Adding A Distance between (miles) Column in ETL
Comments

Are you looking for driving distance or as the crow flies?

Miles would be ideal, we keep zip codes of our employee's address and our shop locations and I'd like to map out where techs we retain live compared to techs that don't make it to the 90 day mark live in comparison to their home shop.
We keep full addresses of both home and shops but I figured that may be asking for too much lol

Ok, so the more I dug into this the nastier it got. But, there is a way to do it.
I found a walkthrough where a guy put together a MySQL formula for this. You'll need to find the Lat/Long values for each zip code you're wanting to use.
You can then use those with this Haversine formula:
set @orig_lat=122.4058; set @orig_lon=37.7907;set @dist=10;
SELECT *,
3956 * 2 * ASIN(SQRT( POWER(SIN((@orig_lat -
abs(
dest.lat)) * pi()/180 / 2),2) + COS(@orig_lat * pi()/180 ) * COS(
abs
(dest.lat) * pi()/180) * POWER(SIN((@orig_lon – dest.lon) * pi()/180 / 2), 2) ))
as distance
FROM hotels dest
having distance < @dist
ORDER BY distance limit 10;Here's a link to the reference:

For each of the values inside SIN an COS functions, you'll need to calculate in a prior transform before calling those. It does work from what I've tested.
Hopefully this will get you started on the right track,
