SQL相关路径查询脚本

--1.查询机器名
SELECT @@servername AS 机器名称
--查询已安装的SQL实例名
SELECT *
FROM   Sys.Servers--2.查询SQL安装路径
DECLARE @installPath VARCHAR(200) 
EXEC MASTER.dbo.xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\MSSQLSERVER\setup','SQLPath',@installPath OUTPUTSET @installPath = @installPath + '\data\' 
PRINT @installPath--3.得到SQL中的各种目录
DECLARE @path VARCHAR(8000)--3.1得到当前数据库的数据文件路径
SELECT @path = RTRIM(REVERSE(FILENAME))
FROM   sysfiles
SELECT @path = REVERSE(SUBSTRING(@path, CHARINDEX('\', @path), 8000))
SELECT 数据文件目录 = @path--3.2得到SQL安装时设置的数据文件路径
SELECT @path = RTRIM(REVERSE(FILENAME))
FROM   MASTER..sysfiles
WHERE  NAME = 'master'SELECT @path = REVERSE(SUBSTRING(@path, CHARINDEX('\', @path), 8000))
SELECT SQL数据文件目录 = @path--3.3根据安装路径得到默认的备份目录:
SELECT @path = RTRIM(REVERSE(FILENAME))
FROM   MASTER..sysfiles
WHERE  NAME = 'master'SELECT @path = SUBSTRING(@path, CHARINDEX('\', @path) + 1, 8000),@path = REVERSE(SUBSTRING(@path, CHARINDEX('\', @path), 8000)) + 'BACKUP\'
SELECT SQL数据默认备份目录 = @path
