Hi Folks -
I'm working on a global weather database for a client and have hit an issue
which I'm sure has been solved before. Unfortunately, the site search doesn't
pull up anything.
Essentially, I've got two tables, one with city/county/lat/long and another
with lat/long/weather data.
None of the lat/longs in the two tables match up directly, so I can't do a
simple join of the two tables. I need to join on closest proximity on the
lat/long fields.
Any suggestions? It seems to me this will be pretty expensive on CPU resources
unless there's a really elegant trick uncovered.
