5 * Resource Implementation based on the Custom API to use
6 * MySQL as the storage resource for Smarty's templates and configs.
7 * Note that this MySQL implementation fetches the source and timestamps in
8 * a single database query, instead of two separate like resource.mysql.php does.
10 * <pre>CREATE TABLE IF NOT EXISTS `templates` (
11 * `name` varchar(100) NOT NULL,
12 * `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
14 * PRIMARY KEY (`name`)
15 * ) ENGINE=InnoDB DEFAULT CHARSET=utf8;</pre>
17 * <pre>INSERT INTO `templates` (`name`, `modified`, `source`) VALUES ('test.tpl', "2010-12-25 22:00:00", '{$x="hello world"}{$x}');</pre>
