how to create a view in oracle based on dual?

Question

i want to create this view in oracle but it doesn't work

create view view_E as
SELECT 'value 1' col from dual  UNION  
SELECT 'value 2'  from dual UNION   
SELECT 'value 3'  from dual UNION  
SELECT 'value 4'  from dual 

the select works fine and I want to create a view based on it. the equivalent of this code works on SQL server is there a rule that says you can't create a view based on select from dual thanks.
