Bagaimana saya bisa tahu apakah contoh SQL Server saya ditambal? Apakah ada fungsi asli yang akan mengidentifikasi apakah ada tambalan yang tersedia untuk server saya? Heck, apakah saya bahkan memiliki data versi yang tersedia untuk saya?

Untuk menjawab dalam urutan terbalik

Versi apa yang saya pakai?

Ada dua pertanyaan berbeda yang saya gunakan untuk mengidentifikasi tingkat SQL Server saya.

Yang pertama adalah versi @@ . Yang menyenangkan tentang ini adalah ia membawa kembali informasi tingkat OS juga. Tantangannya adalah itu adalah tumpukan teks yang besar dan Anda harus menguraikannya untuk menemukan bit yang relevan.

misalnya

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)
*/

Preferensi saya adalah menggunakan ServerPropertieskarena saya dapat mengidentifikasi elemen secara individual.

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)
*/

Apakah ada fungsi asli untuk memeriksa patch?

Tidak ada yang saya sadari. Jika OS host menjalankan layanan Pembaruan Windows dan seseorang telah menetapkan "Sertakan tambalan untuk produk MS lainnya" maka Anda mungkin mendapatkan tambalan yang diinstal untuk SQL Server.

Tetapi, jika Anda seorang profesional, Anda mungkin tidak tertarik menunggu tambalan terdaftar di WSUS atau Anda ingin memvalidasi bahwa tambalan bekerja untuk lingkungan Anda. Itu akan melibatkan membaca artikel basis pengetahuan (KB) dan pengujian.

Bagaimana saya bisa tahu jika instance SQL Server saya ditambal?

Karena tidak memiliki apa pun yang ada di dalam produk, saya telah mereferensikan sqlserverbuilds.blogspot.com . Tetapi ada banyak situs lain di luar sana yang mencoba menawarkan daftar tambalan terkonsolidasi yang sama, seperti:

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

Saya telah mengambil data dari blog itu dan mengonversinya menjadi Tampilan, dbo.PatchLevel. Pandangan itu memperlihatkan semua tambalan. Pandangan ini terpotong untuk hanya mencakup 2016 dan 2014, kalau tidak, saya meniup batas karakter untuk jawaban.

Saya memiliki pandangan kedua, ya tampilan bersarang - buruk saya, dbo.MyPatchLevel yang menggunakan data versi dari atas untuk membandingkan dengan contoh saya saat ini dan menghasilkan output untuk memberi tahu saya betapa buruknya itu.

CREATE VIEW dbo.MyPatchLevel
AS
WITH MostRecentBuild AS

    SELECT
        SRC.Build
    ,   SRC.[Release Date]
    ,   SRC.SimpleVersion

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

            SRCI.SimpleVersion = SRC.SimpleVersion

Saya akan menggunakan kueri seperti

SELECT

,   MPL.[Release Date]
,   MPL.MostRecentReleaseDate
,   MPL.DaysSincePatchAvailable
,   MPL.[Most Recent KB / Description]

Hasil

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

Dipersenjatai dengan hasil kueri ini, saya tahu apakah saya ditambal terbaru, sudah berapa lama sejak saya ditambal dan berapa KB yang harus dibaca tentang keadaan tambalan saat ini.
