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

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

您可以只创建一个新数据库，然后转到任务，导入数据，并将所有数据从您想要复制的数据库导入到刚刚创建的数据库。

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。

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。
