    Talking Pk

    Is this statement true: Records are never deleted from the parent tables, and primary keys are never updated in the parent tables.

    True that the PK itself should generally not ever be updated, but there is no reason whatsoever it can't be deleted. How does on delete cascade work for FKs?
