Sum Of Two Numbers in PL/SQL


Prerequisite PL/SQL introduction

In PL/SQL code groups of commands are arranged within a block. A block group related declarations or statements.
In declare part, we declare variables and between begin and end part, we perform the operations.

Here, first, we take three variables x, y, and z and assign the value in x and y and after addition of both the numbers, we assign the resultant value to z and print z.

Examples:

Input : 15 25
Output : 40
Input : 250 400
Output : 650

y number(5);            
z number(7);        
  
begin
  
-- Here we Assigning 10 into x
x:=10;                 
  
-- Assigning 20 into x
y:=20;                 
  
-- Assigning sum of x and y into z
z:=x+y;                 
  
// Print the Result
dbms_output.put_line('Sum is '||z); 
end
/                         
-- Program End
