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。

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
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
脚本基于乔回答(分离，复制文件，附加两者)。
以Administrator帐户运行management Studio。
这是不必要的，但可能在执行时访问被拒绝错误。

运行脚本，但在@dbName和@copyDBName变量之前输入你的db名称。
USE master;
GO
DECLARE @dbName NVARCHAR(255) = 'Products'
DECLARE @copyDBName NVARCHAR(255) = 'Products_branch'
-- get DB files
CREATE TABLE ##DBFileNames([FileName] NVARCHAR(255))
EXEC('
INSERT INTO ##DBFileNames([FileName])
SELECT [filename] FROM ' + @dbName + '.sys.sysfiles')
-- drop connections
EXEC('ALTER DATABASE ' + @dbName + ' SET OFFLINE WITH ROLLBACK IMMEDIATE')
EXEC('ALTER DATABASE ' + @dbName + ' SET SINGLE_USER')
-- detach
EXEC('EXEC sp_detach_db @dbname = ''' + @dbName + '''')
-- copy files
DECLARE @filename NVARCHAR(255), @path NVARCHAR(255), @ext NVARCHAR(255), @copyFileName NVARCHAR(255), @command NVARCHAR(MAX) = ''
DECLARE
@oldAttachCommand NVARCHAR(MAX) =
'CREATE DATABASE ' + @dbName + ' ON ',
@newAttachCommand NVARCHAR(MAX) =
'CREATE DATABASE ' + @copyDBName + ' ON '
DECLARE curs CURSOR FOR
SELECT [filename] FROM ##DBFileNames
OPEN curs
FETCH NEXT FROM curs INTO @filename
WHILE @@FETCH_STATUS = 0
BEGIN
SET @path = REVERSE(RIGHT(REVERSE(@filename),(LEN(@filename)-CHARINDEX('\', REVERSE(@filename),1))+1))
SET @ext = RIGHT(@filename,4)
SET @copyFileName = @path + @copyDBName + @ext
SET @command = 'EXEC master..xp_cmdshell ''COPY "' + @filename + '" "' + @copyFileName + '"'''
PRINT @command
EXEC(@command);
SET @oldAttachCommand = @oldAttachCommand + '(FILENAME = "' + @filename + '"),'
SET @newAttachCommand = @newAttachCommand + '(FILENAME = "' + @copyFileName + '"),'
FETCH NEXT FROM curs INTO @filename
END
CLOSE curs
DEALLOCATE curs
-- attach
SET @oldAttachCommand = LEFT(@oldAttachCommand, LEN(@oldAttachCommand) - 1) + ' FOR ATTACH'
SET @newAttachCommand = LEFT(@newAttachCommand, LEN(@newAttachCommand) - 1) + ' FOR ATTACH'
-- attach old db
PRINT @oldAttachCommand
EXEC(@oldAttachCommand)
-- attach copy db
PRINT @newAttachCommand
EXEC(@newAttachCommand)
DROP TABLE ##DBFileNames
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。
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。
