Select objects within radius using longitude and latitude

Question

I wonder how I can create a query and select objects that are located within a radius of 50 km.

The information I can use is Longitude and latitude for every object. I would like to set my own location in the query and calculate the objects distance to my position based on its coordinates.

You need to download some geo location database which contains data based on lats and longs. — Nilesh, Sep 16 '13 at 14:06

Assuming you're using a geography type, which you should be, use STDistance - see http://technet.microsoft.com/en-us/library/bb933808.aspx

select *  
from yourtable
where place.STDistance(@myposition)<50000
