+<h1>Adding Database prefixes manually</h1>
+<p>If you have configured a database prefix and would like to add it in manually for, you can use the following.</p>
+<p><code>$this->db->dbprefix('tablename');<br />
+// outputs prefix_tablename</code></p>
<h1>Protecting identifiers</h1>
<p>In many databases it is advisable to protect table and field names - for example with backticks in MySQL. Active Record queries are automatically protected, however if you need to manually protect an identifier you can use:</p>
<p><code>$this->db->protect_identifier('table_name');</code></p>
