使用SQL Server 2012还原多个数据库的最佳脚本？

Question

我必须还原大约60个不同大小的SQL数据库。我在谷歌上找到了一个脚本来互相恢复所有数据库，只是从我的文件夹中按1个1个选择它。我没有那么成功，可能是因为我对SQL等不熟悉。

它可以在powershell或sql命令行中完成，我现在发现的是这样的：

RESTORE DATABASE [db1] FROM  DISK = N'C:\folder\db1.bak' WITH  FILE = 1,  NOUNLOAD,  STATS = 10
GO
RESTORE DATABASE [db2] FROM  DISK = N'C:\folder\db2.bak' WITH  FILE = 1,  NOUNLOAD,  STATS = 10
GO

因此，我要做的是从某个文件夹中获取文件名，并将“ db1.bak”等替换为我刚从文件夹中选择的名称，然后运行脚本。

我知道必须有一个更聪明的方法，或者是否有可能将许多.bak文件“加载”到SSMS中，以便程序将彼此依次运行？

Collet的脚本经过一些改编对我有用。请务必先启用xp_cmdshell。

DECLARE @FilesCmdshell TABLE (
    outputCmd NVARCHAR (255)
)   
DECLARE @FilesCmdshellCursor CURSOR 
DECLARE @FilesCmdshellOutputCmd AS NVARCHAR(255)

INSERT INTO @FilesCmdshell (outputCmd) EXEC master.sys.xp_cmdshell 'dir /B  C:\Backup\*.bak'    
SET @FilesCmdshellCursor = CURSOR FOR SELECT outputCmd FROM @FilesCmdshell

OPEN @FilesCmdshellCursor
FETCH NEXT FROM @FilesCmdshellCursor INTO @FilesCmdshellOutputCmd
WHILE @@FETCH_STATUS = 0
BEGIN   
    DECLARE @sqlRestore NVARCHAR(MAX) = 'RESTORE DATABASE [' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '] FROM  DISK = N''C:\Backup\' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '.bak'' WITH  FILE = 1,  MOVE N''' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + ''' TO N''C:\Microsoft SQL Server\SQLINSTANCE\MSSQL\DATA\' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '.mdf'',  MOVE N''' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '_log'' TO N''C:\Microsoft SQL Server\SQLINSTANCE\MSSQL\DATA\' + SUBSTRING(@FilesCmdshellOutputCmd, 0, CHARINDEX('.', @FilesCmdshellOutputCmd)) + '_log.ldf'', NOUNLOAD,  STATS = 10'
    EXEC(@sqlRestore)

    FETCH NEXT FROM @FilesCmdshellCursor INTO @FilesCmdshellOutputCmd
END

如何启用xp_cmdshell：

-- To allow advanced options to be changed.  
EXEC sp_configure 'show advanced options', 1;  
GO  
-- To update the currently configured value for advanced options.  
RECONFIGURE;  
GO  
-- To enable the feature.  
EXEC sp_configure 'xp_cmdshell', 1;  
GO  
-- To update the currently configured value for this feature.  
RECONFIGURE;  
GO
