title: double values on mysql
body: <p>hi i have a db schema like this:</p>
  
  <pre><code>poll_option:
  +----+---------------------+
  | question_id | option     |
  +----+---------------------+
  |      1      | forever    |
  +----+---------------------+
  
  poll_clicks:
  +--------------------+------------+
  | question| meta_key | meta_value |
  +---------+----------+------------+
  |    1    |     ip   |192.168.1.10| 
  +---------+----------+------------+
  
  result i want:
  +--------------------+------------+
  |  option | meta_key | meta_value |
  +---------+----------+------------+
  | forever |     ip   |192.168.1.10| 
  +---------+----------+------------+
  </code></pre>
  
  <p>This is my query:</p>
  
  <pre><code>SELECT p.* FROM poll_clicks p, poll_option m 
    WHERE m.question_id=p.question 
  </code></pre>
  
  <p>but Im getting repeated values,
  any ideas?</p>
  
  <p>EDIT: just need to add the "option" to  "poll_click" result</p>
