Help in joining nested table with regular table

Question

Im creating a nested table codelist as object prtcnpt_info. In a anonymous block im declaring t_code as nested table type codelist.
Now when i try to join the nested table with the regular oracle DB table and i get error: PL/SQL: ORA-00904: "COLUMN_VALUE": invalid identifier.
Please help me on this and provide tutorial link pertaining to this concepts..Below is the code i wrote
--Code Start;
create or replace type prtcnpt_info as object ( id number
,name varchar2(200)
,code varchar2(30));
create type codelist is table of prtcnpt_info;
declare
t_code codelist;
begin
select prtcnpt_info(b.pid ,b.name ,pt.code) bulk collect into t_code
from part pt
,mc_code b
where pt.cd in ('AAA','BBB')
and pt.ptype_id=b.pt_type_id;
INSERT INTO table ( ID
,RUN_ID
,DATA
,P_ID
SELECT id
     ,run_id
     ,data
     ,prtct.id ----> 1
FROM table_2 t2
,(select column_value from table(t_code)) prtct
WHERE prtct.id=t2.P_ID; ------> 2
end;
--Code End;
also from the anonymous block
1 => is this correct way to get value of id (b.pid) from the nested tablet_code aliased as prtct ?
2 => is this correct way to join the nested table with regular table? i want to join the column id's in both the tables.

When you create a table type without an object, i.e. a single column type like this you will get the column name as COLUMN_VALUE.
