Cascading Referential Integrity Constraints: There are new ON DELETE and
ON UPDATE clauses in the REFERENCES clause of the CREATE TABLE

attempt to update a candidate key value to which existing foreign keys point.

fail with an error.
CASCADE :-CASCADE specifies that all the rows with foreign
keys pointing to the deleted/updated row are also deleted/updated.
