Question

我制作了一个脚本来恢复.bak或备份文件。它适用于某些数据库，但不适用于某些数据库。如何使其适用于任何类型的.bak文件？这是在sql server 2008中。错误消息是 -

Msg 3234, Level 16, State 1, Line 1
Logical file 'Northwind_Data' is not part of database 'Northwind'. 
Use RESTORE FILELISTONLY to list the logical file names.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

脚本 -

IF DB_ID('Northwind') IS NULL
BEGIN
RESTORE DATABASE [Northwind]
FILE = N'Northwind_Data'
FROM 
DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\Northwind.bak'
WITH  FILE = 1,
MOVE N'Northwind_Data'
TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\DATA\Northwind.mdf',
MOVE N'Northwind_Log'
 TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\DATA\Northwind_0.LDF',
NOUNLOAD,  STATS = 10
END

Answer 1

请在sql下面运行并检查逻辑名称

RESTORE FILELISTONLY 
FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\Northwind.bak'

然后在下面的脚本中替换RESTORE FILELISTONLY显示的逻辑名称

--If database already exists do not restore
IF DB_ID('Northwind') IS NULL 
BEGIN
  RESTORE DATABASE [Northwind]
  FILE = N'Northwind_Data'
  FROM DISK = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\Backup\Northwind.bak'
  WITH 
    FILE = 1, NOUNLOAD, STATS = 10,
    MOVE N'YOUR logical name of data file as shown by RESTORE FILELISTONLY command'
    TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\DATA\Northwind.mdf',
    MOVE N'YOUR logical name of Log file as shown by RESTORE FILELISTONLY command'
    TO N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.SS2008\MSSQL\DATA\Northwind_0.LDF'
END

当我尝试在MS SQL Server 2012上还原数据库时遇到了这个问题。

这是我用于还原数据库的脚本：

USE master;
GO

ALTER DATABASE my_db SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO

    
RESTORE DATABASE my_db
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_backup.bak'
    WITH REPLACE,
    MOVE 'my_db' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\my_db.mdf',
    MOVE 'my_db_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\my_db_log.ldf'
GO
    
ALTER DATABASE my_db SET MULTI_USER;
GO

我遇到了错误：

Msg 3234, Level 16, State 1, Line 1
Logical file 'my_db' is not part of database 'my_db'. 
Use RESTORE FILELISTONLY to list the logical file names.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

这是我修复的方式：

问题是我没有正确引用逻辑文件。

我必须在备份文件上运行以下RESTORE FILELISTONLY命令：

RESTORE FILELISTONLY 
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_backup.bak'

这分别显示了数据库的数据和日志文件的 LogicalName 和相应的 PhysicalName ：

LogicalName      PhysicalName               
com.my_db        C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db.mdf
com.my_db_log    C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db_log.ldf

我要做的就是简单地在脚本中分别替换数据库的数据和日志文件的 LogicalName 和相应的 PhysicalName ：

USE master;
GO

ALTER DATABASE my_db SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO

    
RESTORE DATABASE my_db
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_backup.bak'
    WITH REPLACE,
    MOVE 'com.my_db' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db.mdf',
    MOVE 'com.my_db_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db_log.ldf'
GO
    
ALTER DATABASE my_db SET MULTI_USER;
GO

数据库还原任务成功运行：

这篇文章帮助我弄清楚了SQL Error – Logical file ‘XYZ_Log2’ is not part of database ‘XYZ’. Use RESTORE FILELISTONLY to list the logical file names.

仅此而已。

我希望这会有所帮助

检查数据库属性并确保逻辑名称与文件名相同。使用Alter Database命令修改它们：

ALTER DATABASE [Northwind] MODIFY FILE (NAME=N'Northwind_Data', NEWNAME=N'Northwind')
GO
ALTER DATABASE [Northwind] MODIFY FILE (NAME=N'Northwind_Data_log', NEWNAME=N'Northwind_log')
GO

Answer 4

我正在使用Powershell来执行此操作，并且遇到相同的错误。我得到的是我正在使用 “ $ db_log.mdf”和下划线是变量定义的有效字符，因此它实际上是在寻找$ db_log而不进行串联。

所以我的代码如下：

  $db = "MyNewDb"
  $restoreSuffix = "_V1"
  $newDbName = $db
  $dataFileOrigin = $db
  $logFileOrigin = $db+"_log"
  $dataFileLocation = "$dataAndLogFileDestination\$db$restoreSuffix.mdf"
  $logFileLocation = "$dataAndLogFileDestination\$db$restoreSuffix"+"_log.ldf"

  echo "Renaming and Relocating files to ($newDbName)"

  $RelocateData = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile("$dataFileOrigin", "$dataFileLocation")
  $RelocateLog = New-Object Microsoft.SqlServer.Management.Smo.RelocateFile("$logFileOrigin", "$logFileLocation")
  Restore-SqlDatabase -ServerInstance "." -Database "$newDbName" -BackupFile "$backupLocation$db.bak" -RelocateFile @($RelocateData,$RelocateLog)

Answer 5

我正在尝试从UNC路径上的备份还原数据库。有两个问题：

数据库以数字123DbName开头，因此必须用[]包裹，例如[123DbName]
我正在编写要移动的服务器的完整UNC路径：\\ server \ e $ \ data | \\ server \ f $ \ log，一旦我删除了服务器部分并仅保留e和f一切正常。

Answer 6

你所要求的并不是微不足道的，并且有几个潜在的缺陷（如果它存在，你想覆盖数据库吗？，当你试图覆盖时数据库正在使用怎么办？你想要把它物理文件一直在同一目录中？等等。）..

幸运的是之前有人问过，look here，我没有测试过，但它看起来很合理。

错误 - 逻辑文件不是数据库的一部分。使用RESTORE FILELISTONLY列出逻辑文件名
