CREATE TEMPORARY TABLE fruits (id SERIAL, name TEXT);
INSERT INTO fruits VALUES (DEFAULT, 'banana');
INSERT INTO fruits VALUES (DEFAULT, 'apple');
CREATE TEMPORARY TABLE food (id SERIAL, name TEXT);
INSERT INTO food VALUES (DEFAULT, 'apple');
INSERT INTO food VALUES (DEFAULT, 'spinach');
SELECT name, CASE WHEN name = ANY (SELECT name FROM fruits)
THEN 'yes'
ELSE 'no'
END AS fruit
FROM food;
