  A foreign key with cascade delete can be created using either a CREATE TABLE statement or an ALTER TABLE statement.[1]

  if you delete the primary key constraint from a table (the parent table) that is referenced in a foreign key constraint in another table (the child table), then the foreign key constraint in the child table is also deleted through a cascading delete mechanism.[2]
