Weizman Jonathan writes "Hi,
I've developed a C function that computes the distance betwen 2 Lat/Lon on the earth.
I want to have a select function like:
Select * from Mytable where distance(@x,@y,mytable.lat,mytable.lon)<500
The problem is that i didn't find any way to use this function which lies in a DLL.
Creating the function in SQL would be difficult since there is a lot of computation.
Thanks
Jonathan" |
