<p>You may also use the <dfn>$this->db->set()</dfn> function described above when performing updates.</p>
+<h2>$this->db->update_batch();</h2>
+<p>Generates an update string based on the data you supply, and runs the query. You can either pass an
+<strong>array</strong> or an <strong>object</strong> to the function. Here is an example using an array:</p>

+<code>
+$data = array(<br/>
+ array(<br />
+ 'title' => 'My title' ,<br />
+ 'name' => 'My Name 2' ,<br />
+ 'date' => 'My date 2'<br />

+ 'title' => 'Another title' ,<br />
+ 'name' => 'Another Name 2' ,<br />
+ 'date' => 'Another date 2'<br />
+ )<br/>
+);<br />

+$this->db->update_batch('mytable', $data, 'title');

+// Produces: <br />
+// UPDATE `mytable` SET `name` = CASE<br />
+// WHEN `title` = 'My title' THEN 'My Name 2'<br />
