- * MySQL Resource
- * Resource Implementation based on the Custom API to use
- * MySQL as the storage resource for Smarty's templates and configs.
- * Table definition:
- * <pre>CREATE TABLE IF NOT EXISTS `templates` (
- *   `name` varchar(100) NOT NULL,
- *   `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
- *   `source` text,
- *   PRIMARY KEY (`name`)
- * ) ENGINE=InnoDB DEFAULT CHARSET=utf8;</pre>
- * Demo data:
- * <pre>INSERT INTO `templates` (`name`, `modified`, `source`) VALUES ('test.tpl', "2010-12-25 22:00:00", '{$x="hello world"}{$x}');</pre>
