Select statement REF oracle - sql

Question

I need some help with creating a select statement that will use a ref.
I managed to insert the values fine but when i try to extract the values with a where statement the output is either that the datatype is wrong or it will output the two tables and the data they both contain.
this is just an example:
Create or replace table1_Type as object {
id integer,
dateStart date,
etc varchar2(20));
}
/
create table table1 of table1_type;
Create or replace table2_type as object
id integer,
items varchar2(30),
datePurchased varchar2(20),
table1_Ref REF table1_type);
/
create table table2 of table2_type;
so i tried
Select * from table2 a, table1 b where table1.id = table2.table1_ref
Select * from table2 a, table1 b where table1.id = deref(b.table1_ref)
which does not work.
Iam new to this so sorry if i didnt explain properly. What i am trying to do is to select the items for example that were purchased by table1/id so the output should only display
the items that were purchased by a certain id.

Create or replace type table1_Type as object (
id integer,
dateStart date,
etc varchar2(20));
-- TYPE TABLE1_TYPE compiled
create table table1 of table1_type;
-- table TABLE1 created.
Create or replace type table2_type as object(
id integer,
items varchar2(30),
datePurchased varchar2(20),
table1_Ref REF table1_type);
-- TYPE TABLE2_TYPE compiled
create table table2 of table2_type;
--table TABLE2 created.
INSERT INTO table1 VALUES(table1_Type(1, SYSDATE, 'etc1...'));
INSERT INTO table1 VALUES(table1_Type(2, SYSDATE, 'etc2...'));
SELECT REF(t)
FROM table1 t
WHERE id = 1;
-- [TST.TABLE1_TYPE]
DECLARE
l_table_1_id_1 REF table1_Type;
l_table_1_id_2 REF table1_Type;
BEGIN
SELECT REF(t)
INTO l_table_1_id_1
FROM table1 t
WHERE id = 1;
SELECT REF(t)
INTO l_table_1_id_2
FROM table1 t
WHERE id = 2;
INSERT INTO table2 VALUES (21, 'item21', SYSDATE, l_table_1_id_1);
INSERT INTO table2 VALUES (22, 'item22', SYSDATE, l_table_1_id_2);
END;
-- anonymous block completed
SELECT COUNT(*) FROM table1;
-- 2
SELECT COUNT(*) FROM table2;
-- 2
SELECT * FROM table1;
/*
1 2013-06-16 03:51:50 etc1...
2 2013-06-16 03:52:05 etc2...
*/
SELECT * FROM table2;
/*

22 item22 2013-06-16 04:06:26 [TST.TABLE1_TYPE]
*/
SELECT *
FROM table1 t1
JOIN table2 t2
ON REF(t1) = t2.table1_Ref;
/*
1 2013-06-16 03:51:50 etc1... 21 item21 2013-06-16 04:06:26 [TST.TABLE1_TYPE]
