SQL & PL/SQL

Hello Guys,

Can you tell me what is the use of view when we create with FORCE option if underliying table is not available ?

CREATE OR REPLACE FORCE VIEW MY_VIEW AS SELECT * FROM EMP;

Now View My_View will be created even if the emp table is not available. But where we can use this view ?. What is the applicatin of My_View when we know that EMP table is not available ?.

Thanking you.
