explain why the database system would not allow a tuple to be inserted into the database through this view

Andrej [43]

For the view of Exercise 4.18, explain why the database system would not allow a tuple to be inserted into the database through this view.
For reference
For the database of Figure 4.12, write a query to find the ID of each employee with no manager. Note that an employee may simply have no manager listed or may have a null manager. Write your query using an outer join and then write it again using no outer join at all.
OUTER JOIN
select e.ID from employee e left outer join manages m on e.ID = m.ID
where m.manager_id is null;
NO OUTER
select e.ID from employee e where e.ID not in (select m.ID from manages m) or e.ID in (select m.ID from manages m where m.manager_id is null);

The user will input a three digit number

zlopas [31]

import java.util.Scanner;

public class U1_L5_Activity_One {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Please enter a two digit number: ");

int x = scan.nextInt();

System.out.println("Here are the digits:");

System.out.println(x/100);

System.out.println((x/10)%10); //Just divide the result by 10 and find the remainder

System.out.println(x%10);

}

//Or, you can do that way:

import java.util.Scanner;

public class U1_L5_Activity_One {

public static void main(String[] args) {

Scanner scan = new Scanner(System.in);

System.out.print("Please enter a two digit number: ");

String[] x = scan.nextLine().split(""); //We need it to be a string array, to split the values after "", that is, after each symbol(number)

System.out.println("Here are the digits:");

for(int i = 0; i<x.length; i++) {

System.out.println(Integer.parseInt(x[i])); //Converting the string into int, as you want

}
