Loop in bash file for mysql

Hi,
I'm having problems with a script which some of you helped me with last week. It's a script to check the status of orders in an SQL database, and if the count(*) is zero, then the script stops. If it's non-zero, the script echos the result to a file and then in cron, I cat the file and mail it.

First thing first, this script is pig-ugly with all of the echos in there, so I need to tidy that up, but more important is the fact that the second part - from where I've inserted ## second part -- just constantly returns the same order code.

Oh, and it loops.

What a mess.

Can someone help me ?

Thanks.

Code:

#!/bin/sh

## get date 

today=`date +"%d-%m-%Y-%H-%S"`

if [ -f /root/extrac.txt ]; then 
	/bin/rm /root/extrac.txt
fi

#### check orders

orderStatus=$(/usr/bin/mysql -N -B mybase -e 'SELECT COUNT(*) FROM orders as o JOIN users as u ON o.userpk=u.pk WHERE o.createdts BETWEEN (now() - INTERVAL 1 day) AND (now() - INTERVAL 4 hour) AND o.p_omsstate=1 AND u.name != "wotsit" AND u.p_username NOT LIKE "e-mail_address@domain.co.uk";')

/bin/echo "" > /root/extrac.txt
/bin/echo "The date is $today" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt
/bin/echo "We have verified the number of orders still in 'state' state" >> /root/extrac.txt
/bin/echo "after four hours." >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt

if [ $orderStatus != "0" ]; then
	/bin/echo "" >> /root/extrac.txt
	/bin/echo "" >> /root/extrac.txt
	/bin/echo "The number of orders in this state is not zero." >> /root/extrac.txt
	/bin/echo "" >> /root/extrac.txt
	/bin/echo "As such, the web order numbers are echoed below : " >> /root/extrac.txt
	/bin/echo "" >> /root/extrac.txt

## second part 
orderStatus=$(/usr/bin/mysql -N -B mybase -e 'SELECT Code FROM orders as o JOIN users as u ON o.userpk=u.pk WHERE o.createdts BETWEEN (now() - INTERVAL 1 day) AND (now() - INTERVAL 4 hour) AND o.p_omsstate=1 AND u.name != "wotsit" AND u.p_username NOT LIKE "e-mail_address@domain.co.uk";')

while [ $result ]
do
	/bin/echo "" >> /root/extrac.txt
	/bin/echo "" >> /root/extrac.txt
	/bin/echo "$result" >> /root/extrac.txt
	/bin/echo "" >> /root/extrac.txt
	/bin/echo "" >> /root/extrac.txt
done

exit 0 
fi 

/bin/echo "" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt
/bin/echo "The number of orders is zero, and as such, no web order numbers are available" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt

/bin/echo "Any questions, please e-mail me@myaddress.com" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt
/bin/echo "-------------------------------------------------------------" >> /root/extrac.txt
/bin/echo "" >> /root/extrac.txt

gzexe

GZEXE(1)						      General Commands Manual							  GZEXE(1)

NAME

       gzexe - compress executable files in place

SYNOPSIS

       gzexe name ...

DESCRIPTION

       The  gzexe  utility  allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
       penalty in performance).  For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files:
	   -rwxr-xr-x  1 root root 1026675 Jun	7 13:53 /usr/bin/gdb
	   -rwxr-xr-x  1 root root 2304524 May 30 13:02 /usr/bin/gdb~
       /usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file.  You can remove /usr/bin/gdb~ once  you  are
       sure that /usr/bin/gdb works properly.

       This utility is most useful on systems with very small disks.

OPTIONS

       -d     Decompress the given executables instead of compressing them.

SEE ALSO

       gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)

CAVEATS

       The  compressed executable is a shell script.  This may create some security holes.  In particular, the compressed executable relies on the
       PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).

BUGS

       gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually  in  some  cases,
       using chmod or chown.
