function Get-DbaServerRole { <# .SYNOPSIS Gets the list of server-level roles. .DESCRIPTION Gets the list of server-level roles for SQL Server instance. .PARAMETER SqlInstance The target SQL Server instance or instances. Server version must be SQL Server version 2005 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER ServerRole Server-Level role to filter results to that role only. .PARAMETER ExcludeServerRole Server-Level role to exclude from results. .PARAMETER ExcludeFixedRole Filter the fixed server-level roles. Only applies to SQL Server 2017 that supports creation of server-level roles. .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: ServerRole, Security Author: Shawn Melton (@wsmelton) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaServerRole .EXAMPLE PS C:\> Get-DbaServerRole -SqlInstance sql2016a Outputs list of server-level roles for sql2016a instance. .EXAMPLE PS C:\> Get-DbaServerRole -SqlInstance sql2017a -ExcludeFixedRole Outputs the server-level role(s) that are not fixed roles on sql2017a instance. #> [CmdletBinding()] param ( [Parameter(Position = 0, Mandatory, ValueFromPipeline)] [DbaInstance[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$ServerRole, [string[]]$ExcludeServerRole, [switch]$ExcludeFixedRole, [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $serverroles = $server.Roles if ($ServerRole) { $serverroles = $serverroles | Where-Object Name -In $ServerRole } if ($ExcludeServerRole) { $serverroles = $serverroles | Where-Object Name -NotIn $ExcludeServerRole } if ($ExcludeFixedRole) { $serverroles = $serverroles | Where-Object IsFixedRole -eq $false } foreach ($role in $serverroles) { $members = $role.EnumMemberNames() Add-Member -Force -InputObject $role -MemberType NoteProperty -Name Login -Value $members Add-Member -Force -InputObject $role -MemberType NoteProperty -Name ComputerName -value $server.ComputerName Add-Member -Force -InputObject $role -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $role -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName $default = 'ComputerName', 'InstanceName', 'SqlInstance', 'Name as Role', 'Login', 'IsFixedRole', 'DateCreated', 'DateModified' Select-DefaultView -InputObject $role -Property $default } } } } |
