Table: Student Table: Department
Roll_no is the primary key of the Student table, Dept_id is the primary key of the Department table and Student. Dept_id is a foreign key from Department. Dept_id
What will happen if we try to execute the following two SQL statements?
(i) update Student set Dept_id = Null where Roll_on = 1
(ii) update Department set Dept_id = Null where Dept_id = 1
