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.
