需要帮助从一个文件夹中恢复多个数据库/bak 文件答案

【问题标题】：Need help to restore multiple databases/bak files from one folder需要帮助从一个文件夹中恢复多个数据库/bak 文件
【发布时间】：2014-03-05 19:38:09
【问题描述】：

在 SQL Server 2008R2 中，我尝试使用此处给出的 SQL 查询来恢复仅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，代码在最后给出 -

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

涉及的文件夹 - 'C:\Mybakfiles\'、'D:\Mydatabasesdirectory\'、'C:\MylogDirectory\'

您应该知道第一个文件夹的路径。第二个和第三个都可以找到通过查询或 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。我在最后也给出了他的问题。

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

然后，我进入执行SP如下-

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\'

并得到以下示例输出 -

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 Management Studio 中刷新了我的服务器，但没有看到新的数据库。为什么？我是否正确恢复了我的数据库？如果没有，我该如何使用我在下面提供的代码来做到这一点？如果你认为代码不好，有没有其他可靠的方法这样做？

PS - 可惜 MS 没有让你轻易做到这一点。

【解决方案1】：

首先感谢您提供sp_RestoreFromAllFilesInDirectory的脚本，因为创作者主页不再可用。

您提供的脚本仅打印生成的 sql，因此您只需取消注释该行：

EXEC(@sql)

我知道这个问题太老了，但我救了别人

【讨论】：

【解决方案2】：

非常感谢您提供这个非常有用的脚本。

我已为较新版本的 SQL Server 添加了新列，并在还原之前将更改数据库添加到单用户模式，并在还原后将其更改回多用户模式。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 = ''' +

--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

【解决方案3】：

要使脚本在 MS SQL Server 2012 上运行，请在 #bdev 表中添加另一列：

Containment int

另外，我必须将#dbfiles 表中的几列更改为 bigint。

【讨论】：

【解决方案4】：

首先感谢脚本:) 请检查RESTOREHEADERONLY 和FILELISTONLY 列。您需要添加一些列。添加新列时，至少我的工作正常。
