Answer 1

create or replace type dept_ot as object (
deptno NUMBER(2),
dname VARCHAR2(14),
loc VARCHAR2(13));
create table dept
(deptno number
,dname varchar2(14)
,loc varchar2(13)
insert into dept values (10, 'x', 'xx');
insert into dept values (20, 'y', 'yy');
insert into dept values (30, 'z', 'zz');
select dept_ot (deptno, dname, loc)
  from dept
create type dept_nt is table of dept_ot
declare
   l_depts dept_nt;
begin
   select dept_ot (deptno, dname, loc)
     bulk collect
     into l_depts
     from dept
   for i in l_depts.first .. l_depts.last
   loop
      dbms_output.put_line (l_depts(i).deptno);
      dbms_output.put_line (l_depts(i).dname);
      dbms_output.put_line (l_depts(i).loc);    
   end loop;
end;
