Sql server Microsoft SQL Server，使用一个命令还原数据库备份

当我们从生产环境中复制数据库时，我们对数据库进行备份、压缩并复制备份。然后，我们必须使用SQLServerGUI进行恢复，这涉及到在多个菜单和窗口中导航。据我所知，SQL Server的内置存储过程无法做到这一点，因为您可能不知道数据库的

逻辑文件名

（还原时需要该文件名）。因此，通过查询执行此操作包括以下内容：

RESTORE FILELISTONLY
FROM DISK = 'C:\backup_of_production_database.bak'
GO

上面提供了备份文件中的逻辑文件名，然后您必须在下一个查询中使用这些逻辑名称

RESTORE DATABASE NewDevelopmentDatabase
FROM DISK = 'C:\backup_of_production_database.bak'
WITH MOVE 'YourMDFLogicalName' TO 'C:\mssql\data\DataYourMDFFile.mdf',
MOVE 'YourLDFLogicalName' TO 'C:\mssql\data\DataYourLDFFile.mdf'

如您所见，这似乎效率低下，因为您必须在下一个查询中手动输入逻辑文件名

您可以在下面找到我对这个问题的解决方案。

解决方案： 使用各种资源，我提出了以下存储过程，可以将此恢复简化为一个步骤。我希望它能像对我一样对别人有用

我确信关于这个查询的一些事情可以改进，但是我已经浪费了足够的时间来尝试这个解决方案。不管怎样，我很想听到一些反馈。我希望其他人会觉得这很有用

下面是一个SQL脚本，它将在不需要交互的情况下恢复数据库。 只需输入您的“源数据库”和“目标数据库”-脚本将完成其余工作：）

请把这个分成问题和答案。否则谢谢！如果LogicalName与PhysicalName不同，这将不起作用。如果有多个数据库具有相同的“名称”但不同的“物理名称”，这也会有问题。SELECTFROM“master.sys.master_文件”中的where子句需要更具体。除此之外，还有一个非常有用的脚本。
