The eassiest way is to use a View like this:
CREATE VIEW Db2.student AS
SELECT id, firstname, lastname
FROM Db1.student;
If you want to filter some content in the Db2 view you could add some filters to the view creation. For example:
CREATE VIEW Db2.student AS
SELECT id, firstname, lastname
FROM Db1.student
WHERE Db1.student.status = 1;
I hope it works for you.
