修改MSSQL的端口地址_TcpPort_数据库安装工具_连载_2

修改MSSQL的端口地址_TcpPort，可在程序中调用，从而修改TcpPort

Use master
Go
------------------------------
--1）在注册表中查询 PipeName，使用 xp_instance_regread可查询得到
declare @PipeName nvarchar(512)

exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\SuperSocketNetLib\Np', N'PipeName', @PipeName Output
Select @PipeName As [PipeName]

--Remark:可正常查询出结果：      PipeName
                            \\.\pipe\sql\query
--2）在注册表中查询 PipeName，使用xp_regread可查询到
declare @PipeName nvarchar(512)

exec master.dbo.xp_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\SuperSocketNetLib\Np', N'PipeName', @PipeName Output
Select @PipeName As [PipeName]
--Remark:可正常查询出结果：      PipeName
                            \\.\pipe\sql\query
---------------------------------------------------
--3）在注册表中查询 TcpPort，使用 xp_instance_regread，没有查到
declare @TcpPort nvarchar(12)

exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer\SuperSocketNetLib\Tcp', N'TcpPort', @TcpPort Output
Select @TcpPort As [TcpPort]

--使用xp_instance_regread，可正常读出端口地址  TcpPort
                                                1466
---------------------------------------------------
--4）在注册表中查询 TcpPort，使用 xp_regread，可查到
declare @rc int,@dir nvarchar(5)
exec @rc = master.dbo.xp_regread N'HKEY_LOCAL_MACHINE',N'Software\Microsoft\MSSQLServer\MSSQLServer\SuperSocketNetLib\Tcp',N'TcpPort', @dir output
select @dir as TcpPort

--@dir returns 1433
--使用xp_regread，可正常读出端口地址  TcpPort
                                                                                    1433
-----------------------------------------------------------------------------------------------------------------------------
--下面2段，只是放在一起对比，为什么获得的结果不一致（xp_regread获得的结果 1433正确）
--参考此处： https://www.sqlservercentral.com/forums/topic/xp_instance_regread
declare @rc int,@dir nvarchar(5)
exec @rc = master.dbo.xp_regread N'HKEY_LOCAL_MACHINE',N'Software\Microsoft\MSSQLServer\MSSQLServer\SuperSocketNetLib\Tcp',N'TcpPort', @dir output
select @dir as TcpPort

--使用xp_regread，可正常读出端口地址  TcpPort
                                       1466
---------------------------------------------------

 --xp_instance_regread获得结果不正确 declare @rc int,@dir nvarchar(5) exec @rc = master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE',N'Software\Microsoft\MSSQLServer\MSSQLServer\SuperSocketNetLib\Tcp',N'TcpPort', @dir output select @dir

--使用xp_instance_regread，可正常读出端口地址  TcpPort
                                                1466  (此结果与电脑中的值不一致)

---------------------------------------------------

 --路径不同，得到的结果是 2433，但这个是什么TcpPort的端口地址? declare @rc int,@dir varchar(5) exec @rc = master.dbo.xp_regread 'HKEY_LOCAL_MACHINE','SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL\MSSQLServer\SuperSocketNetLib\Tcp','TcpPort', @dir output select @dir

--使用xp_regread，读出端口地址  TcpPort
                                 2433
