修改SQL Server 2005/2008 用户数据库文件默认路径和默认备份路

本内容适用于SQL Server 2005 Standard Version 64-bit 和 SQL Server 2008 Standard Version 64-bit 双实例同时安装在一个 Windows Server 2008 Standard Version 64-bit OS的环境。
以下仅为参照,如果有多个数据库实例,可能会有些许不同:

2005的情况:
 

复制代码代码如下:

Windows Server 2005 Standard Version 64-bit
SQL Server 2005 Standard Version 64-bit

--查询用户库Data文件默认路径:
DECLARE @DefaultData VARCHAR(100)
EXEC master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer',
@value_name='DefaultData',
@DefaultData=@DefaultData OUTPUT
SELECT @DefaultData

--查询用户库Log文件默认路径:
DECLARE @DefaultLog VARCHAR(100)
EXEC master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer',
@value_name='DefaultLog',
@DefaultLog=@DefaultLog OUTPUT
SELECT @DefaultLog

--查询用户库备份文件默认路径:
DECLARE @BackupDirectory VARCHAR(100)
EXEC master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer',
@value_name='BackupDirectory',
@BackupDirectory=@BackupDirectory OUTPUT
SELECT @BackupDirectory

--修改用户库Data文件默认路径:
EXEC master..xp_regwrite
@rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer',
@value_name='DefaultData',
@type='REG_SZ',
@value='D:\SQL2005\Data'

--修改用户库Log文件默认路径:
EXEC master..xp_regwrite
@rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer',
@value_name='DefaultLog',
@type='REG_SZ',
@value='D:\SQL2005\Log'

--修改用户库备份文件默认路径:
EXEC master..xp_regwrite
@rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL.1\MSSQLServer',
@value_name='BackupDirectory',
@type='REG_SZ',
@value='D:\SQL2005\DBBak'

 

2008的情况:
 

复制代码代码如下:

Windows Server 2008 Standard Version 64-bit
SQL Server 2008 Standard Version 64-bit

--查询用户库Data文件默认路径:
DECLARE @DefaultData VARCHAR(100)
EXEC master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL10.SQL2008\MSSQLServer',
@value_name='DefaultData',
@DefaultData=@DefaultData OUTPUT
SELECT @DefaultData

--查询用户库Log文件默认路径:
DECLARE @DefaultLog VARCHAR(100)
EXEC master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL10.SQL2008\MSSQLServer',
@value_name='DefaultLog',
@DefaultLog=@DefaultLog OUTPUT
SELECT @DefaultLog

--查询用户库备份文件默认路径:
DECLARE @BackupDirectory VARCHAR(100)
EXEC master..xp_regread @rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL10.SQL2008\MSSQLServer',
@value_name='BackupDirectory',
@BackupDirectory=@BackupDirectory OUTPUT
SELECT @BackupDirectory

--修改用户库Data文件默认路径:
EXEC master..xp_regwrite
@rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL10.SQL2008\MSSQLServer',
@value_name='DefaultData',
@type='REG_SZ',
@value='D:\SQL2008\Data'

--修改用户库Log文件默认路径:
EXEC master..xp_regwrite
@rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL10.SQL2008\MSSQLServer',
@value_name='DefaultLog',
@type='REG_SZ',
@value='D:\SQL2008\Log'

--修改用户库备份文件默认路径:
EXEC master..xp_regwrite
@rootkey='HKEY_LOCAL_MACHINE',
@key='Software\Microsoft\Microsoft SQL Server\MSSQL10.SQL2008\MSSQLServer',
