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
Below is the required implementation:
SQL
declare-- declare variable x, y -- and z of datatype numberx number(5); y number(5); z number(7); begin-- Here we Assigning 10 into xx:=10; -- Assigning 20 into xy:=20; -- Assigning sum of x and y into zz:=x+y; -- Print the Resultdbms_output.put_line('Sum is '||z); end; / -- Program End |
Output :
Sum is 30
