如何确定已安装的SQL Server实例及其版本?

我试图确定我已经安装的sql server/sql express的实例(手动或编程)，但所有的例子都告诉我运行一个sql查询来确定这假设我已经连接到一个特定的实例。

我也有同样的问题。“osql -L”命令只显示服务器列表，但不显示实例名(只显示本地SQL server的实例)。通过Wireshark, sqlbrowser.exe(可以在SQL安装的共享文件夹中找到)，我找到了解决我的问题的方法。

本地实例由注册表项解析。远程实例通过UDP广播(端口1434)和SMB进行解析。使用"sqlbrowser.exe -c"列出请求。

My configuration uses 1 physical and 3 virtual network adapters. If I used the "osql -L" command the sqlbrowser displayed a request from one of the virtual adaptors (which is in another network segment), instead of the physical one. osql selects the adpater by its metric. You can see the metric with command "route print". For my configuration the routing table showed a lower metric for teh virtual adapter then for the physical. So I changed the interface metric in the network properties by deselecting automatic metric in the advanced network settings. osql now uses the physical adapter.

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

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);
                    }

这个查询可以得到服务器名和实例名:
