Sql query output to ksh arrays

day_table table contains data like
12-May-2005 15-May-2005
10-Jun-2005 27-Jun-2005
02-Dec-2005 30-Dec-2005

I want to assign these values to a 2D array and later use them 1 by 1.
I am doing following, but its not working...

set -A days
`sqlplus -s $MMUSER/$PASSWORD@$ORACLE_SID <<EOL

SET HEAD OFF
SET FEEDBACK OFF

SELECT start_date,
end_date
FROM day_table;

EXIT SQL.SQLCODE;
EOL`

i=0
while [ $i -lt ${#days[*]} ]
do
print ${days[$i]}
(( i=i+1 ))
done

Can anybody help me out?
