### Public Instance methods

connect(server)

Connect to the database. In addition to the usual database options, the following options have an effect:

- :command_timeout - Sets the time in seconds to wait while attempting to execute a command before cancelling the attempt and generating an error. Specifically, it sets the ADO CommandTimeout property. If this property is not set, the default of 30 seconds is used.
- :conn_string - The full ADO connection string. If this is provided, the usual options are ignored.
- :provider - Sets the Provider of this ADO connection (for example, "SQLOLEDB")
