Created December 15, 2021 19:40 — forked from statickidz/nearby-coordinates.sql

Ordering with SQL by nearest latitude & longitude coordinates (MySQL & SQLite)

	---
	METHOD 1

	This should roughly sort the items on distance in MySQL, and should work in SQLite.
	If you need to sort them preciser, you could try using the Pythagorean theorem (a^2 + b^2 = c^2) to get the exact distance.
	---
	SELECT *
	FROM table
	ORDER BY ((lat-$user_lat)(lat-$user_lat)) + ((lng - $user_lng)(lng - $user_lng)) ASC
