if i have this query:
SELECT * FROM books2006, books2007;


(books 2006 and 2007 have exactly the same fields.)

how can i tell if the data was retrieved from books2006 or books2007
(whitout changing anything in the databases) ?

in other words is there any way that along the information that i
retrieve from the fields (ex. author, date_published, isbn) that i
also get the name of the database from which i retrieved the
information?

thank you very much,

GD
