Query Oracle Dual via Access Link Table?

Hi everyone,

I am working on a project using Access as the frontend of a Oracle
database. I'd like to use the Dual table in Oracle so I made a link
table in Access for the Dual. However, it doesn't work when I run the
following queries:

SELECT sysdate
FROM dual;
(dual is the link table in Access)

or

SELECT col_1
FROM dual

Why is that? Is there any way to accomplish what I want? Thx.
