该程序以不同的名称将数据库复制到同一服务器。我依赖于这个网站上给出的例子，并进行了一些改进。

如果数据库不是很大，你可以看看SQL Server Management Studio Express中的“Script database”命令，它位于资源管理器中数据库项本身的上下文菜单中。

你可以选择什么都脚本;当然，您需要对象和数据。然后将整个脚本保存到一个文件中。然后，您可以使用该文件重新创建数据库;只要确保顶部的USE命令被设置为正确的数据库。

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。

在SQL Server 2008 R2操作系统中，将数据库以文件的形式备份到文件夹中。 然后选择“Database”文件夹中的恢复选项。 在向导中输入目标数据库中需要的新名称。 然后选择“从文件恢复”并使用刚才创建的文件。 我就这样做了，它非常快(我的DB很小，但仍然) 巴勃罗。

这里提到的解决方案都不适合我-我使用的是SQL Server Management Studio 2014。

相反，我不得不取消“选项”屏幕中的“在恢复前进行尾日志备份”复选框:在我的版本中，默认情况下它是选中的，并阻止恢复操作完成。 取消检查后，还原操作继续进行，没有出现问题。

另一种方法是使用导入/导出向导，首先创建一个空数据库，然后选择具有源数据库的源服务器，然后在目标中选择具有目标数据库的同一服务器(使用您首先创建的空数据库)，然后点击完成

它会创建所有的表，并将所有的数据传输到新的数据库中，
