geolocation - How do I enter an "empty" POINT() geometry value into a MySQL field of type POINT? -


i have table point geometry field. enter latitude/longitude points this:

insert table( point ) values( point( lon_value, lat_value );

sometimes not have lat/lon values enter. unable enter blank, null, or empty point() ... since point(0,0) location on globe, won't work either.

what solution here?

i use coordinates of north pole

insert table( point ) values( point(0.0000,90.0000);

if actual coordinates of pole may issue change lon value 0.0000.
