Question : rmdir

Hi,

I am doing a project with perl and mysql.

I am getting the lastname of the user and create a directory with that lastname:

     mkdir "$lastname";

and I also added that lastname to my table "student".

Now, I am trying to delete that directory by only getting the   $id    from the user:
   
     my $sql = "SELECT lastname FROM student where student_id =$id ";
     my $sth = $dbh->prepare($sql) or die "cannot prepare";
     $sth->execute() or die "cannot execute";

     rmdir "$lname";

I know that I should not write "$lname" in the rmdir function, but what should I write there? or is there another way to remove the directory?? How can I assign the value of the retrieved data by that SELECT statement to another scalar value, so that I can write that value inside the rmdir function.?

Thank you

Answer : rmdir

$lname =  $sth->fetchrow;
rmdir $lname or warn "$lname $!";
