创建表

DROP TABLE IF EXISTS `pb_area`;  
CREATE TABLE `pb_area` (  
  `id` int(10) NOT NULL COMMENT 'ID',  
  `areaname` varchar(50) NOT NULL COMMENT '栏目名',  
  `parentid` int(10) NOT NULL COMMENT '父栏目',  
  `shortname` varchar(50) DEFAULT NULL COMMENT '简称',  
  `areacode` int(6) DEFAULT NULL COMMENT '区号',  
  `zipcode` int(10) DEFAULT NULL COMMENT '邮政编码',  
  `pinyin` varchar(100) DEFAULT NULL COMMENT '拼音',  
  `lng` varchar(20) DEFAULT NULL COMMENT '经度',  
  `lat` varchar(20) DEFAULT NULL COMMENT '纬度',  
  `level` tinyint(1) NOT NULL,  
  `position` varchar(255) NOT NULL,  
  `sort` tinyint(3) unsigned DEFAULT '50' COMMENT '排序',  
  PRIMARY KEY (`id`)  
) ENGINE=InnoDB DEFAULT CHARSET=utf8;  、

查询语句

SET @pt2 = ST_GeomFromText('POINT(116.405289 39.904987)');  
SELECT *,ST_Distance_Sphere(ST_GeomFromText(CONCAT('POINT(',lng,' ',lat,')')), @pt2) as distance  FROM pb_area  
WHERE ST_Distance_Sphere(ST_GeomFromText(CONCAT('POINT(',lng,' ',lat,')')), @pt2) < 10000 ORDER BY distance  

POINT(116.405289 39.904987)为北京坐标，ST_Distance_Sphere(pt1,pt2)计算两点之间的距离， 10000是距离米数
