Answer 1

When you use this method ...
type vdeptno is table of number;
v_deptno vdeptno;
You need to allocate space to the object prior to inserting into it , (use .EXTENDS for this). Or you need to initialize it while declaring it.
or try the following
SQL> declare
2 type vdeptno is table of number;
3 v_deptno vdeptno;
4 TYPE e_tab is table of PLS_INTEGER INDEX BY PLS_INTEGER;
5 empno_tab e_tab;
6 Begin
7 Select empno bulk collect into empno_tab FROM emp;
8 FOR i in empno_tab.FIRST..empno_tab.LAST
9 LOOP
10 dbms_output.put_line(empno_tab(i));
11 Select deptno bulk collect into v_deptno
12 FROM emp
13 where empno=empno_tab(i);
14 END loop;
15 END;
