采取Backup/Restore的方式复制数据库

转自：http://blog.csdn.net/tianshijianbing1989/article/details/41013885

SQL Server 2008如何copy database：

方法一：使用Microsoft SQL Server Management Studio中的Copy Database Wizard来辅助完成。（很容易失败）

方法二：采取Backup/Restore的方式（推荐）

a.备份数据库到磁盘

[sql]
view plaincopy





BACKUP DATABASE Source_Database
TO DISK = 'D:\Backup\Source_Database.bak'
WITH FORMAT;

b.查看备份文件的逻辑文件

[sql]
view plaincopy





RESTORE FILELISTONLY
FROM DISK = 'D:\Backup\Source_Database.bak';

c.创建目标数据库

[sql]
view plaincopy





CREATE DATABASE Target_Database;

d.从磁盘复制数据库

[sql]
view plaincopy





/*
利用bak恢复数据库，强制还原(REPLACE)
STATS = 10 每完成10%显示一条记录
Source_Database和Source_Database_log是上面D:\Backup\Source_Database.bak里的逻辑文件
*/
RESTORE DATABASE Target_Database
FROM DISK='D:\Backup\Source_Database.bak'
WITH
MOVE 'Source_Database' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Target_Database.mdf',
MOVE 'Source_Database_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Target_Database_log.ldf',
STATS = 10,REPLACE

附：实例：

USE [database_name]

GO

/****** Object: StoredProcedure [dbo].[CopyDatabase] ******/

SET ANSI_NULLS OFF

GO

SET QUOTED_IDENTIFIER OFF

GO

/****** 对象: 存储过程 dbo.CopyDatabase ******/

/****** 对象: 存储过程 dbo.CopyDatabase ******/

CREATE PROCEDURE [dbo].[CopyDatabase]

(@SourceDbName varchar(50),

@NewDbName varchar(50))

AS

declare @tempDevice varchar(50)

declare @tempBkupFile varchar(50)

declare @tempBkPath varchar(200)

declare @dataFilePath varchar(200)

declare @logFilePath varchar(200)

declare @sdataFile varchar(100)

declare @slogFile varchar(100)

SET @sdataFile=@SourceDbName+"_data" /*查看备份文件的逻辑文件RESTORE FILELISTONLY FROM DISK =tempBkPath+tempBkupFile';
特别重要，此处就按查看结果设置，下面slogFile相同的道理*/

SET @slogFile=@SourceDbName+"_log"

SET @dataFilePath="D:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\data\"+@NewDbName+".mdf"

SET @logFilePath="D:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\data\"+@NewDbName+".ldf"

SET @tempBkupFile=@NewDbName+".dat"

SET @tempBkPath="D:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\BACKUP\"+@tempBkupFile

SET @tempDevice=@NewDbName+"back"

EXEC sp_addumpdevice "disk", @tempDevice,@tempBkPath

BACKUP DATABASE @SourceDbName to @tempDevice

RESTORE DATABASE @NewDbName FROM @tempDevice WITH RECOVERY,

MOVE @sdataFile TO @dataFilePath,

MOVE @slogFile TO @logFilePath

EXEC sp_dropdevice @tempDevice,"DELFILE"

GO
