(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)

OTHER:
1) The Delphi docs say that double-clicking on TSQLConnection
component, that a dialog should open. This does NOT happen.
1) I don't know if the docs are wrong or the component is not working
If you need any other info, please let me know.
Again, Alex, thank you for all your hard work.
