Specifies a database name for a connection; it can be used instead of specifying the database name in after the subprotocol.
If the database name is specified both in the URL (as a subname) and as an attribute, the database name set as the subname has priority. For example, the following database connection URL connects to toursDB:
Allowing the database name to be set as an attribute allows the getPropertyInfo method to return a list of choices for the database name based on the set of databases known to Derby. For more information, see java.sql.Driver.getPropertyInfo.
You can combine this attribute with all other attributes.
