如何在SQL Server 2008 Express的同一台服务器上克隆SQL Server数据库?

我有一个MS SQL Server 2008 Express系统，其中包含一个数据库，我想“复制和重命名”(用于测试目的)，但我不知道一个简单的方法来实现这一点。

我注意到在R2版本的SQL Server中有一个复制数据库向导，但遗憾的是我无法升级。

我们讨论的数据库大约是1g。我试图恢复我想复制到一个新数据库的数据库的备份，但没有运气。

您可以尝试分离数据库，在命令提示符下将文件复制到新的名称，然后附加两个db。

在SQL:

USE master;
GO 
EXEC sp_detach_db
    @dbname = N'OriginalDB';
GO

在命令提示符下(为了这个例子，我简化了文件路径):

copy c:\OriginalDB.mdf c:\NewDB.mdf
copy c:\OriginalDB.ldf c:\NewDB.ldf

还是用SQL:

USE master;
GO
CREATE DATABASE OriginalDB
    ON (FILENAME = 'C:\OriginalDB.mdf'),
       (FILENAME = 'C:\OriginalDB.ldf')
    FOR ATTACH;
GO
CREATE DATABASE NewDB
    ON (FILENAME = 'C:\NewDB.mdf'),
       (FILENAME = 'C:\NewDB.ldf')
    FOR ATTACH;
GO

其他回答

原来我试图从备份中错误地进行恢复。

最初我创建了一个新数据库，然后尝试在这里恢复备份。我本应该做的，也是最终有效的，是打开恢复对话框，并在目标字段中输入新数据库的名称。

因此，简而言之，从备份中恢复是有效的。

谢谢大家的反馈和建议

Install Microsoft SQL Management Studio, which you can download for free from Microsoft's website: Version 2008 Microsoft SQL Management Studio 2008 is part of SQL Server 2008 Express with Advanced Services Version 2012 Click download button and check ENU\x64\SQLManagementStudio_x64_ENU.exe Version 2014 Click download button and check MgmtStudio 64BIT\SQLManagementStudio_x64_ENU.exe Open Microsoft SQL Management Studio. Backup original database to .BAK file (db -> Task -> Backup). Create empty database with new name (clone). Note comments below as this is optional. Click to clone database and open restore dialog (see image) Select Device and add the backup file from step 3. Change destination to test database Change location of database files, it must be different from the original. You can type directly into text box, just add postfix. (NOTE: Order is important. Select checkbox, then change the filenames.) Check WITH REPLACE and WITH KEEP_REPLICATION
