Splitting the values in one column

Question

Hi there,
I have a column(userid) containing data like: 'abc,def,ghik'
I would like to make a kind of split function, something I would have wrote like this:
SELECT SPLIT(userid,',') FROM myTable WHERE userid = 'abc,def,ghik'
Would return:
abc
def
ghik
Then I could turn it in a stored proc in a way to send me back multi-recordset result, that's no problem.
I'm sure there's a way to split a string with a separator, just can't figure out how to do it.
Can someone help me ?
Thanks!

CREATE TABLE test ( id NUMBER, des
VARCHAR2(30) );
INSERT INTO test VALUES(15, 'a;b;c;d;e;f;g;') ;
DELETE from test;
SELECT * FROM test;
SELECT id, SUBSTR(';' || des || ';', INSTR(';'
|| des || ';' , ';', 1, rn) +1,
INSTR(';' || des || ';' , ';', 1, rn +
';', 1, rn + 1) - INSTR(';' || des || ';' ,
';', 1, rn) -1) des
FROM test , (SELECT  ROWNUM rn   FROM
all_objects
WHERE ROWNUM <= ( SELECT LENGTH(des) -
) - (LENGTH(REPLACE(des, ';'))) / LENGTH(';') + 1
FROM test )) ;[pre]
Hmm....that looks awfully familiar ;-)
Come and try this one, why not try this one !
