Update counter

Counter columns are special, in that they can only be updated, not inserted.

Prerequisites

This example shows a count column called popularity updated by adding 2 to the current count:

UPDATE cycling.popular_count 
SET popularity = popularity + 2 
WHERE id = 6ab09bec-e68e-48d9-a5f8-97e6fb4c9b47;
