I have 2 point layers. One is containing old address points and the second is new address points. They don't have any unique attributes which I could join them with. So I've made a 10 meter buffer around the new points to find the old ones closest to them (they have similar coordinates) and now I have to check if the new addresses are correct. Is there any chance that I can make a query which will check if the given address in buffer around the new address points is the same as the given address in the old points which I've found in buffer?
