Hi,

while being logged on to one (assuming that sufficient priveleges are
granted)? For example I'm connected to db_1 and I try to execute query on
db_2 like this

No, not "natively". That is, if you're using, for example, the BDE, you can
do this, but it will join the tables at the client side.

So, the short answer is: no.
