Question

在SQL server 2008R2中，我尝试使用此处给出的SQL查询还原位于一个文件夹中的多个数据库/ BAK文件 - http://www.karaszi.com/sqlserver/code/sp_RestoreFromAllFilesInDirectory_2008sp1.txt

它使用这样的存储过程，其代码在最后给出 -

exec sp_RestoreFromAllFilesInDirectory 'C:\Mybakfiles\', 
'D:\Mydatabasesdirectory\' , 
'C:\MylogDirectory\'

感兴趣的文件夹 - ＆＃39; C：\ Mybakfiles \＆＃39;，＆＃39; D：\ Mydatabasesdirectory \＆＃39; ，＆＃39; C：\ MylogDirectory \＆＃39;

您应该知道第一个文件夹的路径。可以找到第二个和第三个查询或SSMS。有关查询，请参阅alex aza的答案 - What is the most efficient way to restore multiple databases in SQL 2008。我最后还提出了他的问题。

我将所有BAK文件复制到 - C：\ Program Files \ Microsoft SQL Server \ MSSQL10_50.SS2008 \ MSSQL \ Backup \

然后，我按照以下步骤执行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\'

并获得以下示例输出 -

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'

问题 - 我在管理工作室刷新了我的服务器，没有看到新的数据库。为什么？我是否正确恢复了数据库？如果没有，我该如何使用下面提供的代码呢？如果你认为代码不好，还有其他可靠的方法做到了吗？

PS - 很遗憾MS不会让你轻易做到这一点。

Answer 1

首先感谢您提供sp_RestoreFromAllFilesInDirectory脚本作为创作者主页不再可用。

您提供的脚本只打印生成的sql，因此只需要取消注释该行：

EXEC(@sql)

我知道这个问题太旧了，但是我拯救了别人

Answer 2

非常感谢您这个非常有用的脚本。

我为SQL Server的较新版本添加了新列，并在还原之前将alter数据库添加到了单用户模式，并在还原之后将其更改回了多用户。默认情况下，这些选项被注释掉。

--If you need to overwrite the existing database uncomment this 
--SET @sql = 'ALTER DATABASE [' + @DbName + '] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
--RESTORE DATABASE ' + @DbName + ' FROM DISK = ''' + 
--@dirfile + ''' WITH  FILE = 1, MOVE ' 

--If you need to overwrite the existing database uncomment this as it will reinstate the database to multi-user
--SET @sql = @sql + '''' + @LogicalName + ''' TO ''' + 
--@DestDirLogFiles + @LogicalName  + '.ldf '', NOUNLOAD,  REPLACE,  STATS = 5
--ALTER DATABASE [' + @DbName + '] SET MULTI_USER

Answer 3

要使脚本在MS SQL Server 2012上运行，请将另一列添加到#bdev表：

Containment int

另外，我必须将#dbfiles表中的几列更改为bigint。

Answer 4

脚本的第一个thanx :) 请检查列RESTOREHEADERONLY和FILELISTONLY。您需要添加一些列。至少我的工作添加了新的列。
