OK so you are saying to enter into Terminal, either: ssh -L 3307:localhost:3306 remote.db.server , OR enter into Terminal:  
ssh -L 3307:remote.db.server:3306 remote.db.server and substitute in my remote server address for "remote.db.server" 

Once I do that, what should I enter into the OpenOffice Calc Spreadsheet Application Dialog box, in order to get the OpenOffice Calc local applicationwhich resides on my desktop
machine to read the remote database?
