——T-SQL查询查找机器上已安装的实例列表

DECLARE @GetInstances TABLE
( Value nvarchar(100),
 InstanceNames nvarchar(100),
 Data nvarchar(100))

Insert into @GetInstances
EXECUTE xp_regread
  @rootkey = 'HKEY_LOCAL_MACHINE',
  @key = 'SOFTWARE\Microsoft\Microsoft SQL Server',
  @value_name = 'InstalledInstances'

Select InstanceNames from @GetInstances 

SQL Server permits applications to find SQL Server instances within the current network. The SqlDataSourceEnumerator class exposes this information to the application developer, providing a DataTable containing information about all the visible servers. This returned table contains a list of server instances available on the network that matches the list provided when a user attempts to create a new connection, and expands the drop-down list containing all the available servers on the Connection Properties dialog box. The results displayed are not always complete. In order to retrieve the table containing information about the available SQL Server instances, you must first retrieve an enumerator, using the shared/static Instance property:

using System.Data.Sql;

class Program
{
  static void Main()
  {
    // Retrieve the enumerator instance and then the data.
    SqlDataSourceEnumerator instance =
      SqlDataSourceEnumerator.Instance;
    System.Data.DataTable table = instance.GetDataSources();

    // Display the contents of the table.
    DisplayData(table);

    Console.WriteLine("Press any key to continue.");
    Console.ReadKey();
  }

  private static void DisplayData(System.Data.DataTable table)
  {
    foreach (System.Data.DataRow row in table.Rows)
    {
      foreach (System.Data.DataColumn col in table.Columns)
      {
        Console.WriteLine("{0} = {1}", col.ColumnName, row[col]);
      }
      Console.WriteLine("============================");
    }
  }
}

当我评估100多个服务器时，我也遇到了同样的问题，我用c#写了一个脚本来浏览由SQL组成的服务名称。当在服务器上安装实例时，SQL server为每个实例添加一个服务，并使用服务名。对于不同的版本，例如2000年到2008年，它可能有所不同，但肯定有一个具有实例名的服务。

我获取服务名并从服务名获得实例名。下面是WMI查询结果的示例代码:

if (ServiceData.DisplayName == "MSSQLSERVER" || ServiceData.DisplayName == "SQL Server (MSSQLSERVER)")
            {
                InstanceData.Name = "DEFAULT";
                InstanceData.ConnectionName = CurrentMachine.Name;
                CurrentMachine.ListOfInstances.Add(InstanceData);
            }
            else
                if (ServiceData.DisplayName.Contains("SQL Server (") == true)
                {
                    InstanceData.Name = ServiceData.DisplayName.Substring(
                                            ServiceData.DisplayName.IndexOf("(") + 1,
                                            ServiceData.DisplayName.IndexOf(")") - ServiceData.DisplayName.IndexOf("(") - 1
                                        );
                    InstanceData.ConnectionName = CurrentMachine.Name + "\\" + InstanceData.Name;
                    CurrentMachine.ListOfInstances.Add(InstanceData);
                }
                else
                    if (ServiceData.DisplayName.Contains("MSSQL$") == true)
                    {
                        InstanceData.Name = ServiceData.DisplayName.Substring(
                                                ServiceData.DisplayName.IndexOf("$") + 1,
                                                ServiceData.DisplayName.Length - ServiceData.DisplayName.IndexOf("$") - 1
                                            );

                        InstanceData.ConnectionName = CurrentMachine.Name + "\\" + InstanceData.Name;
                        CurrentMachine.ListOfInstances.Add(InstanceData);
                    }

如果你在SSMS内，你可能会发现它更容易使用:

SELECT @@Version

我知道这是一个老帖子，但我发现了一个很好的解决方案与PoweShell，你可以找到SQL实例安装在本地或远程机器上，包括版本，也可以扩展获得其他属性。

$MachineName = ‘.’ # Default local computer Replace . with server name for a remote computer

$reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey(‘LocalMachine’, $MachineName)
$regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" )
$values = $regkey.GetValueNames()
$values | ForEach-Object {$value = $_ ; $inst = $regKey.GetValue($value); 
              $path = "SOFTWARE\\Microsoft\\Microsoft SQL Server\\"+$inst+"\\MSSQLServer\\"+"CurrentVersion";
              #write-host $path; 
              $version = $reg.OpenSubKey($path).GetValue("CurrentVersion");
                          write-host "Instance" $value;
              write-host  "Version" $version}

这里有一个简单的方法: 去 然后开始 程序然后 然后是SQL Server 2005 配置工具 然后是SQL Server配置管理器 然后进行SQL Server 2005网络配置 在这里，您可以找到安装到您的机器上的所有实例。
