MySQL怎么计算两坐标距离并排序

环境

MySQL5.6

https://dev.mysql.com/doc/refman/5.6/en/spatial-relation-functions-object-shapes.html#function_st-distance

表结构及数据

DROP TABLE IF EXISTS `locationpoint`; CREATE TABLE `locationpoint` (     `id`        int(11)       NOT NULL AUTO_INCREMENT,     `province`  varchar(20)   NOT NULL,     `city`      varchar(20)   NOT NULL,     `longitude` double(10, 3) NOT NULL,     `latitude`  double(10, 3) NOT NULL,     PRIMARY KEY (`id`) ) ENGINE = InnoDB   AUTO_INCREMENT = 1156   DEFAULT CHARSET = utf8;

INSERT INTO `locationpoint` VALUES (1, '山东', '济南', 116.938477, 36.597889),        (2, '河北', '石家庄', 114.477539, 38.030786),        (3, '浙江', '杭州', 120.058594, 30.334954),        (4, '河南', '郑州', 113.629, 34.744),        (5, '安徽省', '合肥', 117.170, 31.520);

查询方式

(以内蒙古自治区呼和浩特市为计算中心)

SELECT id,        city,        longitude,        latitude,        round(                    (                            st_distance(                                    point(longitude, latitude),                                    point(111.621094, 40.913513)                                ) / 0.0111                        ) * 1000            )            AS distance FROM locationpoint ORDER BY distance;
