命令OSQL -L和sqlmd -L将显示网络上的所有实例。

如果你想要一个服务器上所有实例的列表，并且不喜欢编写脚本或编程，可以这样做:

启动Windows任务管理器 勾选“显示来自所有用户的进程”或相同的复选框 按照“映像名称”对进程进行排序 找到所有sqlsrvr.exe映像

实例应该在“用户名”列中以MSSQL$INSTANCE_NAME的形式列出。

我从认为这个可怜的服务器正在运行63个实例，到意识到它正在运行3个实例(其中一个在CPU负载方面表现得完全像个恶霸……)

这个查询可以得到服务器名和实例名:

SELECT @@SERVERNAME, @@SERVICENAME

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。

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

我知道这个帖子有点老了，但在我找到我正在寻找的答案之前，我就看到了这个帖子，我想分享一下。如果您正在使用SQLExpress(或localdb)，有一种更简单的方法来查找实例名。 在命令行类型中:

> sqllocaldb i

这将列出您在本地安装的实例名。因此，您的完整服务器名称应该在要连接的实例名称前面包含(localdb)\。此外，sqllocaldb允许您创建或删除实例以及配置它们。参见:SqlLocalDB Utility。
