※ 引述《qrtt1 (愚人)》之銘言：
: FROM DISK = N'D:\MyDB\MyDB_backup_200711151513.bak' WITH REPLACE
: 做了完整備份的回復, 接著使用
: RESTORE DATABASE [MyDB]
: FROM DISK = N'D:\MyDB\MyDB_backup_200712140155.bak' WITH NORECOVERY
: 執行差異回復時出現了錯誤訊息
後來我發現改成
RESTORE DATABASE [MyDB]
FROM DISK = N'D:\MyDB\MyDB_backup_FULL.bak' WITH NORECOVERY, REPLACE
接著
RESTORE DATABASE [MyDB]
FROM DISK = N'D:\MyDB\MyDB_backup_DIFF.bak' WITH NORECOVERY
就可以了.
不過我對於 RECOVERY 與 NORECOVERY 的意義不很了解

Comparison of RECOVERY and NORECOVERY
Roll back is controlled by the RESTORE statement through the [ RECOVERY |
NORECOVERY ] options:
* NORECOVERY specifies that roll back not occur. This allows roll forward
to continue with the next statement in the sequence.
In this case, the restore sequence can restore other backups and roll
them forward.
* RECOVERY (the default) indicates that roll back should be performed
after roll forward is completed for the current backup.
Recovering the database requires that the entire set of data being
restored (the roll forward set) is consistent with the database. If the roll
forward set has not been rolled forward far enough to be consistent with the
database and RECOVERY is specified, the Database Engine issues an error.
不知道我是不是要在最後一個 DIFF 的備份使用 RECOVERY ?
