The question:
Display the names of the workers that live in the same cities as their chef.

Table one: Werknemer
columnes: wnr (workersnumber), wnaam (workersname), chef (wnr of the chefs)

Table two: Prive
columnes: wnr (workersnumber), wnaam (workersname), city (names of the city)

What should my OUTER JOIN LOOK LIKE?

SELECT w.wnaam
FROM Werknemer w
JOIN Prive p1
ON p1.wnr = w.wnr
JOIN Prive p2
ON p2.wnr = w.chef
WHERE p1.city = p2.city

Thanks for all the replies!

This was the anwers:

SELECT A.wnaam AS chef, B.wnaam AS werknemer
FROM Werknemer A INNER JOIN Werknemer B
ON (A.wnr = B.chef)
INNER JOIN Prive C
ON (A.wnr = C.wnr)
INNER JOIN Prive D
ON (B.wnr = D.wnr AND C.woonplaats = D.woonplaats)
ORDER BY chef
