--以下为修改过程

--step

1

:

修改数据库名称

USE

master

GO

ALTER

DATABASE

DB_BEIJING

SET

SINGLE_USER

WITH

ROLLBACK

IMMEDIATE

GO

EXEC

master..sp_renamedb

'DB_BEIJING','DB_SHANGHAI'

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'DB_SHANGHAI')

GO

/*

ROWS

ONLINE

DB_BEIJING_log

W:\Log\DB_BEIJING_log.ldf

LOG

ONLINE

*/

--step

3

:

修改数据库逻辑文件名称

USE

master

GO

ALTER

DATABASE

DB_SHANGHAI

SET

SINGLE_USER

WITH

ROLLBACK

IMMEDIATE

GO

ALTER

DATABASE

DB_SHANGHAI

MODIFY

FILE

(NAME=N'DB_BEIJING',

NEWNAME=N'DB_SHANGHAI')

GO

ALTER

DATABASE

DB_SHANGHAI

MODIFY

FILE

(NAME=N'DB_BEIJING_log',

NEWNAME=N'DB_SHANGHAI_log')

GO

ALTER

DATABASE

DB_SHANGHAI

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

DB_SHANGHAI

SET

OFFLINE

WITH

ROLLBACK

IMMEDIATE

GO

EXEC

xp_cmdshell

'RENAME

"X:\DATA\DB_BEIJING.mdf",

"DB_SHANGHAI.mdf"'

GO

EXEC

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]

GO

ALTER

DATABASE

DB_SHANGHAI

MODIFY

FILE

(NAME

=DB_SHANGHAI,

FILENAME

=

'X:\DATA\DB_SHANGHAI.mdf')

GO

ALTER

DATABASE

DB_SHANGHAI

MODIFY

FILE

(NAME

=DB_SHANGHAI_log,

FILENAME

=

'W:\LOG\DB_SHANGHAI_log.ldf')

GO

ALTER

DATABASE

DB_SHANGHAI

SET

ONLINE

--step

7

:

查看全部修改完成后的数据库情况

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'DB_SHANGHAI')

GO

/*

File

Type

State

X:\DATA\DB_SHANGHAI.mdf

ROWS

ONLINE

DB_SHANGHAI_log

W:\LOG\DB_SHANGHAI_log.ldf

LOG

ONLINE

*/

--step

8

:

关闭xp_cmdshell支持

USE

master

GO

sp_configure

'xp_cmdshell',

0

GO

RECONFIGURE

WITH

OVERRIDE

GO

sp_configure

'show

advanced

options',0

GO

RECONFIGURE

WITH

OVERRIDE

GO

1、首先需要从开始菜单中找到【SQL Server 配置管理器】。

2、然后会看到【SQL Server（MSSQLSERVER）】正处于运行的状态。

3、右击它然后【重新启动】任务进程。

4、然后打开sql2012选择一个数据库右击【重命名】。

5、然后输入【新的数据库名称】就重命名完毕了。

其实在修改数据库名称之前，如果有用户连接到数据库的话会造成数据库重命名失败，可以先执行

select

spid

from

master.dbo.sysprocesses

where

dbid=db_id('OldDbName')

结果集中显示的是当前连接到数据库OldDbName的连接

比如结果是

79

81

当然，实际值应该不是这两个

然后执行

kill

79

kill

81

关闭已建立的连接，之后再执行

EXEC

sp_dboption

'OldDbName',

'Single

User',

'TRUE'

EXEC

sp_renamedb

'OldDbName',

'NewDbName'

EXEC

sp_dboption

'NewDbName',

'Single

User',

'FALSE'

上述语句最好都在master数据库中执行。

另外也可以这样：

先分离数据库，然后附加的时候再修改就可以了

SQL

Server不支持直接修改数据库名称
