On a unix box with sqlplus, the following works quite well:

#!/bin/sh

if [ "$1" = "" ]
then

	cat << EOF
usage:		flat un/pw [tables|views]

example:	flat scott/tiger emp dept

description:	Select over standard out all rows of table or view with 
		columns delimited by tabs.
EOF
	exit

fi

PW=$1
shift

for X in $*
do
sqlplus -s $PW << EOF > /tmp/flat$$.sql

set	wrap off
set	feedback off
set	pagesize 0
set	verify off
prompt	select
select	lower(column_name)||'||chr(9)||'
from	user_tab_columns
where	table_name = upper('$X') and
	column_id != (select max(column_id) from user_tab_columns where
			 table_name = upper('$X'))
/
select	lower(column_name)
from	user_tab_columns
where	table_name = upper('$X') and
	column_id = (select max(column_id) from user_tab_columns where
			 table_name = upper('$X'))
/
prompt	from	$X
prompt	/
prompt	exit

exit
EOF
sqlplus -s $PW << EOF

set	wrap off
set	feedback off
set	pagesize 0
set	verify off

set trimspool on
set linesize 5000
start /tmp/flat$$.sql
exit
EOF
rm /tmp/flat$$.sql
done
