To retrieve a list of locations within a certain distance (e.g., 5 kilometers) from a given latitude-longitude location using MySQL's spatial features, you can use the Haversine formula, which calculates distances on the Earth's surface based on latitude and longitude. Here's how you can do it step by step:
- Create a Spatial Table:
- You need to have a spatial-enabled table where you store the latitude and longitude coordinates for each location. You can create a table with a
POINT
column for this purpose. For example:
CREATE TABLE locations ( id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255), coordinates POINT );
- You need to have a spatial-enabled table where you store the latitude and longitude coordinates for each location. You can create a table with a
