如果您想从备份文件恢复SQL Server数据库，可以使用以下脚本:

RESTORE DATABASE [MyDatabase] -- which database to restore
FROM DISK = N'X:\MyDatabase.bak' -- location of the database backup
WITH 
    FILE = 1, -- restore from a backup file
    -- declare where the file groups should be located (can be more than two)
    MOVE N'MyDatabase_Data' TO N'D:\SSDPATH\MyDatabase.mdf',
    MOVE N'MyDatabase_Log' TO N'E:\HDDPATH\MyDatabase.ldf',
    -- Tape option; only relevant if you backup from magnetic tape
    NOUNLOAD,
    -- brings the database online after the database got restored
    -- use this option when you don't want to restore incremental backups
    -- use NORECOVERY when you want to restore differential and incremental backup files
    RECOVERY,
    -- replace existing database with the backup 
    -- deletes the existing database
    REPLACE, 
    -- print log message for every 1 percent of restore
    STATS = 1;

我已经得到了MyDbName(恢复…)情况，因为SQL Express许可限制。

在日志文件中，我发现了这个:

创建数据库或更改数据库失败，因为结果 累积数据库大小将超过您的许可限制10240 MB 每个数据库。

因此，如果您试图恢复一个更大的数据库，您需要将SQL Express服务器切换到开发人员版本。

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。

我知道为什么了。

如果发出RESTORE DATABASE命令的客户端在恢复期间断开连接，则恢复将卡住。

奇怪的是，当客户机连接告诉服务器恢复数据库时，除非客户机一直保持连接，否则服务器不会完成恢复。

所有基于WITH RECOVERY的选项都不适合我。

所做的是做完整的恢复从管理工作室。

USE [master]
RESTORE DATABASE Sales_SSD
FROM  DISK = N'D:\databaseBackups02\Daily_Sales_20150309_0941.bak' 
WITH  FILE = 1,  
MOVE N'Sales_Data' TO N'C:\Data\SSD\Sales.mdf',  
MOVE N'Sales_Log' TO N'C:\Data\SSD\Sales_1.ldf',  
NOUNLOAD,  REPLACE,  STATS = 5

RESTORE DATABASE {DatabaseName}
   FROM DISK = '{databasename}.bak'
   WITH REPLACE, RECOVERY
