If you just want to see what's installed on the machine you're currently logged in to, I think the most straightforward manual process is to just open the SQL Server Configuration Manager (from the Start menu), which displays all the SQL Services (and only SQL services) on that hardware (running or not). This assumes SQL Server 2005, or greater; dotnetengineer's recommendation to use the Services Management Console will show you all services, and should always be available (if you're running earlier versions of SQL Server, for example).

If you're looking for a broader discovery process, however, you might consider third party tools such as SQLRecon and SQLPing, which will scan your network and build a report of all SQL Service instances found on any server to which they have access. It's been a while since I've used tools like this, but I was surprised at what they found (namely, a handful of instances that I didn't know existed). YMMV. You might Google for details, but I believe this page has the relevant downloads: http://www.sqlsecurity.com/Tools/FreeTools/tabid/65/Default.aspx

在Windows命令行中输入:

SC \\server_name query | find /I "SQL Server ("

其中“server_name”是希望在其上显示SQL实例的任何远程服务器的名称。

当然，这需要足够的权限。

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}

另一个选择是运行SQLSERVER发现报告，进入SQLSERVER安装介质，双击setup.exe

在下一个屏幕中，转到工具并单击如下所示的发现报告

这将向你展示所有的实例以及整个功能..下面是我电脑上的快照

你可以查询这个注册表值直接得到SQL版本:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\ClientSetup\CurrentVersion

或者你可以查询你的实例名，然后使用sqlcmd和你想要的实例名:

要查看实例名:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names

然后执行这个:

SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')

如果您使用c++，您可以使用这段代码来获取注册表信息。

这个查询可以得到服务器名和实例名:

SELECT @@SERVERNAME, @@SERVICENAME
