIN
            SET @firstComma = CHARINDEX(@separator, @ids)
            IF @firstComma = 0
            BEGIN
                INSERT INTO @retTable 
                    VALUES (@ids)
                RETURN
            END
            INSERT INTO @retTable 
                VALUES (CONVERT(bigint, SUBSTRING(@ids, 1, @firstComma - 1)))
            SET @ids = SUBSTRING(@ids, @firstComma + 1, LEN(@ids))
        END
    END
    RETURN
END

DECLARE @IdList varchar(MAX) = '1,3'
SELECT id FROM Table1 
    INNER JOIN [dbo].[fnGetIDasTable] (@IdList,',') il ON Table1.id = il.ID
