ORACLE SQL:Get all integers between two numbers

Question

Is there any way to select the numbers (integers) that are included between two numbers with SQL in Oracle; I don\'t want to create PL/SQL procedure or function.

This is a late addition. But the solution seems to be more elegant and easier to use.

It uses a pipelined function that has to be installed once:

CREATE TYPE number_row_type AS OBJECT 
(
  num NUMBER
);

CREATE TYPE number_set_type AS TABLE OF number_row_type;

CREATE OR REPLACE FUNCTION number_range(p_start IN PLS_INTEGER, p_end IN PLS_INTEGER)
    RETURN number_set_type
    PIPELINED
IS
    out_rec number_row_type := number_row_type(NULL);

BEGIN
  FOR i IN p_start .. p_end LOOP
    out_rec.num := i;
    pipe row(out_rec);
  END LOOP;

END number_range;
/

Then you can use it like this:

select * from table(number_range(1, 10));

NUM
---
  1
  2
  3
  4
  5
  6
  7
  8
  9
 10

The solution is Oracle specific.
