Question

我想将以下脚本提供给我的客户端以安装新数据库如何重写这部分脚本以反映其特定数据和日志文件位置：

USE [master]
GO
/****** Object:  Database [PhoneBook]    Script Date: 2016/1/13 11:02:34 AM ******/
CREATE DATABASE [PhoneBook]
 CONTAINMENT = NONE
 ON  PRIMARY 
( NAME = N'PhoneBook', FILENAME = N'C:\Program Files (x86)\Microsoft SQL Server\MSSQL12.SQLEXPRESS\MSSQL\DATA\PhoneBook.mdf' , SIZE = 5120KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'PhoneBook_log', FILENAME = N'C:\Program Files (x86)\Microsoft SQL Server\MSSQL12.SQLEXPRESS\MSSQL\DATA\PhoneBook_log.ldf' , SIZE = 2048KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)
GO

我客户的Windows驱动器不是c。
我可以更改这些路径以反映其sql安装路径吗？我怎么能告诉这个脚本找到合适的位置？

Answer 1

对于SQL Server 2012及更高版本，只要在服务器级别设置了默认数据和日志文件目录，就可以使用这些服务器属性here。你可以使用动态sql做这样的事情：

USE [master]
GO

DECLARE @defaultDataPath NVARCHAR(MAX) = CONVERT(VARCHAR(MAX), SERVERPROPERTY('InstanceDefaultDataPath'))
DECLARE @defaultLogPath NVARCHAR(MAX) = CONVERT(VARCHAR(MAX), SERVERPROPERTY('InstanceDefaultLogPath'))
DECLARE @sql NVARCHAR(MAX) = 

'CREATE DATABASE [PhoneBook]
 CONTAINMENT = NONE
 ON  PRIMARY 
( NAME = N''PhoneBook'', FILENAME = N''' + @defaultDataPath + 'PhoneBook.mdf'' , SIZE = 5120KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N''PhoneBook_log'', FILENAME = N''' + @defaultLogPath + 'PhoneBook_log.ldf'' , SIZE = 2048KB , MAXSIZE = 2048GB , FILEGROWTH = 10%) '

PRINT @sql
EXEC (@sql)

USE [master]
GO

DECLARE @mdfPath NVARCHAR(max), @ldfPath NVARCHAR(max) , @SQL NVARCHAR(MAX), @instName NVARCHAR(max) = 'PhoneBook'


SELECT @mdfPath = SUBSTRING(physical_name, 1,CHARINDEX(N'master.mdf',LOWER(physical_name)) - 1)+@instName+N'.mdf'
       ,@ldfPath = SUBSTRING(physical_name, 1,CHARINDEX(N'master.mdf',LOWER(physical_name)) - 1)+@instName+N'.ldf'
FROM master.sys.master_files
WHERE database_id = 1 AND FILE_ID = 1


SELECT @SQL =
'CREATE DATABASE [PhoneBook]
 CONTAINMENT = NONE
 ON  PRIMARY 
( NAME = N'''+@instName+''', FILENAME = N'''+@mdfPath+''' , SIZE = 5120KB , MAXSIZE = UNLIMITED, FILEGROWTH = 1024KB )
 LOG ON 
( NAME = N'''+@instName+'_log'', FILENAME = N'''+@ldfPath+''' , SIZE = 2048KB , MAXSIZE = 2048GB , FILEGROWTH = 10%)'

PRINT(@SQL)
EXECUTE(@SQL)

GO
