以相反的顺序回答
我使用两个不同的查询来标识我的SQL Server级别。
第一个是@@ version。这样做的好处是它还可以带回操作系统级别的信息。它面临的挑战是大量的文本转储，您必须对其进行解析以找到相关的位。
例如
SELECT @@version;
/*
Microsoft SQL Server 2014 - 12.0.4416.0 (X64)
Jun 11 2015 19:18:41
Copyright (c) Microsoft Corporation
Developer Edition (64-bit) on Windows NT 6.3 <X64> (Build 9600: ) (Hypervisor)
*/
我更喜欢使用，ServerProperties因为我可以单独识别元素。
SELECT
SERVERPROPERTY('productversion') AS ProductVersion
, SERVERPROPERTY ('productlevel') AS ProductLevel
, SERVERPROPERTY ('edition') AS Edition;
/*
ProductVersion ProductLevel Edition
12.0.4416.0 SP1 Developer Edition (64-bit)
*/
我什么都不知道。如果主机操作系统正在运行Windows Update服务，并且有人指定“包括其他MS产品的修补程序”，则可能会安装SQL Server的修补程序。
但是，如果您是专业人士，则可能对等待WSUS中列出的补丁不感兴趣，或者想验证该补丁是否适合您的环境。这将涉及阅读知识库（KB）文章和测试。
缺少产品中内置的任何内容，我一直在引用sqlserverbuilds.blogspot.com。但是，还有许多其他站点试图提供相同的合并补丁列表，例如：
我已经从该博客中获取了数据，并将其转换为一个视图dbo.PatchLevel。该视图显示了所有补丁。该视图被截断为仅涵盖2016年和2014年，否则我吹了字符数限制以寻求答案。

我有第二个视图，是嵌套视图-不好意思，dbo.MyPatchLevel，它使用上面的版本数据与我的当前实例进行比较，并生成输出以让我知道它的严重程度。

WHERE
SRCI.SimpleVersion = SRC.SimpleVersion
)
AND
SRC.Build =

SELECT

WHERE
SRCI.SimpleVersion = SRC.SimpleVersion
AND SRCI.[Release Date] = SRC.[Release Date]

我会使用类似的查询

, MPL.[Release Date]

, MPL.DaysSincePatchAvailable
, MPL.[Most Recent KB / Description]
FROM

结果

有了这些查询结果，我就知道我是否已对补丁进行了更新，自补丁以来已经进行了多长时间以及要在当前补丁状态下读取多少KB。
