PL/SQL Control Statement Exercises: Using nested loop with EXIT WHEN statement

PL/SQL Control Statement: Exercise-20 with Solution

Write a program in PL/SQL using nested loop with EXIT WHEN statement.

Sample Solution:

PL/SQL Code:

DECLARE
  m PLS_INTEGER := 0;
  n PLS_INTEGER := 0;
 
BEGIN
  LOOP
    m := m + 1;
    DBMS_OUTPUT.PUT_LINE ('The value of m = ' || m);
    
    LOOP
      n := n + 1;
      DBMS_OUTPUT.PUT_LINE ('The value of n = ' || n);
      EXIT WHEN (n > 4);
    END LOOP;
 
    DBMS_OUTPUT.PUT_LINE ('Exited inner loop');
 
    EXIT WHEN (m > 3);
  END LOOP;
 
  DBMS_OUTPUT.PUT_LINE ('Exited outer loop');
END;
/

Flowchart:

Sample Output:

The value of m = 1
The value of n = 1
The value of n = 2
The value of n = 3
The value of n = 4
The value of n = 5
Exited inner loop
The value of m = 2
The value of n = 6
Exited inner loop
The value of m = 3
The value of n = 7
Exited inner loop
The value of m = 4
The value of n = 8
Exited inner loop
Exited outer loop
