建表
CREATE TABLE `map` ( `id` int(11) NOT NULL, `address` varchar(255) NOT NULL DEFAULT '', `location` geometry NOT NULL, PRIMARY KEY (`id`), SPATIAL KEY `idx_location` (`location`) )
插入
INSERT INTO map (id, address, location) VALUES (1, 'somewhere', ST_GeomFromText('POINT(121.366961 31.190049)'));
注意必须使用 ST_GeomFromText 函数，且 POINT() 里面是：经度+空格+纬度
查询
1. 查看经纬度
SELECT address, ST_AsText(location) AS location FROM map;
2. 计算两点之间的距离
SELECT ST_Distance_Sphere(POINT(121.590347, 31.388094),location) AS distant FROM map;
算出来的结果，单位是米
注意现在POINT()里面经纬度之间是逗号分隔的
3. 查询距离小于1000m的地点，并由远及近排序
代码如下: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;
