--step 1 : 修改数据库名称USE masterGOALTER DATABASE DB_BEIJING SET SINGLE_USER WITH ROLLBACK IMMEDIATEGOEXEC master..sp_renamedb 'DB_BEIJING','DB_SHANGHAI'GOALTER DATABASE DB_SHANGHAI SET MULTI_USERGO
--step 2 : 查看修改名称后的数据库逻辑名及物理文件名USE masterGOSELECT name AS [Logical Name], physical_name AS [DB File Path],type_desc AS [File Type],

--step 3 : 修改数据库逻辑文件名称USE masterGOALTER DATABASE DB_SHANGHAI SET SINGLE_USER WITH ROLLBACK IMMEDIATEGOALTER DATABASE DB_SHANGHAI MODIFY FILE (NAME=N'DB_BEIJING', NEWNAME=N'DB_SHANGHAI')GOALTER DATABASE DB_SHANGHAI MODIFY FILE (NAME=N'DB_BEIJING_log', NEWNAME=N'DB_SHANGHAI_log')GOALTER DATABASE DB_SHANGHAI SET MULTI_USERGO
--step 4 : 修改数据库物理文件名称之前先打开xp_cmdshell支持USE masterGOsp_configure 'show advanced options',1GORECONFIGURE WITH OVERRIDEGOsp_configure 'xp_cmdshell', 1GORECONFIGURE WITH OVERRIDEGO
--step 5 : 重命名数据库物理文件名称
USE [master]GOALTER DATABASE DB_SHANGHAI SET OFFLINE WITH ROLLBACK IMMEDIATEGOEXEC xp_cmdshell 'RENAME X:\DATA\DB_BEIJING.mdf, DB_SHANGHAI.mdf'GOEXEC xp_cmdshell 'RENAME W:\Log\DB_BEIJING_log.ldf, DB_SHANGHAI_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]GOALTER DATABASE DB_SHANGHAI MODIFY FILE (NAME =DB_SHANGHAI, FILENAME = 'X:\DATA\DB_SHANGHAI.mdf')GOALTER DATABASE DB_SHANGHAI MODIFY FILE (NAME =DB_SHANGHAI_log, FILENAME = 'W:\LOG\DB_SHANGHAI_log.ldf')GOALTER DATABASE DB_SHANGHAI SET ONLINE
--step 7 : 查看全部修改完成后的数据库情况USE masterGOSELECT name AS [Logical Name], physical_name AS [DB File Path],type_desc AS [File Type],
