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)'));
注意必須使用 ST_GeomFromText 函數，且 POINT() 里面是：經度+空格+緯度
查詢
1. 查看經緯度
SELECT address, ST_AsText(location) AS location FROM map;
2. 計算兩點之間的距離
SELECT ST_Distance_Sphere(POINT(121.590347, 31.388094),location) AS distant FROM map;
算出來的結果，單位是米
注意現在POINT()里面經緯度之間是逗號分隔的
3. 查詢距離小于1000m的地點，并由遠及近排序
復制代碼代碼如下:
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;
