Am trying to use DISTINCT clause  to get all ages for users named john, but dont know why am getting single resluts


|      TABLE   USERS         |
+--------+-------------------+
| ID     | NAMES    |  AGE   |
+--------+----------|--------+
|      1 | John     |     35 |
|      2 | Mike     |     31 |
|      3 | John     |     56 |
+--------+-------------------+

my $get_age = $DBH->prepare("SELECT DISTINCT AGE FROM USERS WHERE NAMES = ?");
$get_age->execute('John');
$age = $get_age->fetchrow();
