探討:如何查看和獲取SQL Server實例名

更新時間：2013年06月11日 14:48:03 作者：

本篇文章是對如何查看和獲取SQL Server實例名進(jìn)行了詳細(xì)的分析介紹，需要的朋友參考下

一、查看實例名時可用

1、服務(wù)—SQL Server(實例名)，默認(rèn)實例為(MSSQLSERVER)

或在連接企業(yè)管理時-查看本地實例

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

3、用命令
sqlcmd/osql
sqlcmd -L
sqlcmd -Lc
osql -L

獲取可用實例,以下舉一個例子，根據(jù)自己情況改

復(fù)制代碼代碼如下:

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(jù)實例命名規(guī)則判斷

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

二、

--1.
SELECT SERVERPROPERTY('InstanceName')

--2
sp_helpserver

--3
select @@SERVERNAME

--4
SELECT * FROM SYS.SYSSERVERS

--5
SELECT * 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 Case
When SERVERPROPERTY ('InstanceName') Is Null Then @@SERVERNAME
Else SERVERPROPERTY ('InstanceName')
End

五、在本地或網(wǎng)絡(luò)得到所有實例名

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

復(fù)制代碼代碼如下:

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);
           }
        }
      }
    }
}

2、You can use SQLDMO.dll to retrieve the list of SQL Server instances. The SQLDMO.dll can be found from the "C:/Program Files/Microsoft SQL Server/80/Tools/Bin" folder. Refer this assembly in your project and the following snippet would return a List Object containing the sql server instances.

復(fù)制代碼代碼如下:

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