MariaDB starting with 10.2.4

ST_GeomFromGeoJSON was added in MariaDB 10.2.4


ST_GeomFromGeoJSON(g[, option])


Given a GeoJSON input g, returns a geometry object. The option specifies what to do if g contains geometries with coordinate dimensions higher than 2.

1Return an error (the default)
2 - 4The document is accepted, but the coordinates for higher coordinate dimensions are stripped off.

Note that this function did not work correctly before MariaDB 10.2.8 - see MDEV-12180.


SET @j = '{ "type": "Point", "coordinates": [5.3, 15.0]}';

SELECT ST_AsText(ST_GeomFromGeoJSON(@j));
| ST_AsText(ST_GeomFromGeoJSON(@j)) |
| POINT(5.3 15)                     |
