SQL & PL/SQL

Hi all .
Is there a way to create mview that acts like a session? i'll explain :
i'm connecting to a session (let's call this session , session 1 )

sqlplus naama/naama@passwd 
select emp_id   , emp_name  from emp;
emp_id      emp_name 
-----------  -----------------
1           Naama 
2           Alice
3           Alexandra 

update emp set emp_name = 'ROY' where emp_id  = 1 ;

select emp_id   , emp_name  from emp;

emp_id      emp_name 
-----------  -----------------
1           ROY 
2           Alice
3           Alexandra 

Because i'm in the same session , when i'm doing an update , without a commit i will still see the data after the update (=ROY and not Naama ) .
Is there Any mview that i can declare that will be refreshed when i'm making a changes to the base table , means mview that will acts as if it was a select
inside the same session ,
Please Your Help
