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。

为执行xp_cmdshel配置sql server

EXEC sp_configure 'show advanced options', 1
GO
RECONFIGURE
GO
EXEC sp_configure 'xp_cmdshell', 1
GO
RECONFIGURE
GO

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

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。

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

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。

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

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，
