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 distanceFROM locationpointORDER BY distance;
