在SQL Server 2012 Express中創建數據庫副本

Question

您好，我有用戶在使用的數據庫。 我想創建該數據庫的副本以進行測試。

誰能告訴我該怎么做？ 我試過一切，從SQL Server Express中復制數據庫？

但是復制文件並附加它會破壞第一個數據庫，並嘗試將備份還原到新數據庫中，從而引發錯誤，指出數據庫不一樣。

誰能建議我解決方案？

正如@Nadeem_MK所建議的，我創建了備份，現在我正嘗試使用以下腳本進行還原：

RESTORE DATABASE [Equipment Test]  -- use your new db name
FROM  DISK = N'C:\Backup\ExistingDb.bak'  --Path of backup location
WITH  REPLACE,RECOVERY,  
MOVE N'Equipment Test' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\ExistingDb.mdf',  --logical name and physical name 
MOVE N'Equipment Test_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\ExistingDb.ldf' --logical name and physical name

這會引發錯誤：

Msg 1834, Level 16, State 1, Line 1
The file 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment.mdf' cannot be overwritten.  It is being used by database 'Equipment'.
Msg 3156, Level 16, State 4, Line 1
File 'Equipment' cannot be restored to 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment.mdf'. Use WITH MOVE to identify a valid location for the file.
Msg 1834, Level 16, State 1, Line 1

The file 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment_log.ldf' cannot be overwritten.  It is being used by database 'Equipment'.
Msg 3156, Level 16, State 4, Line 1
File 'Equipment_log' cannot be restored to 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment_log.ldf'. Use WITH MOVE to identify a valid location for the file.
Msg 3119, Level 16, State 1, Line 1
Problems were identified while planning for the RESTORE statement. Previous messages provide details.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

如您所見，還原正在嘗試更改備份數據庫（而非新數據庫）中的文件

@Update：備份腳本：

--To backup Database (Delete the previous backup first)
BACKUP DATABASE Equipment --Database Name
TO DISK = 'C:\Backup\Equipment.bak' WITH INIT --Path of backup location

文件位置：

C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment.mdf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment_log.ldf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment Test.mdf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment Test_log.mdf

恢復功能：

RESTORE DATABASE [Equipment Test]  -- use your new db name
FROM  DISK = N'C:\Backup\Equipment.bak'  --Path of backup location
WITH  REPLACE,RECOVERY,  
MOVE N'Equipment Test' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment2.mdf',  --logical name and physical name 
MOVE N'Equipment Test_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment_log2.ldf' --logical name and physical name

Answer 1

您可以使用以下腳本創建備份並還原它；

--To backup Database (Delete the previous backup first)
BACKUP DATABASE ExistingDb --Database Name
TO DISK = 'C:\DBBackup\ExistingDb.bak' WITH INIT --Path of backup location

然后恢復它；

RESTORE DATABASE NewDbName  -- use your new db name
FROM  DISK = N'C:\DBBackup\ExistingDb.bak'  --Path of backup location
WITH  REPLACE,RECOVERY,  
MOVE N'Reporting' TO N'C:\Databases\MDF\NewDbName.mdf',  --logical name and physical name 
MOVE N'Reporting_log' TO N'C:\Databases\LDF\NewDbName.ldf' --logical name and physical name

Answer 2

假設這是原始數據庫的路徑：

C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment.mdf
C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment_log.ldf

備份的文件名稱為

Equipment.bak

確保新數據庫的文件名與舊數據庫的文件名不同。 那就是你得到的錯誤的意思：

The file 'C:\...' cannot be overwritten.  It is being used by database 'Equipment'.

說明：不要使用已有文件的文件名！

而是給這些起一個新的名字。 像這樣：

RESTORE DATABASE [Equipment Test]  -- use your new db name
FROM  DISK = N'C:\Backup\Equipment.bak'  --Path of backup location
WITH  REPLACE,RECOVERY,  
MOVE N'Equipment Test' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment2.mdf',  --logical name and physical name 
MOVE N'Equipment Test_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Equipment_log2.ldf' --logical name and physical name

這基本上是Nadeem_MK的答案，但是現在您應該有了Equipment2.mdf和Equipment_log.ldf ，而不是原來的名稱Equipment.mdf和Equipment_log.ldf 。

如果這可行，也請反對Nadeem_MK的回答，因為這基本上是他在說的。 我只是沒有足夠的聲譽來評論他的答案。

Answer 3

簡單，請執行以下步驟：

1. 備份主數據庫。

2. 創建新數據庫，並使用您想要提供的名稱進行測試。

3. 將主數據庫的備份還原到新創建的測試數據庫。

完成！

Answer 4

注意：下面的功能在SQL Express中不可用。為了完整起見，我在這里留下了答案，僅供以后的讀者參考。

我能想到的最簡單的方法是讓Management Studio完成所有工作！

右鍵單擊要復制的數據庫，然后在“ 任務”菜單下查找“ 復制數據庫...”選項。

Answer 5

為什么不編寫數據庫腳本並運行腳本？
