Dear Monks, I am working with the DBI module, and I have a small problem. I have a select statement that will retrieve rows, based on a name. What I want to do is using the name, I want to determine if the name already exists in the database. If it doesn't, I want to add it to the database. How do I check to see if the name already exists? Here is my code so far: 
sub checkDuplicateName
{
    my($db, $name) = @_;

    my $sth;
    my $rv;
    my @row;
    my $duplicate;
    
    $sth = $db->prepare('SELECT "Names" FROM Customers WHERE "Names" =
+ ?');
    $rv = $sth->execute($name);

    while(@row = $sth->fetchrow_array)
    {
        next;
    }

    if(undef $row[0])
    {
        $duplicate = 0;
    }
    else
    {
        $duplicate = 1;
    }

    return $duplicate;
}
