Almost unbelievably, MariaDB lacks this ST_Distance_Sphere (MDEV-13467).

Find their support matrix here.

And it's not just that either, it also lacks ST_GeoHash that MySQL has.

Answer 2

I think that's it ST_DISTANCE https://mariadb.com/kb/en/library/st_distance/

Answer 3

For those who still need the function in MariaDB, you can create the function based on the formula

    CREATE FUNCTION `st_distance_sphere`(`pt1` POINT, `pt2` POINT) RETURNS 
    decimal(10,2)
    BEGIN
    return 6371000 * 2 * ASIN(SQRT(
       POWER(SIN((ST_Y(pt2) - ST_Y(pt1)) * pi()/180 / 2),
       2) + COS(ST_Y(pt1) * pi()/180 ) * COS(ST_Y(pt2) *
       pi()/180) * POWER(SIN((ST_X(pt2) - ST_X(pt1)) *
       pi()/180 / 2), 2) ));
    END

That blog discusses multiple ways of "finding nearest" on the globe in MySQL/MariaDB. As part of that discussion, I developed that Stored Function.
