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。

如果你是MS SQL 2014及更新版本;

DBCC CLONEDATABASE (CurrentDBName, NewDBName)
GO

使用MS SQL Server 2012，您需要执行3个基本步骤:

First, generate .sql file containing only the structure of the source DB right click on the source DB and then Tasks then Generate Scripts follow the wizard and save the .sql file locally Second, replace the source DB with the destination one in the .sql file Right click on the destination file, select New Query and Ctrl-H or (Edit - Find and replace - Quick replace) Finally, populate with data Right click on the destination DB, then select Tasks and Import Data Data source drop down set to ".net framework data provider for SQL server" + set the connection string text field under DATA ex: Data Source=Mehdi\SQLEXPRESS;Initial Catalog=db_test;User ID=sa;Password=sqlrpwrd15 do the same with the destination check the table you want to transfer or check box besides "source: ..." to check all of them

你完成了。

来自SSMS:

1 -备份原始数据库到。bak文件(your_source_db -> Task -> Backup)。

2 -右键点击“数据库”和“恢复数据库”

3 -设备>…(按钮)>添加>选择your_source_db.bak

4 -在“General”选项卡，在“Destination”部分，将“Database”your_source_db重命名为new_name_db

5 -在“文件”选项卡，勾选“重新定位所有文件到文件夹”，

在“还原为”列中重命名两个lignes，以保持与new_name_db(。mdf _log.ldf)

6 -在“选项”选项卡，“恢复选项”部分，勾选两个拳头选项(“覆盖…”'， '保存…')，对于'恢复状态':'恢复与恢复'

也要确保在“尾日志备份”部分的选项是不勾选的，以避免保持源db在“恢复状态”!

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
