SQL Server doesn't support an exponent operator (^), so you'll need to use either the POWER or EXP function instead. Also, some of your parentheses seemed to be off, so try this:
2 * asin(sqrt( power(sin((lat1-lat2)/2),2) + cos(lat1) * cos(lat2) * power(sin((lon1-lon2)/2),2) ) ) In the future, you may want to try the HoF SQL mailing list for a faster response.
