实现效果
准备工作
创建数据表和导入测试数据
CREATE TABLE `users` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(30) DEFAULT NULL COMMENT '账号',
`email` varchar(30) DEFAULT NULL COMMENT '密码',
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
INSERT INTO `users` VALUES ('1', 'admin', 'admin@qq.com');
INSERT INTO `users` VALUES ('2', 'xiaoming', '123456@qq.com');
INSERT INTO `users` VALUES ('3', 'xiaoming1', '123456@qq.com');
INSERT INTO `users` VALUES ('4', 'xiaoming2', '123456@qq.com');
INSERT INTO `users` VALUES ('5', 'xiaoming3', '123456@wy.com');
INSERT INTO `users` VALUES ('6', 'xiaoming4', '123456@wy.com');
INSERT INTO `users` VALUES ('7', 'xiaoming5', '123456@wy.com');
INSERT INTO `users` VALUES ('8', 'xiaoming6', '123456@wy.com');
INSERT INTO `users` VALUES ('9', 'xiaoming7', '123456@wy.com');
