function Get-DbaBuildReference { <# .SYNOPSIS Returns SQL Server Build infos on a SQL instance .DESCRIPTION Returns info about the specific build of a SQL instance, including the SP, the CU and the reference KB, wherever possible. It also includes End Of Support dates as specified on Microsoft Lifecycle Policy .PARAMETER Build Instead of connecting to a real instance, pass a string identifying the build to get the info back. .PARAMETER SqlInstance Target any number of instances, in order to return their build state. .PARAMETER SqlCredential When connecting to an instance, use the credentials specified. .PARAMETER Update Looks online for the most up to date reference, replacing the local one. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .EXAMPLE Get-DbaBuildReference -Build "12.00.4502" Returns information about a build identified by "12.00.4502" (which is SQL 2014 with SP1 and CU11) .EXAMPLE Get-DbaBuildReference -Build "12.00.4502" -Update Returns information about a build trying to fetch the most up to date index online. When the online version is newer, the local one gets overwritten .EXAMPLE Get-DbaBuildReference -Build "12.0.4502","10.50.4260" Returns information builds identified by these versions strings .EXAMPLE Get-DbaRegisteredServer -SqlInstance sqlserver2014a | Get-DbaBuildReference Integrate with other commandlets to have builds checked for all your registered servers on sqlserver2014a .NOTES Author: niphlod Editor: Fred Tags: SqlBuild dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaBuildReference #> [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseShouldProcessForStateChangingFunctions", "")] [CmdletBinding()] Param ( [version[]] $Build, [parameter(Mandatory = $false, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]] $SqlInstance, [Alias("Credential")] [PsCredential] $SqlCredential, [switch] $Update, [switch] [Alias('Silent')]$EnableException ) begin { #region Helper functions function Get-DbaBuildReferenceIndex { [CmdletBinding()] Param ( [string] $Moduledirectory, [bool] $Update, [bool] $EnableException ) $orig_idxfile = "$Moduledirectory\bin\dbatools-buildref-index.json" $DbatoolsData = Get-DbatoolsConfigValue -Name 'Path.DbatoolsData' $writable_idxfile = Join-Path $DbatoolsData "dbatools-buildref-index.json" if (-not (Test-Path $orig_idxfile)) { Write-Message -Level Warning -Message "Unable to read local SQL build reference file.
