倒序回答

我在哪个版本？

我使用两种不同的查询来确定我的 SQL Server 级别。

第一个是@@version。这样做的好处是它也可以返回操作系统级别的信息。它的挑战在于它是一大堆文本，您必须对其进行解析以找到相关位。

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)
*/

我的偏好是使用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)
*/

是否有检查补丁的本机功能？

没有什么我知道的。如果主机操作系统正在运行 Windows Update 服务并且有人指定了“包括其他 MS 产品的补丁”，那么您可能会为 SQL Server 安装补丁。

但是，如果您是专业人士，您可能不想等待补丁在 WSUS 中列出，或者您想要验证补丁是否适用于您的环境。这将涉及阅读知识库 (KB) 文章和测试。

如何判断我的 SQL Server 实例是否已打补丁？

由于产品中没有任何内置内容，我一直在引用sqlserverbuilds.blogspot.com。但是还有很多其他网站试图提供相同的补丁整合列表，例如：

• http://sqlserverupdates.com/
• http://blogs.sqlsentry.com/category/sql-server-builds/

我已从该博客中获取数据并将其转换为视图 dbo.PatchLevel。该视图公开了所有补丁。此视图被截断为仅涵盖 2016 年和 2014 年，否则我超出了答案的字符数限制。

CREATE VIEW dbo.PatchLevel

我有第二个视图，是的嵌套视图 - 糟糕的我，dbo.MyPatchLevel 使用上面的版本数据与我当前的实例进行比较并生成输出让我知道它有多糟糕。

    SELECT

    WHERE
        SRC.[Release Date] =
    (
        SELECT
            MAX(SRCI.[Release Date])

我会使用像这样的查询

SELECT
    MPL.CurrentVersion
,   MPL.MostRecentBuild
,   MPL.[Release Date]
,   MPL.MostRecentReleaseDate
,   MPL.DaysSincePatchAvailable
,   MPL.[Most Recent KB / Description]
FROM
    dbo.MyPatchLevel AS MPL;

结果

CurrentVersion  MostRecentBuild  Release Date  MostRecentReleaseDate  DaysSincePatchAvailable  Most Recent KB / Description
12.0.4416.0     12.0.4422.0      2015-06-22    2015-08-17             56                       3075950 Cumulative update package 2 (CU2) for SQL Server 2014 Service Pack 1

有了这些查询结果，我就知道我的补丁是否是最新的，我打补丁已经有多久了，以及要阅读当前补丁状态的知识库是什么。
