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。

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

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。

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。

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。

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,

这是我使用的脚本。有点棘手,但很有效。在SQL Server 2012上测试。

DECLARE @backupPath nvarchar(400);
DECLARE @sourceDb nvarchar(50);
DECLARE @sourceDb_log nvarchar(50);
DECLARE @destDb nvarchar(50);
DECLARE @destMdf nvarchar(100);
DECLARE @destLdf nvarchar(100);
DECLARE @sqlServerDbFolder nvarchar(100);

SET @sourceDb = 'db1'
SET @sourceDb_log = @sourceDb + '_log'
SET @backupPath = 'E:\DB SQL\MSSQL11.MSSQLSERVER\MSSQL\Backup\' + @sourceDb + '.bak'    --ATTENTION: file must already exist and SQL Server must have access to it
SET @sqlServerDbFolder = 'E:\DB SQL\MSSQL11.MSSQLSERVER\MSSQL\DATA\'
SET @destDb = 'db2'
SET @destMdf = @sqlServerDbFolder + @destDb + '.mdf'
SET @destLdf = @sqlServerDbFolder + @destDb + '_log' + '.ldf'

BACKUP DATABASE @sourceDb TO DISK = @backupPath

RESTORE DATABASE @destDb FROM DISK = @backupPath
WITH REPLACE,
   MOVE @sourceDb     TO @destMdf,
   MOVE @sourceDb_log TO @destLdf
