Answer 12

I made a more effective way, in my case AttractivePlace is just place

ALTER TABLE cities
ADD place VARCHAR(128);

UPDATE cities
SET place =
CASE
WHEN name = 'Lisbon' THEN 'Belem Tower'
WHEN name = 'Madrid' THEN 'Plaza Mayor'
WHEN name = 'Paris' THEN 'Eiffel Tower'
END
;

SELECT * FROM cities;
