+<h2>$this->db->insert_batch();</h2>
+<p>Generates an insert string based on the data you supply, and runs the query. You can either pass an
+<strong>array</strong> or an <strong>object</strong> to the function.  Here is an example using an array:</p>
+
+<code>
+$data = array(<br/>
+&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'My title' ,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'My Name' ,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'My date'<br />
+&nbsp;&nbsp;&nbsp;),<br />
+&nbsp;&nbsp;&nbsp;array(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' => 'Another title' ,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name' => 'Another Name' ,<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'date' => 'Another date'<br />
+&nbsp;&nbsp;&nbsp;)<br/>
+);<br />
+<br />
+$this->db->update_batch('mytable', $data);
+<br /><br />
+// Produces: INSERT INTO mytable (title, name, date) VALUES ('My title', 'My name', 'My date'),  ('Another title', 'Another name', 'Another date')</code>
