Null driver doesn't support any database, it is only included into distribution for testing purposes and as a driver skeleton.
Null driver doesn't really use any options, but when an attempt to connect to engine is done it prints out values of some.
By this option an internal name of SQL database is set (fake for Null driver).
A host (FQDN) on which server reside (fake for Null driver).
A password used when connecting to engine and selecting database (fake for Null driver).
A user name, passed to database when connecting and selecting database (fake for Null driver).
Null driver is written by Andrew Maltsev ( am@amsoft.ru).
