You'll want to update from the results of another query. For performance it's best to do within the context of an indexed column, so you end up with some ugliness. WITH sums AS ( SELECT a.cartodb_id AS cartodb_id, Count(*) as count, sum(a.popn) as popn FROM populated_places_esp a JOIN populated_places_esp b ON ST_DWithin( ...

You need to pass: Input features - highway; Nearest features - points and set radius; than optionally you can mark location and angle. After ...
