本篇文章給大家?guī)?lái)的內(nèi)容是關(guān)于mysql的geometry類型處理經(jīng)緯度距離的方法介紹，有一定的參考價(jià)值，有需要的朋友可以參考一下，希望對(duì)你有所幫助。
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(shù)，且 POINT() 里面是：經(jīng)度+空格+緯度
查詢
1. 查看經(jīng)緯度
SELECT address, ST_AsText(location) AS location FROM map;
2. 計(jì)算兩點(diǎn)之間的距離
SELECT ST_Distance_Sphere(POINT(121.590347, 31.388094),location) AS distant FROM map;
算出來(lái)的結(jié)果，單位是米
注意現(xiàn)在POINT()里面經(jīng)緯度之間是逗號(hào)分隔的
3. 查詢距離小于1000m的地點(diǎn)，并由遠(yuǎn)及近排序
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;
