ST_DISTANCE_SPHERE was introduced in MariaDB 10.2.38, MariaDB 10.3.29, MariaDB 10.4.19 and MariaDB 10.5.10.

Syntax

ST_DISTANCE_SPHERE(g1,g2,[r])

Description

Returns the spherical distance between two geometries (point or multipoint) on a sphere. The optional radius r is in meters, must be postive, and defaults to the Earth's radius (6370986 meters) if not specified. If not given valid inputs, NULL is returned.

Example

set @zenica   = ST_GeomFromText('POINT(17.907743 44.203438)');
set @sarajevo = ST_GeomFromText('POINT(18.413076 43.856258)');
SELECT ST_Distance_Sphere(@zenica, @sarajevo);
