Join Table with Collection Array Type

Question

Hi All,
I'm trying to join 2 types of tables (real table and array collection type)
When I wrote this code:
Declare
-- Types
Type cArr Is Record (col1 Number);
Type tArr Is Table Of cArr Index By Binary_Integer;
-- Objects
ocArr cArr;
otArr tArr;
Begin
-- Set Array Table
ocArr.col1 := 1;
otArr(1) := ocArr;
ocArr.col1 := 3;
otArr(2) := ocArr;
-- Fetch Records
For Rec in (Select col1 From Table(otArr) Arr)
Loop
Dbms_Output.Put_Line(Rec.col1);
End Loop;
End;
I Get This Error:
ORA-06550: line 10, column 64:
PLS-00382: expression is of wrong type
ORA-06550: line 10, column 58:
PL/SQL: ORA-22905: cannot access rows from a non-nested table item
ORA-06550: line 10, column 21:
PL/SQL: SQL Statement ignored
I know that I can Use this as sn answer:
For Rec In 1..2
Loop
Dbms_Output.Put_Line(otArr(Rec).Col1);
End Loop;
But I need later on to use this collection join with another real table based on values compare like:
For Rec in (Select a.Col2 From a,(Select col1 From Table(otArr)) Arr Where a.Col1 = Arr.Col1)
Loop
Dbms_Output.Put_Line(Rec.col1);
End Loop;
Can someone tell me where I'm wrong and how to fix it?
Thanks,

Welcome to the forum.
Don't use a PL/SQL type, but an SQL type.
