open a new database connection
Open( filename, create, readonly )
URI file name
(optional) create database if it does not exist, default is true
(optional) open database in read-only mode, default is false
The Open command opens a new database connection.
If the filename is :memory:, then a private, temporary in-memory database is created for the connection. This in-memory database will vanish when the database connection is closed.
If the filename is an empty string, then a private, temporary on-disk database will be created. This private database will be automatically deleted as soon as the database connection is closed.
The Open command can open an existing database from Workbook if the filename is a valid Workbook URI.
