function Test-DbaDbCompatibility { <# .SYNOPSIS Compares Database Compatibility level to Server Compatibility .DESCRIPTION Compares Database Compatibility level to Server Compatibility .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER Credential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .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 Detailed Will be deprecated in 1.0.0 release. .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 Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Test-DbaDbCompatibility .EXAMPLE Test-DbaDbCompatibility -SqlInstance sqlserver2014a Returns server name, database name and true/false if the compatibility level match for all databases on sqlserver2014a. .EXAMPLE 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 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 Get-DbaRegisteredServer -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 = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$Credential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [switch]$Detailed, [Alias('Silent')] [switch]$EnableException ) begin { Test-DbaDeprecation -DeprecatedOn "1.0.0" -Parameter "Detailed" } process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Connecting to $instance." try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential -MinimumVersion 10 } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $serverversion = "Version$($server.VersionMajor)0" $dbs = $server.Databases | Where-Object IsAccessible if ($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."
