public function STDistance( other : SqlGeography ) : SqlDouble
Is another geography instance from which to measure the distance between the instance on which STDistance is invoked. If an empty set is specified, STDistance will return null.
Returns null if the spatial reference IDs (SRIDs) of the SqlGeography instances do not match.If this method is used to determine distance between antipodal points, or consecutive points on opposite sides of the globe, as in the distance between POINT (0 0) and POINT (180 0), this method will return null.
