If the data is supposed to be strictly numeric, you can intercept the bad
data prior to running the sql.
X=''
while [ -z "$X" ]; do
echo ""
echo "Enter a number or Q to quit"
read X
if [ "$X" = "Q" ]; then
echo "Exiting ..."
exit 0
fi
if [ -z "$X" ]; then
echo ""
echo "That was a blank entry. Try again."
echo ""
continue
fi
if [ -n "`echo $X | sed -n '/[^0-9]/p'`" ]; then
echo ""
echo "You entered at least one non-numeric character."
echo "You entered ->${X}<-"
echo "Try again."
echo ""
X=""
continue
fi
done
