Mengandalkan trik numerik (di mana jumlah tautan orang tua-anak =jumlah anak, orang tua itu terhubung ke semua anak):
SELECT Parent.ParentID, COUNT(*)
FROM Parent
INNER JOIN ChildParent
ON ChildParent.ParentID = Parent.ParentID
INNER JOIN Child
ON ChildParent.ChildID = Child.ChildID
WHERE <ChildFilterCriteria>
GROUP BY Parent.ParentID
HAVING COUNT(*) = (
SELECT COUNT(Child.ChildID)
FROM Child WHERE <ChildFilterCriteria>
)
