how I delete a row in a table in Joomla?

I have a table 

id h_id t_id
 1   3   1
 2   3   2
 3   3   3
 4   4   2
 5   4   3

id is the primary key. I have not created a JTable for this table. Now I want to delete rows by h_id. Are there any method like which I can use without writing a sql DELETE query?

$db = JFactory::getDBO();
$row =& $this->getTable('tablename');
$row->delete($pk);

Any better solution will be greatly appreciated.

Solution 
  •          $db = & JFactory::getDBO();   
         $query = $db->getQuery(true);
         $query->delete($db->nameQuote('tablename'));             
         $query->where($db->nameQuote('h_id').'='.$db->quote($key));             
         $db->setQuery($query);
         $db->query();
