Oracle PL/SQL - Parameter Named Notation

Introduction

To pass only the last parameter, use named notation, where you explicitly define which actual parameter corresponds to each formal one.

hello,people!
hello,world...
hello,people...

The => operator indicates explicit pairs.

Because you're naming parameters explicitly, you don't need to use any specific order.
