CREATE TABLE emp_temp AS
SELECT employee_id, first_name, last_name,email
FROM employees;
DECLARE
z_emp_id NUMBER:=&employee_id;
BEGIN
UPDATE emp_temp
SET email = 'not available'
WHERE employee_id = z_emp_id;
IF SQL%NOTFOUND THEN
DBMS_OUTPUT.PUT_LINE ('No employee of ID '|| z_emp_id||' is found.');
ELSE
DBMS_OUTPUT.PUT_LINE (
'Update succeeded for employee_id: ' || z_emp_id
);
END IF;
END;
