Distance between zipcodes

568915Aug 7 2007 — edited Aug 8 2007
Want to find distance between two zipcodes that have their latitude and longitude stored in a table.

The table is as follows

CREATE TABLE distance (zipcode VARCHAR2, LNG NUMBER, LAT NUMBER)

I couldn't come up with a calculation or understand the mathematical calculation on line.. Can you help me with some stored procedure or straight query that will do..?

Thanks
