MySQL怎么計算兩坐標距離并排序

環境

MySQL5.6

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

表結構及數據

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, '山東', '濟南', 116.938477, 36.597889),        (2, '河北', '石家莊', 114.477539, 38.030786),        (3, '浙江', '杭州', 120.058594, 30.334954),        (4, '河南', '鄭州', 113.629, 34.744),        (5, '安徽省', '合肥', 117.170, 31.520);

查詢方式

(以內蒙古自治區呼和浩特市為計算中心)

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;
