備註
The NamedFileGroup element contains the definition of one filegroup. Every database has a PRIMARY filegroup, and if you define application database properties, you must have a PRIMARY filegroup. You can have additional filegroups to group additional data files together for administrative, data allocation, and placement purposes. For more information about files and filegroups, see 瞭解檔案及檔案群組.
If you want to alter the application database after creating the application, use the Microsoft SQL Server tools, such as SQL Server Management Studio.
