Creating Fixed length Text file from Oracle 9i table.

Hi,
  I am trying to generate a fixed length text file from Oracle 9i table.
Ex:
  My expected output is
  Positon       Field
  1-10           First Name
  11-20         Last Name
   20-40        Address
My output is going to look like this:
Steveson  Cathy     Washington DC
Robbs       Valles    Maryland

What is best way i can do, UTL_FILE or Spool or some other approach? If so how to do?

Thanks.

spool approach.

set heading off
set pages 0
set echo off

select rpad(firstName,10)||rpad(lastName,10)||rpad(address,20)
from <table>;
0

Or you can define columns (also spool, the rpad-approach wou8ld also work with utl_file)

set heading off
set pages 0
set echo off
set trimspool on
col firstName format a10
col lastName format a10
col address format a20

spool filename

select firstName, lastName, address
from <table>;

spool off
