Syntax

DOUBLE ST_Distance_Sphere(DOUBLE x_lng, DOUBLE x_lat, DOUBLE y_lng, DOUBLE y_lat)

计算地球两点之间的球面距离，单位为米。传入的参数分别为X点的经度，X点的纬度，Y点的经度，Y点的纬度。

x_lng 和 y_lng 都是经度数据，合理的取值范围是 [-180, 180]。 x_lat 和 y_lat 都是纬度数据，合理的取值范围是 [-90, 90]。

example

mysql> select st_distance_sphere(116.35620117, 39.939093, 116.4274406433, 39.9020987219);
