Calculating distance using MySQL

Calculating distance using MySQL” is a very useful blog post for everyone who works with geographical location data and MySQL. It shows a simple example of how to calculate the distance between two coordinates on a sphere (Earth in particular) within the MySQL itself.

SELECT ST_Distance_Sphere(
    point(-87.6770458, 41.9631174),
    point(-73.9898293, 40.7628267)

The above will return 1148978.6738241839, which is the distance between the two points in meters.

This functionality is available since MySQL 5.7. Have a look at the documentation of the spacial convenience functions.

MariaDB has similar functionality, but with a slightly different function names. Use ST_DISTANCE() instead of ST_Distance_Sphere(). Have a look at this blog post for more details.
