Zde jsou další dvě metody, jen pro úplnost:
SELECT p.name, MAX(CASE t.phonetype WHEN 'work' THEN t.phoneno END) AS workphone, MAX(CASE t.phonetype WHEN 'home' THEN t.phoneno END) AS homephone, MAX(CASE t.phonetype WHEN 'mob' THEN t.phoneno END) AS mobilephone FROM people p INNER JOIN phones t ON p.Id = t.Id GROUP BY p.Id, p.Name
SELECT p.name, w.phoneno AS workphone, h.phoneno AS homephone, m.phoneno AS mobilephone FROM people p LEFT JOIN phones w ON p.Id = w.Id AND w.phonetype = 'work' LEFT JOIN phones h ON p.Id = h.Id AND h.phonetype = 'home' LEFT JOIN phones m ON p.Id = m.Id AND m.phonetype = 'mob'
