ok, i now have:
#fetch two colums (username , password) 
while($hash_ref = $sth->fetchrow_hashref){

#dereference
my %values=%$hash_ref;

#print out usernames
print $values{'username'};}

[download]
I can print out all the usernames from the database but do you know how I can match one of these usernames to 
$testUsername

[download]
I need to print off something like "username matched"
