我备份了一个数据库:
BACKUP DATABASE MyDatabase
TO DISK = 'MyDatabase.bak'
WITH INIT --overwrite existing
然后试图恢复它:
RESTORE DATABASE MyDatabase
FROM DISK = 'MyDatabase.bak'
WITH REPLACE --force restore over specified database
现在数据库处于还原状态。
有些人推测，这是因为备份中没有日志文件，需要使用以下方法前滚:
RESTORE DATABASE MyDatabase
WITH RECOVERY
当然，这是行不通的:
Msg 4333, Level 16, State 1, Line 1
The database cannot be recovered because the log was not restored.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
在灾难性的情况下，你想要的是一个无法工作的恢复。
备份包含数据文件和日志文件:
RESTORE FILELISTONLY
FROM DISK = 'MyDatabase.bak'
Logical Name PhysicalName
============= ===============
MyDatabase C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase.mdf
MyDatabase_log C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase_log.LDF
这个方法奏效了:

我有一个情况，我的数据库显示恢复状态，我不能运行任何查询，不能与我们的软件连接。
为了摆脱这种情况，我所做的是:
停止windows服务中的所有SQL相关服务。
我打开了数据文件夹，其中Ldf和Mdf文件驻留在SQL目录中，通常是这样的:
“C: \程序文件 ***********\ 该软件\数据
然后我复制了数据库的Ldf和Mdf文件:
(数据库名称)。MDF和[db name]_log.ldf
我把这两个文件都复制到另一个文件夹。
Then I started all the SQL related services (in step 1) again from windows services.
Started my MS SQL Management studio with normal login.
Right click on the culprit database and hit DELETE (to delete the database at all).
All the LDF and MDF files related to this database have gone from DATA folder (mentioned in step 2).
Created a new database with the same name (same name of the one I deleted in step 6 - the culprit database).
Then [database name]->right click -> tasks -> Take Offline.
I then Copied both the files (from step 3) back to the DATA folder (step 2).
[database name]->right click -> tasks -> Bring Online.
执行RESTORE DATABASE/RESTORE LOG命令时，默认使用WITH RECOVERY选项。如果你被困在“恢复”过程中，你可以通过执行以下命令将数据库恢复到在线状态:
RESTORE DATABASE YourDB WITH RECOVERY
GO
如果需要恢复多个文件，CLI命令分别需要WITH NORECOVERY和WITH RECOVERY -只有命令中的最后一个文件需要WITH RECOVERY才能使数据库恢复在线:
RESTORE DATABASE YourDB FROM DISK = 'Z:\YourDB.bak'
WITH NORECOVERY
GO
RESTORE LOG YourDB FROM DISK = 'Z:\YourDB.trn'
WITH RECOVERY
GO
你也可以使用SQL Server Management Studio向导:
也有虚拟恢复过程，但你必须使用第三方解决方案。通常，您可以使用数据库备份作为实时在线数据库。ApexSQL和Idera都有自己的解决方案。由SQL Hammer审查关于ApexSQL恢复。如果要处理大量备份，虚拟恢复是一个很好的解决方案。恢复过程要快得多，还可以节省磁盘驱动器上的大量空间。你可以看看这里的信息图进行一些比较。
I had a similar issue with restoring using SQL Management Studio. I tried to restore a backup of the database to a new one with a different name. At first this failed and after fixing the new database's file names it was successfully performed - in any case the issue I'm describing re-occurred even if I got this right from the first time. So, after the restoration, the original database remained with a (Restoring...) next to its name. Considering the answers of the forum above (Bhusan's) I tried running in the query editor on the side the following:
RESTORE DATABASE "[NAME_OF_DATABASE_STUCK_IN_RESTORING_STATE]"
这解决了问题。一开始我遇到了麻烦，因为数据库名称包含特殊字符。我通过在周围添加双引号来解决这个问题-单引号将不起作用，给出“错误的语法接近……”错误。
这是我尝试解决这个问题(数据库处于恢复状态)的最小解决方案，我希望它可以应用到更多的情况。
