MySQL的geometry类型处理经纬度距离的方法介绍

INSERT INTO map (id, address, location) VALUES (1, 'somewhere', ST_GeomFromText('POINT(121.366961 31.190049)'));

SELECT address, ST_AsText(location) AS location FROM map;

SELECT ST_Distance_Sphere(POINT(121.590347, 31.388094),location) AS distant FROM map;

SELECT id, address, ST_Distance_Sphere(POINT(121.590347, 31.388094),location) AS distant FROM map WHERE ST_Distance_Sphere(POINT(121.590347, 31.388094),location) < 1000 ORDER BY distant;
