field contains spaces : sql

A field may have data such as 'This is a test'.

If I select this field within a unix for loop the result of this query is

This
is
a
test.

How can I get it so that the result stays on one line.

The unix code is below.

number=`db2 -x "select distinct(number) from test"`

for n in $number
do
echo "getting data for number"
data=`db2 -x "select data from test where number= $number"`
for d in $data
do
echo $d
done
done

result is

1 This
1 is
1 a
1 test

ideal results
1 This is a test
