<p>In order to store sessions, you must first create a database table for this purpose. Here is the basic
prototype (for MySQL) required by the session class:</p>
-<textarea class="textarea" style="width:100%" cols="50" rows="8">
+<textarea class="textarea" style="width:100%" cols="50" rows="10">
CREATE TABLE IF NOT EXISTS `ci_sessions` (
-session_id varchar(40) DEFAULT '0' NOT NULL,
-ip_address varchar(16) DEFAULT '0' NOT NULL,
-user_agent varchar(50) NOT NULL,
-last_activity int(10) unsigned DEFAULT 0 NOT NULL,
-user_data text DEFAULT '' NOT NULL,
-PRIMARY KEY (session_id)
-);</textarea>
+ session_id varchar(40) DEFAULT '0' NOT NULL,
+ ip_address varchar(16) DEFAULT '0' NOT NULL,
+ user_agent varchar(50) NOT NULL,
+ last_activity int(10) unsigned DEFAULT 0 NOT NULL,
+ user_data text NOT NULL,
+ PRIMARY KEY (session_id),
+ KEY `last_activity_idx` (`last_activity`)
+);

<p><strong>Note:</strong> By default the table is called <dfn>ci_sessions</dfn>, but you can name it anything you want
as long as you update the <kbd>application/config/config.php</kbd> file so that it contains the name you have chosen.
