function Test-DbaBuild { <# .SYNOPSIS Returns SQL Server Build "compliance" level on a build .DESCRIPTION It answers the question "is this build up to date ?" Returns info about the specific build of a SQL instance, including the SP, the CU and the reference KB, End Of Support, wherever possible. It adds a Compliance property as true/false, and adds details about the "targeted compliance" .PARAMETER Build Instead of connecting to a real instance, pass a string identifying the build to get the info back. .PARAMETER MinimumBuild This is the build version to test "compliance" against. Anything below this is flagged as not compliant .PARAMETER MaxBehind Instead of using a specific MinimumBuild here you can pass "how many service packs and cu back" is the targeted compliance level You can use xxSP or xxCU or both, where xx is a number. See Examples for more informations .PARAMETER Latest Shortcut for specifying the very most up-to-date build available. .PARAMETER SqlInstance Target any number of instances, in order to return their compliance 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 Quiet Makes the function just return $true/$false. It's useful if you use Test-DbaBuild in your own scripts, like if (Test-DbaBuild -Build "12.0.5540" -MaxBehind "0CU" -Quiet) { Do-Something } .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 Test-DbaBuild -Build "12.0.5540" -MinimumBuild "12.0.5557" Returns information about a build identified by "12.0.5540" (which is SQL 2014 with SP2 and CU4), which is not compliant as the minimum required build is "12.0.5557" (which is SQL 2014 with SP2 and CU8) .EXAMPLE Test-DbaBuild -Build "12.0.5540" -MaxBehind "1SP" Returns information about a build identified by "12.0.5540", making sure it is AT MOST 1 Service Pack "behind". For that version, that identifies an SP2, means accepting as the lowest compliance version as "12.0.4110", that identifies 2014 with SP1 .EXAMPLE Test-DbaBuild -Build "12.0.5540" -MaxBehind "1SP 1CU" Returns information about a build identified by "12.0.5540", making sure it is AT MOST 1 Service Pack "behind", plus 1 CU "behind". For that version, that identifies an SP2 and CU, rolling back 1 SP brings you to "12.0.4110", but given the latest CU for SP1 is CU13, the target "compliant" build will be "12.0.4511", which is 2014 with SP1 and CU12 .EXAMPLE Test-DbaBuild -Build "12.0.5540" -MaxBehind "0CU" Returns information about a build identified by "12.0.5540", making sure it is the latest CU release. .EXAMPLE Test-DbaBuild -Build "12.0.5540" -Latest Same as previous, returns information about a build identified by "12.0.5540", making sure it is the latest build available. .EXAMPLE Test-DbaBuild -Build "12.00.4502" -MinimumBuild "12.0.4511" -Update Same as before, but tries to fetch the most up to date index online. When the online version is newer, the local one gets overwritten .EXAMPLE Test-DbaBuild -Build "12.0.4502","10.50.4260" -MinimumBuild "12.0.4511" Returns information builds identified by these versions strings .EXAMPLE Get-DbaRegisteredServer -SqlInstance sqlserver2014a | Test-DbaBuild -MinimumBuild "12.0.4511" 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/Test-DbaBuild #> [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseShouldProcessForStateChangingFunctions", "")] [CmdletBinding()] param ( [version[]] $Build, [version] $MinimumBuild, [string] $MaxBehind, [switch] $Latest, [parameter(Mandatory = $false, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]] $SqlInstance, [Alias("Credential")] [PSCredential] $SqlCredential, [switch] $Update, [switch] $Quiet, [switch] [Alias('Silent')]$EnableException ) begin { #region Helper functions function Get-DbaBuildReferenceIndex { [CmdletBinding()] $DbatoolsData = Get-DbatoolsConfigValue -Name 'Path.DbatoolsData' $writable_idxfile = Join-Path $DbatoolsData "dbatools-buildref-index.json" $result = Get-Content $writable_idxfile -Raw | ConvertFrom-Json $result.Data | Select-Object @{ Name = "VersionObject"; Expression = { [version]$_.Version } }, * } $ComplianceSpec = @() $ComplianceSpecExclusiveParams = @('MinimumBuild', 'MaxBehind', 'Latest') foreach ($exclParam in $ComplianceSpecExclusiveParams) { if (Test-Bound -Parameter $exclParam) { $ComplianceSpec += $exclParam } } if ($ComplianceSpec.Length -gt 1) { Stop-Function -Category InvalidArgument -Message "-MinimumBuild, -MaxBehind and -Latest are mutually exclusive.
