Is my SQL Server patched?

Problem

How can I tell whether my SQL Server instances are patched? Is there native functionality that will identify whether there are patches available for my server? Heck, do I even have version data available to me?

Solution

To answer in reverse order

What version am I on?

There are two different queries that I use to identify my SQL Server level.

The first is @@version. The nice thing about this is that it brings back OS level information as well. The challenge with it is that it's a big dump of text and you have to parse that to find the relevant bits.

e.g.

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  (Build 9600: ) (Hypervisor)
*/


My preference is to use ServerProperties as I can individually identify the elements.

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)
*/


Is there native functionality to check for patches?

Nothing that I'm aware of. If the host OS has Windows Update service running and someone has specified "Include patches for other MS products" then you might get patches installed for SQL Server.

But, if you're a professional, you're probably not interested in waiting for a patch to be listed in WSUS or you'd like to validate that the patch works for your environment. That's going to involve reading knowledge base (KB) articles and testing.

How can I tell if my SQL Server instances are patched?

Lacking anything built into the product, I have been referencing sqlserverbuilds.blogspot.com. But there are plenty of other sites out there attempting to offer the same consolidated list of patches, such as:

  • http://sqlserverupdates.com/



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



I have taken the data from that blog and converted it to a View, dbo.PatchLevel. That view exposes all the patches. This view is truncated to only cover 2016 and 2014, otherwise I blow the character limit for answers.

```
CREATE VIEW dbo.PatchLevel
