Querying tables from Sybase and Oracle at the same time

[Ho, Tony]

Hi guys
I was wondering if you could help me.
I have table A in Oracle and table B in Sybase
I want to use an SQL in my perl code to select from both tables A and B as
follows:
 
select A.first_name, B.last_name
from tables A, B
where A.account = B.account
 
Is it possible to use DBI to do this ?
If so, how can I go about it ?
 
I would be most grateful if you could let me know.
Cheers
Tony
