I'm doing some work with part diagrams and server-side image maps.
I want to store single point coordinates (x,y) for reference numbers in a
table looking like:
reference_number text,
x int,
y int
My question is: How can I find the *nearest* match of some clicked on
coordinates without specifying some arbitrary distance from the stored
point?
The more I think about this the more I am realizing it is probally not
that hard, I just can't seem to grasp the answer right now.
Thanks,
Ryan
