calculate distance

Question

i am designing a recruitment database, and i need it to perform several tasks that all involve integrating a way of calculating distance:

1) calculate the distance t

Answer 1

Just a thought: If your clients and candidates live in a very limited area, I would use a rectangular map and enter x and y values for all cities in that area in a database.

Due to the pythagorean theorem, you can say:

distance² = (x-value client - x-value candidate)² + (y-value client - y-value candidate)²
