CREATE TABLE `jxc_orderdetail` (
  `detail_id` int(11) NOT NULL AUTO_INCREMENT,
  `order_no` varchar(20) DEFAULT '' COMMENT '订单编号',
  `pro_no` varchar(20) DEFAULT '' COMMENT '产品编号',
  `pro_name` varchar(100) DEFAULT '' COMMENT '产品名字',
  `pro_number` int(11) DEFAULT '0' COMMENT '产品数量',
  `pro_price` decimal(10,2) DEFAULT '0.00' COMMENT '产品单价',
  `pay_price` decimal(10,2) DEFAULT '0.00' COMMENT '最后支付',
  PRIMARY KEY (`detail_id`)
) ENGINE=MyISAM AUTO_INCREMENT=139707 DEFAULT CHARSET=utf8;



insert  into `jxc_orderdetail`(`detail_id`,`order_no`,`pro_no`,`pro_name`,`pro_number`,`pro_price`,`pay_price`) values (139704,'H140523000001','130001','美国莎娜琳',2,'78.00','1000.00'),(139705,'H140524000001','49101815101237','移花宫速效细肤祛痘乳100ML',1,'133.00','1000.00'),(139706,'H140524000001','ECS000160','移花宫速效控油嫩肤水12ML',1,'39.00','1000.00');

SELECT order_no,GROUP_CONCAT(pro_name,'*',pro_number) FROM jxc_orderdetail GROUP BY order_no

结果：

本例子是多个字段聚合，如果只是一个字段 GROUP_CONCAT 里面只有一个参数即可
