SQL Server中怎么查看和獲取實例名

這篇文章將為大家詳細講解有關SQL Server中怎么查看和獲取實例名，文章內容質量較高，因此小編分享給大家做個參考，希望大家閱讀完這篇文章后對相關知識有一定的了解。

一、查看實例名時可用

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

或在連接企業管理時-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/osqlsqlcmd -Lsqlcmd -Lcosql -L

獲取可用實例,以下舉一個例子，根據自己情況改復制代碼 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 , 根據實例命名規則判斷

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

二、

--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、在本地或網絡得到所有實例名

1、You can do with registry reading , like my code復制代碼 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.復制代碼 代碼如下: 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;}
