還原的資料庫 '%2' 的檔案 '%1' 停留在無用狀態，因為資料庫正在使用簡單復原模式，且檔案標示為讀寫存取。因此，分次還原只能復原唯讀檔案。

The file '%1' of restored database '%2' is being left in the defunct state because the database is using the simple recovery model and the file is marked for read-write access. Therefore, only read-only files can be recovered by piecemeal restore.
