首先，我们先建立数据用表coverage
--
-- 表的结构 `coverage`
--
CREATE TABLE IF NOT EXISTS `coverage` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`pid` int(10) unsigned DEFAULT NULL,
`coverageName` varchar(100) DEFAULT NULL,
`coverageDesc` varchar(200) DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `pid` (`pid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=20 ;
--
-- 转存...
