探讨:如何查看和获取SQL Server实例名

这篇文章主要为大家详细介绍了探讨:如何查看和获取SQL Server实例名，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

一、查看實例名時可用

1、服务—SQL Server(实例名)，默认实例为(MSSQLSERVER)

或在连接企业管理时-查看本地实例

2、通過注冊表HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Microsoft SQL Server/InstalledInstance

3、用命令sqlcmd/osqlsqlcmd -Lsqlcmd -Lcosql -L

获取可用實例,以下舉一個例子，根據自己情況改

代码如下:

DECLARE @Table TABLE ( instanceName  sysname NULL)

insert @Table EXEC sys.xp_cmdshell 'sqlcmd -Lc'

--LEFT(@@serverName,CHARINDEX('/',@@serverName+'/')-1) 替代為本機名就行了 , 根據實例命名規則判斷

SELECT * FROM @Table WHERE instanceName LIKE LEFT( @@serverName , CHARINDEX ( '/' , @@serverName + '/' )- 1)+ '%'

--1. SELECT SERVERPROPERTY('InstanceName')

--2sp_helpserver

--3select @@SERVERNAME

--4SELECT * FROM SYS.SYSSERVERS

--5SELECT * FROM SYS.SERVERS

三、

EXECUTE xp_regread @rootkey='HKEY_LOCAL_MACHINE',@key='SOFTWARE/Microsoft/Microsoft SQL Server/Instance Names/SQl',@value_name='MSSQLSERVER'

四、

Select CaseWhen SERVERPROPERTY ('InstanceName') Is Null Then @@SERVERNAMEElse SERVERPROPERTY ('InstanceName')End

五、在本地或网络得到所有实例名

1、You can do with registry reading , like my code

代码如下:

using System;
using Microsoft.Win32;

namespace SMOTest{ class Program { static void Main() { RegistryKey rk = Registry.LocalMachine.OpenSubKey(@"SOFTWARE/Microsoft/Microsoft SQL Server"); String[] instances = (String[])rk.GetValue("InstalledInstances"); if (instances.Length > 0) { foreach (String element in instances) { if (element == "MSSQLSERVER") Console.WriteLine(System.Environment.MachineName); else Console.WriteLine(System.Environment.MachineName + @"/" + element); } } } }}

代码如下:

public static List GetSQLServerInstances() 
{
NameList sqlNameList = null;
Application app = null;

var sqlServers = new List();try{app = new ApplicationClass();sqlNameList = app.ListAvailableSQLServers();foreach (string sqlServer in sqlNameList)sqlServers.Add(sqlServer);}catch(Exception ex){//play with the exception.}finally{if (sqlNameList != null)sqlNameList = null;if (app != null)app = null;}return sqlServers;}
