CREATE TABLE `book` (
      `id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '图书ID',
      `name` varchar(100) NOT NULL COMMENT '图书名称',
      `number` int(11) NOT NULL COMMENT '图书数量',
      `detail` varchar(200) NOT NULL COMMENT '图书描述',
      PRIMARY KEY (`book_id`)
    ) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='图书表'
