function Test-DbaDatabaseCollation { <# .SYNOPSIS Compares Database Collations to Server Collation .DESCRIPTION Compares Database Collations to Server Collation .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER Credential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -Credential parameter. Windows Authentication will be used if Credential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .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 If this switch is enabled, full details about database & server collations and whether they match is returned. .NOTES Tags: Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Test-DbaDatabaseCollation .EXAMPLE Test-DbaDatabaseCollation -SqlInstance sqlserver2014a Returns server name, database name and true/false if the collations match for all databases on sqlserver2014a. .EXAMPLE Test-DbaDatabaseCollation -SqlInstance sqlserver2014a -Database db1, db2 Returns server name, database name and true/false if the collations match for the db1 and db2 databases on sqlserver2014a. .EXAMPLE Test-DbaDatabaseCollation -SqlInstance sqlserver2014a, sql2016 -Detailed -Exclude db1 Returns detailed information for database and server collations for all databases except db1 on sqlserver2014a and sql2016. .EXAMPLE Get-DbaRegisteredServer -SqlInstance sql2016 | Test-DbaDatabaseCollation Returns db/server collation 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 ) begin { $collection = New-Object System.Collections.ArrayList } process { foreach ($servername in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $servername -SqlCredential $Credential } catch { if ($SqlInstance.count -eq 1) { throw $_ } else { Write-Message -Level Warning -Message "Can't connect to $servername.
