Generate fixed length txt file
hi,

i am using below query to generate the fixed length txt file. this sql is being called from shell script.
This is supposed to be a fixed record file with the below definitions. There must be 2 byte filler after the CAT_ID AND each line should have total of 270 bytes.

Code:
field         length
------------------------
EMAIL_ADDR  1-255
CAT_ID      256-268
FILLER      269-270

issues
-------
1) i am not getting 270 byte file if there is only one record.
2) 3rd col doesn't have 2 byte length as it is null.the cursor doesn't go beyond 268 position.

please advise.


test.sql

Code:
set linesize 1000;
set newpage 0;
SET PAGESIZE 0;
SET ECHO OFF;
SET FEEDBACK OFF;
SET HEADING OFF;
SET VERIFY OFF;
whenever sqlerror exit failure;
whenever oserror exit failure;
alter session enable parallel dml;
SELECT DISTINCT rpad(EMAIL_ADDR,255),rpad(CAT_ID,13),rpad(' ',3) filler
  FROM T1;

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
