Print all odd numbers and their sum from 1 to n in PL/SQL

In this problem, we are given a number n and we have to print all odd numbers from 1 to n and also print the sum of numbers from 1 to n in PL/SQL.

PL/SQL is a procedural language extension to SQL. The code is a sequence of instructions that are ground in a block with all related declarations and instructions.

Let’s see an example of our problem −

Input: 7
Output: odd numbers are: 1, 3, 5, 7
Sum of odd numbers is 16

To solve this problem, we will take a number and initialize it to 1 and a sum variable with initial value 0. And we will increase the number by 2 and add into the sum variable until its value is less than or equal to n.

Example

DECLARE
   number NUMBER(3) := 1;
   sumvar NUMBER(4) := 0;

BEGIN
   dbms_output.Put_line('The odd numbers are : ');
      WHILE num <= 7 LOOP
         dbms_output.Put_line(number);
         sumvar := sumvar+num;
         num := num + 2;
      END LOOP;
dbms_output.Put_line('Sum of odd numbers is '|| sum1);
END;

Output

The odd numbers are −

1
3
5
7
Sum of odd numbers is 16
