How to separate string into x strings separated by #

Question

Hi there
I have the following
drop table metteordrer2;
create table metteorder2 as
select
    '#p1,1525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525,1863,1943,1960,2030,2042,2046,2047,#p2,1525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525,#p3,4,5,6' produkter
    from dual
;The output should be:
ID     PRODUCTS
P1    1525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525,1863,1943,1960,2030,2042,2046,2047
p2    1525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525
p3    p3,4,5,6I need to solve it using recursive subf. since the code should be converted to SS2008 (and this does not support connnect by).
Could you assist me?

Hello again.
I just needed a piece of quiteness at home .... then I got what I needed ... nothing like a warm meal and som quiteness :-)
This is a working solution in an 11.2 g environment - ready for minor ajustments for SS2008 (just change substr and instr function calls):
I have made a couple of change in var names, since the now reflect real names, ready to be put infront of a larger query.
drop table metteordrer2;
create table metteordrer2 as
select
    '#p1,1525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525,1863,1943,1960,2030,2042,2046,2047,#p2,2525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525,1863,1943,1960,2030,2042,2046,2047,#p3,4,5,6,#p100,1' alle_linier
    from dual
select * from metteordrer2;
WITH   
----- split input op i id, og de efterflg. "rækker
alle_linier (id, linie, tilbage_linier)    AS
SELECT  SUBSTR (alle_linier , 2, INSTR ( alle_linier  || ',' , ',' ) - 2 )    AS id
    ,    SUBSTR ( alle_linier , INSTR ( alle_linier ,  ',' ) + 1, INSTR (alle_linier || '#','#',2 )-(INSTR ( alle_linier , ',' ) + 1))    AS linie
    ,    SUBSTR ( alle_linier , 1 + INSTR ( alle_linier || '#'  , '#' ,2 ) -1 )   AS tilbage_linier
FROM    metteordrer2
UNION ALL
select  SUBSTR (tilbage_linier , 2, INSTR ( tilbage_linier  || ',' , ',' ) - 2 )    AS id
    ,    SUBSTR ( tilbage_linier , INSTR ( tilbage_linier  , ',') + 1, instr(tilbage_linier || '#','#',2 )-(INSTR ( tilbage_linier, ',' ) + 1))    AS linie
    ,    SUBSTR ( tilbage_linier , 1 + INSTR ( tilbage_linier || '#'  , '#' ,2 ) -1 )   AS tilbage_linier
FROM    alle_linier
WHERE    tilbage_linier is not null
select id, linie from alle_linier;
{code}
It produced this:
{code}
p1     1525,1864,1880,1957,2036,2042,2043, 1525,1864,1920,1942,1948,1952,1957, 1525,1863,1943,1960,2030,2042,2046,2047,
