function Test-DbaDbCompatibility { <# .SYNOPSIS Compares Database Compatibility level to Server Compatibility .DESCRIPTION Compares Database Compatibility level to Server Compatibility .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Database Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server. .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: Database, Compatibility 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/Test-DbaDbCompatibility .EXAMPLE PS C:\> Test-DbaDbCompatibility -SqlInstance sqlserver2014a Returns server name, database name and true/false if the compatibility level match for all databases on sqlserver2014a. .EXAMPLE PS C:\> Test-DbaDbCompatibility -SqlInstance sqlserver2014a -Database db1, db2 Returns detailed information for database and server compatibility level for the db1 and db2 databases on sqlserver2014a. .EXAMPLE PS C:\> Test-DbaDbCompatibility -SqlInstance sqlserver2014a, sql2016 -Exclude db1 Returns detailed information for database and server compatibility level for all databases except db1 on sqlserver2014a and sql2016. .EXAMPLE PS C:\> Get-DbaRegServer -SqlInstance sql2014 | Test-DbaDbCompatibility Returns db/server compatibility information for every database on every server listed in the Central Management Server on sql2016. #> [CmdletBinding()] [OutputType("System.Collections.ArrayList")] param ( [parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [object[]]$Database, [object[]]$ExcludeDatabase, [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 10 } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $serverversion = "Version$($server.VersionMajor)0" $dbs = $server.Databases if ($Database) { $dbs = $dbs | Where-Object { $Database -contains $_.Name } } if ($ExcludeDatabase) { $dbs = $dbs | Where-Object Name -NotIn $ExcludeDatabase } foreach ($db in $dbs) { Write-Message -Level Verbose -Message "Processing $($db.name) on $instance."
