This is not necessarily SQL Specific, but it will impact my MySQL
application.
Using the zip code, how can you determine what's in a (say) 50 mile radius.
In other words, if I'm looking for schools within a 50 mile radius of my
location (Zip Code 33881), How can I determine this by the zip code? I have
seen lots of search engines that do this, but don't know how they determine
the distance. I figured that I can use the first 4 digits as a match, then
the first 3 digits which will be a little further away, but I don't know how
accurate that would be. Does anyone have any ideas?
Thanks,
Jesse
