Answer 1

in this case if a change my range from 2 - 11 it does not works. In that case, I would use pipelined function :
SQL> drop table rehman ;
Table dropped.
SQL> create table rehman as
  2  select 1 id from dual union all
  3  select 3 id from dual union all
  4  select 5 id from dual union all
  5  select 7 id from dual union all
  6  select 9 id from dual ;
Table created.
SQL>
SQL>
SQL> create or replace type TblId as table of number
  2  /
Type created.
SQL>
SQL> create or replace function Tbl_rehman(p_start number, p_end number)
  2   RETURN TblId
  3   PIPELINED
  4  IS
  5  BEGIN
  6   FOR x IN p_start..p_end
  7   LOOP
  8       PIPE ROW( x );
  9   END LOOP;
10   RETURN;
11  END;
12  /
Function created.
