#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Add-DbaAgDatabase { <# .SYNOPSIS Adds a database to an availability group on a SQL Server instance. .DESCRIPTION Adds a database to an availability group on a SQL Server instance. .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher. .PARAMETER SqlCredential Login to the SqlInstance instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database The database or databases to add. .PARAMETER AvailabilityGroup The availability group where the databases will be added. .PARAMETER InputObject Enables piping from Get-DbaDatabase, Get-DbaDbSharePoint and more. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .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: AvailabilityGroup, HA, AG Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Add-DbaAgDatabase .EXAMPLE PS C:\> Add-DbaAgDatabase -SqlInstance sql2017a -AvailabilityGroup ag1 -Database db1, db2 -Confirm Adds db1 and db2 to ag1 on sql2017a.
