创建数据库字段属性样例
Create table shop (
station_id int(3) primary key,
Location POINT
);
st_distance 函数
st_distance 函数是从mysql5.6.1才加入的
SET @g1 = POINT(1,1), @g2 = POINT(2,2);
select st_distance (@g1, @g2); 输出结果：1.4142135623730951
st_distance 计算的结果单位是度，需要乘111195（地球半径6371000*PI/180）是将值转化为米.
例 距离39.54,116.2坐标50公里最近的点
SELECT
station,
( st_distance
( Location, point
(39.54,116.2) ) /0.0111) AS distance
FROM geostation
HAVING distance<50
ORDER BY distance
ASC LIMIT 0,1
