在SQL Server 2008R2，我試圖恢復位於一個文件夾中的多個數據庫/ BAK文件，使用這裏給出一個SQL查詢 - http://www.karaszi.com/sqlserver/code/sp_RestoreFromAllFilesInDirectory_2008sp1.txt需要幫助恢復多個數據庫/ BAK文件從一個文件夾
它， 'd：\ Mydatabasesdirectory \'， 'C：\ MylogDirectory \'： -
exec sp_RestoreFromAllFilesInDirectory 'C:\Mybakfiles\',
'D:\Mydatabasesdirectory\' ,
'C:\MylogDirectory\'
夾invloved - '\ Mybakfiles \ C' 使用存儲過程像這樣，對於其中碼在最後給出
你應該知道pat h到第一個文件夾。第二個和第三個可以通過查詢或SSMS找到 。有關查詢，請參閱alexaza的答案 - What is the most efficient way to restore multiple databases in SQL 2008。我還在最後提出了他的問題。
我複製了我所有的BAK文件 - C：\ Program Files文件\ Microsoft SQL Server的\ MSSQL10_50.SS2008 \ MSSQL \備份\
然後，我進入執行如下的SP -
exec sp_RestoreFromAllFilesInDirectory 'C:\Program Files\
Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\',
'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL
\DATA\' , 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\
MSSQL\DATA\'
，得到了下面的示例輸出 -
RESTORE DATABASE AdventureWorksDW FROM DISK = 'C:\Program Files\
Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\AdventureWorksDW.bak'
WITH MOVE 'AdventureWorksDW_Data' TO 'C:\Program Files\Microsoft SQL
Server\MSSQL10_50.SS2008\MSSQL\DATA\AdventureWorksDW_Data.mdf', MOVE
'AdventureWorksDW_Log' TO 'C:\Program Files\Microsoft SQL Server\
MSSQL10_50.SS2008\MSSQL\DATA\AdventureWorksDW_Log.ldf'
問題 -我刷新我的服務器管理工作室，並沒有看到新的數據庫。爲什麼？我是否正確恢復了我的數據庫？如果不是，我該如何使用我在下面提供的代碼進行操作？如果您認爲代碼不好，是否有其他可靠的方法 來做到這一點？
PS - 它是一個恥辱，MS不會讓你輕鬆做到這一點。
附加信息 -
這裏是恢復多個數據庫的SP -
