Обсуждение: Possible to create a *really* virtual table ?

Hello !

Is it possible to create a virtual table, NOT a view ?

For example :

SELECT *
FROM
(VALUES ('orange', 'orange'), ('apple', 'red'),
('banana', 'yellow'))
AS Fruits_And_Colors(fruit, color);

I.e. to do a request on a non-real table ?

I want to have the following virtual table :

TABLE b
id   |   b
------------
1    |   't'
2    |   'f'

Is it possible in PostgreSQL ?

Thanks a lot for any help

Ok I found the answer, it is possible !

SELECT text 'a' AS "Text" UNION SELECT 'b';
