database links



Can someone show me how I might be able to connect to two separate
databases, and create a query from the two? I understand in Oracle this is
referred to as "database links" but is there a more general way to do this
(i.e. will work with, say, mysql and other DBs?) I want to comapre a field
that is present in two separate files on two seperat databases. Thanks, Ike
