如何查看SQL Server的实例名(转载)

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/osql sqlcmd -L sqlcmd -Lc osql -L

获取可用實例,以下舉一個例子,根據自己情況改

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\')
--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、在本地或网络得到所有实例名

 

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

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.

 

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;
}
