Cascading updates refers to child rows being automatically deleted when a parent row is deleted.
Answer: B
Correct answer: False
That describes cascading deletions. Cascading updates propagate a change in the parent’s primary key to the foreign key values referring to it. The two are separate options and are often set differently - cascading updates being harmless with a stable key, cascading deletions being a decision about whether children should survive their parent.
