PL/SQL Control Statement Exercises: Using loop with CONTINUE statement

PL/SQL Control Statement: Exercise-21 with Solution

Write a program in PL/SQL using loop with CONTINUE statement.

Sample Solution:

PL/SQL Code:

DECLARE
  n NUMBER := 0;
BEGIN
  LOOP 
    DBMS_OUTPUT.PUT_LINE ('Inside the loop:  n = ' || TO_CHAR(n));
    n := n + 1;
    IF n < 5 THEN
      CONTINUE;
    END IF;
    DBMS_OUTPUT.PUT_LINE
      ('Inside the loop, after CONTINUE:  n = ' || TO_CHAR(n));
    EXIT WHEN n = 7;
  END LOOP;
 
  DBMS_OUTPUT.PUT_LINE ('When out from the loop:  n = ' || TO_CHAR(n));
END;
/

Flowchart:

Sample Output:

SQL> /
Inside the loop:  n = 0
Inside the loop:  n = 1
Inside the loop:  n = 2
Inside the loop:  n = 3
Inside the loop:  n = 4
Inside the loop, after CONTINUE:  n = 5
Inside the loop:  n = 5
Inside the loop, after CONTINUE:  n = 6
Inside the loop:  n = 6
Inside the loop, after CONTINUE:  n = 7
When out from the loop:  n = 7
