Generally, you use schemas for this. Schemas are just namespaces
inside the one database.
I have read something about schemas and I have simply created an own
schema for every database with the same name, but it still does not
work. Is there anything plain and simple?
SELECT f.one, b.two
FROM
one_schema.foo AS f
JOIN
other_schema.bar AS b
ON (f.id = b.foo_id)
WHERE...
Cheers,
