Thanks for your reply. I guess what I'm asking is whether I can use the phpMyAdmin instance that is already installed on my Dreamhost account to connect to an external database host.
Specifically, can I go to mydatabase.mydomainname.com, hosted at Dreamhost, log in, and from phpMyAdmin connect to a different SQL host (not hosted at Dreamhost)?
I'm trying to avoid having to install phpMyAdmin myself (I'm lazy!)
Thanks for any ideas.
