Problem with Nested Table

Question

I am trying to make a nested table receive an arbitrary number of values (from a shuttle) through a loop, and then insert the table into a table of nested table in my database. The problem I am having is that when I try to insert more than one value into the nested table, it will only insert the last item in the loop into the database. Thanks in advance.
This is the code I used to create my objects:
create or replace type OUTPUT_TY as object( ATTRIBUTE_ID Number(8) )
create or replace type OUTPUTS_NT as table of OUTPUT_TY
This is my actual code in ApEx:
declare
temp_NT OUTPUTS_NT;
temp_TY OUTPUT_TY;
temp Number(10);
l_vc_arr2 htmldb_application_global.vc_arr2;
begin
temp_nt := outputs_nt();
l_vc_arr2 := HTMLDB_UTIL.string_to_table (:P2_SHUTTLE, ':');
FOR i IN 1 .. l_vc_arr2.COUNT
LOOP
temp_ty := output_ty(l_vc_arr2(i)) ;
temp_NT:= outputs_nt(temp_ty);
END LOOP;
INSERT INTO OUTPUT_TEST values (temp_NT);
commit;
end;

Answer 1

> temp_NT:= outputs_nt (temp_ty);You are not extending the nested table / collection, you are simply assigning an entirely new collection to it for each element of l_vc_arr2.
Try something like...
FOR i IN 1 .. l_vc_arr2.COUNT LOOP
   temp_ty := output_ty (l_vc_arr2 (i));
   temp_nt.EXTEND;
   temp_nt (temp_nt.LAST) := temp_ty;
END LOOP;Or perhaps more succintly...
FOR i IN 1 .. l_vc_arr2.COUNT LOOP
   temp_nt.EXTEND;
   temp_nt (temp_nt.LAST) := output_ty (l_vc_arr2 (i));
END LOOP;
