sql server:alter database name的问题

--step 1 : 修改数据库名称

USE master

GO

ALTER DATABASE GeovinDuCms SET SINGLE_USER WITH ROLLBACK IMMEDIATE

GO

EXEC master..sp_renamedb 'GeovinDuCms','DuCms'

GO

ALTER DATABASE DB_SHANGHAI SET MULTI_USER

GO

--step 2 : 查看修改名称后的数据库逻辑名及物理文件名

USE master

GO

SELECT name AS [Logical Name], physical_name AS [DB File Path],type_desc AS [File Type],

state_desc AS [State] FROM sys.master_files

WHERE database_id = DB_ID(N'DuCms')

GO

--step 3 : 修改数据库逻辑文件名称

USE master

GO

ALTER DATABASE DuCms SET SINGLE_USER WITH ROLLBACK IMMEDIATE

GO

ALTER DATABASE DuCms MODIFY FILE (NAME=N'GeovinDuCms', NEWNAME=N'DuCms')

GO

ALTER DATABASE DuCms MODIFY FILE (NAME=N'GeovinDuCms_log', NEWNAME=N'DuCms_log')

GO

ALTER DATABASE DuCms SET MULTI_USER

GO

--step 4 : 修改数据库物理文件名称之前先打开xp_cmdshell支持

USE master

GO

sp_configure 'show advanced options',1

GO

RECONFIGURE WITH OVERRIDE

GO

sp_configure 'xp_cmdshell', 1

GO

RECONFIGURE WITH OVERRIDE

GO

--step 5 : 重命名数据库物理文件名称

USE [master]

GO

ALTER DATABASE DuCMS SET OFFLINE WITH ROLLBACK IMMEDIATE

EXEC xp_cmdshell 'RENAME "E:\2005database\GeovinDuCms.mdf", "DuCms.mdf"'

GO

EXEC xp_cmdshell 'RENAME "E:\2005database\GeovinDuCms_log.ldf", "DuCms_log.ldf"'

GO

--step 6 : 将数据库逻辑名称指向新的物理文件，并将数据库online

USE [master]

GO

ALTER DATABASE DuCMS MODIFY FILE (NAME =DuCms, FILENAME = 'E:\2005database\DuCms.mdf')

GO

ALTER DATABASE DuCMS MODIFY FILE (NAME =DuCms_log, FILENAME = 'E:\2005database\DuCms_log.ldf')

GO

ALTER DATABASE DuCMS SET ONLINE

GO

SELECT name AS [Logical Name], physical_name AS [DB File Path],type_desc AS [File Type],

state_desc AS [State] FROM sys.master_files

WHERE database_id = DB_ID(N'DuCMS')
