SQL Server:如何选择安装路径？

Question

我知道有一个变量,函数或存储过程可用于查找SQL Server安装到的路径:

例如:

c:\Program Files\Microsoft SQL Server\MSSQL.7\MSSQL

要么

m:\CustomInstance\MSSQL

---

实际上,我希望SELECT为默认备份路径.但由于我怀疑存在,我只是将\ BACKUP添加到安装路径并将其调得足够接近.

---

更新一

select filename from sysaltfiles
where name = db_name()

Server: Msg 208, Level 16, State 1, Line 1
Invalid object name 'sysaltfiles'.

---

select filename from master.dbo.sysaltfiles
where name = db_name()

filename

如何选择安装路径

注意:xp_instance_regread不会读取您指定的注册表项,而是将该密钥路径转换为您正在运行的特定SQL Server实例的相应路径.换句话说:xp_regread在xp_instance_regread成功的地方失败.

SQL Server安装目录

declare @rc int, @dir nvarchar(4000) 

exec @rc = master.dbo.xp_instance_regread
      N'HKEY_LOCAL_MACHINE',
      N'Software\Microsoft\MSSQLServer\Setup',
      N'SQLPath', 
      @dir output, 'no_output'
select @dir AS InstallationDirectory

SQL Server备份目录

declare @rc int, @dir nvarchar(4000) 

exec @rc = master.dbo.xp_instance_regread
      N'HKEY_LOCAL_MACHINE',
      N'Software\Microsoft\MSSQLServer\MSSQLServer',
      N'BackupDirectory', 
      @dir output, 'no_output'
select @dir AS BackupDirectory
