建表

CREATE TABLE `usertb` (
  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
  `uname` varchar(20) DEFAULT NULL,
  `ucreatetime` datetime DEFAULT NULL,
  `age` int(11) DEFAULT NULL,
  UNIQUE KEY `id` (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=76601101 DEFAULT CHARSET=utf8 ROW_FORMAT=COMPACT
 

建立儲存過程
