#ValidationTags#CodeStyle,Messaging,FlowControl,Pipeline# 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 Life Cycle 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. .NOTES Tags: SqlBuild Author: Simone Bizzotto (@niphold) | Friedrich Weinmann (@FredWeinmann) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaBuildReference .EXAMPLE PS C:\> 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 PS C:\> Get-DbaBuildReference -Build "12.00.4502" -Update Returns information about a build trying to fetch the most up to date index online.
