Gets the unextended display name of a specified database object.
This method is useful in a MultiSite environment. It parses an extended name and returns the unextended name. An extended name contains a site-specific extension that makes it unique among all names in a MultiSite environment. An unextended name is known to be unique only to its site. If the specified name is already an unextended name, then no error will occur, and you will just receive the same name. If the specified name is not a valid name, you will receive an empty string.
