创建测试用表
既然我们需要测试，那么我们就需要建立在数据库中建立一个测试表，这个表建的很简单，SQL语句为：DROP TABLE IF EXISTS `user_t`; CREATE TABLE `user_t` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_name` varchar(40) NOT NULL, `password` varchar(255) NOT NULL, `age` int(4) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; /*Data for the table `user_t` */ insert into `user_t`(`id`,`user_name`,`password`,`age`) values (1,'测试','sfasgfaf',24);ql] view
