Let’s say I get the user to pick long and lat on map. I have database with following columns:
zip
state
latitude
longitude
city
full_state
How do I retrieve the closest match for long and lat with hibernate HQL query?
One simple thing that you could do, is write your query so that you search for anything within a set range of from a given latitude and longitude. For example you could search for anything where:
latitude<(latitude+<your boundary>)
and latitude>(latitude-<your boundary>)
and longitude<(longitude+<your boundary>)
and longitude>(longitude-<your boundary>)
I think 1 degree of latitude or longitude is about about 69.11 miles. so to find anything within 50 miles set your boundary to be around 0.8
