Collection in where not working

Question

Hi guys,
I haven't manage to figure out why this code does not work... maybe I'm missing something and I do not see it
declare
      type tn is table of number;
      --n tn; -- not good => pls 00642 local type collection
      n ar_utl2.table_of_number_type; -- type table_of_number_type is table of number;
begin
   select * bulk collect into n from (
   select 1144 nr from dual
   union
   select 1004 nr from dual
   for i in (
     --select * from ar_intermediaries where intermediary_id member of n --ora 21700 object does not exist
     --select * from ar_intermediaries where intermediary_id in (select t.column_value from table(cast(n as ar_utl2.table_of_number_type))t) --invalid datatype ar_utl2.table_of_number_type
     select * from ar_intermediaries where intermediary_id in (select t.column_value from table(n)t) --ora 21700 object does not exist
   ) loop
     dbms_output.put_line('got it');
   end loop;
end;Can you help please?

n tn; not good => pls 00642 local type collectionYou need to create a schema level array to use it in SQL.
create type numbers_ntt is table of number;
select * from ar_intermediaries where intermediary_id member of n ora 21700 object does not exist
select * from ar_intermediaries where intermediary_id in (select t.column_value from table(cast(n as ar_utl2.table_of_number_type))t) invalid datatype >ar_utl2.table_of_number_type
select * from ar_intermediaries where intermediary_id in (select t.column_value from table(n)t) --ora 21700 object does not existYou can use this:
where t.nr in (select column_value
                      from table(numbers_nt)); or this
from t,
           table(numbers_nt) nt
     where t.nr = nt.column_value;------
Demo setup
create type numbers_ntt is table of number;
create table t (nr integer);
insert into t values (1144);
insert into t values (1004);
create procedure print(numbers_in    in numbers_ntt,
                       array_name_in in varchar2 default 'The array') is
begin
    dbms_output.put_line(array_name_in || ' - contains ' || numbers_in.count ||
                         ' values:');
    --There are no gaps with bulk_collect array, because SQL engine inserts elements consecutively ,it starts with 1
    -- and substitutes the old elements
    for i in numbers_in.first .. numbers_in.last
    loop
        dbms_output.put_line(numbers_in(i));
    end loop;
    dbms_output.new_line;
end print;Another example:
declare
    numbers_nt       numbers_ntt; -- schema-level type
    numbers2_nt      numbers_ntt; -- schema-level type
begin
    select * bulk collect
      into numbers_nt
      from t;
    print(numbers_nt, 'numbers_nt');
    numbers_nt(2) := 1000;
    print(numbers_nt, 'numbers_nt');
    select t.nr bulk collect
      into numbers2_nt
      from t
     where t.nr in (select column_value
                      from table(numbers_nt));
    print(numbers2_nt, 'numbers2_nt');
    numbers_nt.extend;
    numbers_nt(numbers_nt.last) := 1004;
    print(numbers_nt, 'numbers_nt');
    -- with join
    select t.nr bulk collect
      into numbers2_nt
      from t,
           table(numbers_nt) nt
     where t.nr = nt.column_value;
    print(numbers2_nt, 'numbers2_nt');
end;The output:
numbers_nt - contains 2 values:
1144
1004
numbers_nt - contains 2 values:
1144
1000
numbers2_nt - contains 1 values:
1144
numbers_nt - contains 3 values:
1144
1000
1004
numbers2_nt - contains 2 values:
1144
1004
