body: <p>im using codeigniter 2.0.2 and this is from its userguide</p>
  
  <pre><code>$data = array(
                 'title' =&gt; $title,
                 'name' =&gt; $name,
                 'date' =&gt; $date
              );
  
  $this-&gt;db-&gt;where('id', $id);
  $this-&gt;db-&gt;update('mytable', $data); 
  </code></pre>
