Question

我在数据库服务器上有一堆.bak个文件，我创建了一个存储过程来执行它（目前在master中）。执行我的存储过程似乎正确地覆盖我的数据几乎，但它遗漏了.bak文件中包含的最新数据。

如果我手动恢复.bak，我拥有所有数据，当我的存储过程执行此操作时，我遗漏了一些数据。我有预感它的WITH REPLACE？没有它我会得到一些其他错误。

-- Insert statements for procedure here
ALTER DATABASE dbName SET SINGLE_USER WITH ROLLBACK IMMEDIATE

RESTORE Database dbName 
FROM DISK = N'C:\Backups\Databases\dbName.bak'
WITH REPLACE,
MOVE 'dbName' TO N'C:\Backups\Databases\DATA\dbName.mdf',  
MOVE 'dbName_log' TO N'C:\Backups\Databases\DATA\dbName.ldf',  
NOUNLOAD,  STATS = 5

ALTER DATABASE dbName 
    SET MULTI_USER WITH ROLLBACK IMMEDIATE

我对SQL Server不太满意，有人对如何解决我的问题有任何指导吗？

解决方案：设置FILE = n我没有指定它，默认情况下假设为1我相信，将其设置为4（最新备份）解决了我的问题

在您的查询中，您没有将任何文件组移动到特定文件夹loaction中尝试像这样

  USE [master]
    ALTER DATABASE [AdventureWorks2012] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
    RESTORE DATABASE [AdventureWorks2012_Temp] 
    FROM  DISK = N'D:\Backup\AdventureWorks2012.bak' 
    WITH  FILE = 1,  
    MOVE N'AdventureWorks2012_Data' TO N'D:\Backup\AdventureWorks\AdventureWorks2012_1.mdf',  
    MOVE N'AdventureWorks2012_Log' TO N'D:\Backup\AdventureWorks\AdventureWorks2012_1_Log.ldf',  
    NOUNLOAD,  STATS = 5
    GO
    ALTER DATABASE [AdventureWorks2012] SET MULTI_USER WITH ROLLBACK IMMEDIATE

试试这种方式

RESTORE DATABASE ReportServerSplitCopy FROM
 DISK = 'D:\DBBackups\ReportServer\ReportServer_Split1.bak'
,DISK = 'D:\DBBackups\ReportServer\ReportServer_Split2.bak'
,DISK = 'D:\DBBackups\ReportServer\ReportServer_Split3.bak'
WITH REPLACE ,
MOVE 'ReportServer' TO 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER11\MSSQL\DATA\ReportServerSplitCopy.mdf',
MOVE 'ReportServer_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER11\MSSQL\DATA\ReportServerSplitCopy_log.ldf'
GO
