Don't attempt to get that exact output I wrote a stored function in MySQL but it calculates just 1 for each row in select query. you'd have a column in your table of type GEOGRAPHY which would be populated with a geospatial representation of the coordinates (check out the MSDN reference linked above for examples).

I'm on SQL Server 2014. In addition to the previous answers, here is a way to calculate the distance inside a SELECT: CREATE FUNCTION Get_Distance A minor scale definition: am I missing something? Is there any way to do that with mysql. TSQL: Calculating distance between two points (Latitude, @RickJames :-) thanks for pointing this out! One disadvantage of the longitude/latitude representation is that you need to be careful about the edge conditions near the poles and near +/- 180 degrees of longitude. With the advent of GPS and other widely available global location data, there is an increasing need to be able to accurately calculate the distance between two points over the earth's surface, from latitudes and longitudes. It only takes a minute to sign up. p1_latitude: real The latitude value in degrees of the first geospatial coordinate. As you're using SQL 2008 or later, I'd recommend checking out the GEOGRAPHY data type. It is strongly recommended that earthdistance and cube be installed in the same schema, and that that schema be one for which CREATE privilege has not been and will not be granted to any untrusted users. In SQL Server how can I return values in one table that are less than 20 miles from a coordinate? Can anyone help me with that. All that you need is to add an extra column odometer where the total mileage should be written each time you get a new lat-lon point. Since you're using SQL Server 2008, you have the geography data type available, which is designed for exactly this kind of data: DECLARE @source Calculating distance between two points in SQL - airops.com My final code now is such simple: SET a = 0.01745329252 * lat1; SET b = You're using SRID 4326, which means that STDistance() returns distances in metres.
