右键单击要克隆的数据库，单击Tasks，单击Copy database ....遵循向导，您就完成了。

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。

解决方案，基于这条评论:https://stackoverflow.com/a/22409447/2399045。 只需设置:DB名称，临时文件夹，DB文件文件夹。 运行后，您将拥有名称为“sourceDBName_yyyy-mm-dd”格式的DB副本。

-- Settings --
-- New DB name will have name = sourceDB_yyyy-mm-dd
declare @sourceDbName nvarchar(50) = 'MyDbName';
declare @tmpFolder nvarchar(50) = 'C:\Temp\'
declare @sqlServerDbFolder nvarchar(100) = 'C:\Databases\'

--  Execution --
declare @sourceDbFile nvarchar(50);
declare @sourceDbFileLog nvarchar(50);
declare @destinationDbName nvarchar(50) = @sourceDbName + '_' + (select convert(varchar(10),getdate(), 121))
declare @backupPath nvarchar(400) = @tmpFolder + @destinationDbName + '.bak'
declare @destMdf nvarchar(100) = @sqlServerDbFolder + @destinationDbName + '.mdf'
declare @destLdf nvarchar(100) = @sqlServerDbFolder + @destinationDbName + '_log' + '.ldf'

SET @sourceDbFile = (SELECT top 1 files.name 
                    FROM sys.databases dbs 
                    INNER JOIN sys.master_files files 
                        ON dbs.database_id = files.database_id 
                    WHERE dbs.name = @sourceDbName
                        AND files.[type] = 0)

SET @sourceDbFileLog = (SELECT top 1 files.name 
                    FROM sys.databases dbs 
                    INNER JOIN sys.master_files files 
                        ON dbs.database_id = files.database_id 
                    WHERE dbs.name = @sourceDbName
                        AND files.[type] = 1)

BACKUP DATABASE @sourceDbName TO DISK = @backupPath

RESTORE DATABASE @destinationDbName FROM DISK = @backupPath
WITH REPLACE,
   MOVE @sourceDbFile     TO @destMdf,
   MOVE @sourceDbFileLog  TO @destLdf

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

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，

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。
