Here's a small stored procedure that does the difference from two sets of latitude/longitude.
create procedure dbo.sp_latLongDist @lat1 numeric, @long1 numeric, @lat2 numeric, @long2 numeric, @units char(2) as set nocount on ; declare @mult numeric ; if @units = 'km' set @mult = 1.852 else set @mult = 1.0 ; select sqrt(power((69.1*(@[EMAIL PROTECTED])),2)+power((69.1*(@[EMAIL PROTECTED])*cos(@lat1/57.3)),2))[EMAIL PROTECTED] as distance go And example usage: exec dbo.sp_latLongDist 34.09011, -118.4065, 42.34892, -71.04651, 'nm' ; -- Phillip Beazley Onvix -- Website Hosting, Development & E-commerce Visit http://www.onvix.com/ or call 727-578-9600. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:226018 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
