function Get-DbaDbRoleMember { <# .SYNOPSIS Get members of database roles for each instance(s) of SQL Server. .DESCRIPTION The Get-DbaDbRoleMember returns connected SMO object for database roles for each instance(s) of SQL Server. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Login to the target instance using alternate Windows or SQL Login Authentication. Accepts credential objects (Get-Credential). .PARAMETER Database The database(s) to process. This list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude. This list is auto-populated from the server. .PARAMETER Role The role(s) to process. If unspecified, all roles will be processed. .PARAMETER ExcludeRole The role(s) to exclude. .PARAMETER ExcludeFixedRole Excludes all members of fixed roles. .PARAMETER IncludeSystemUser Includes system users. By default system users are not included. .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: Role, Database, Security, Login Author: Klaas Vandenberghe (@PowerDBAKlaas) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT - License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDbRoleMember .EXAMPLE PS C:\> Get-DbaDbRoleMember -SqlInstance localhost Returns all members of all database roles on the local default SQL Server instance .EXAMPLE PS C:\> Get-DbaDbRoleMember -SqlInstance localhost, sql2016 Returns all members of all database roles on the local and sql2016 SQL Server instances .EXAMPLE PS C:\> $servers = Get-Content C:\servers.txt PS C:\> $servers | Get-DbaDbRoleMember Returns all members of all database roles for every server in C:\servers.txt .EXAMPLE PS C:\> Get-DbaDbRoleMember -SqlInstance localhost -Database msdb Returns non-system members of all roles in the msdb database on localhost. .EXAMPLE PS C:\> Get-DbaDbRoleMember -SqlInstance localhost -Database msdb -IncludeSystemUser -ExcludeFixedRole Returns all members of non-fixed roles in the msdb database on localhost. .EXAMPLE PS C:\> Get-DbaDbRoleMember -SqlInstance localhost -Database msdb -Role 'db_owner' Returns all members of the db_owner role in the msdb database on localhost. #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstance[]]$SqlInstance, [Alias("Credential")] [PSCredential]$SqlCredential, [string[]]$Database, [string[]]$ExcludeDatabase, [string[]]$Role, [string[]]$ExcludeRole, [switch]$ExcludeFixedRole, [switch]$IncludeSystemUser, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Attempting to connect to $instance" try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message 'Failure' -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $databases = $server.Databases | Where-Object { $_.IsAccessible -eq $true } if (Test-Bound -Parameter 'Database') { $databases = $databases | Where-Object { $_.Name -in $Database } } if (Test-Bound -Parameter 'ExcludeDatabase') { $databases = $databases | Where-Object { $_.Name -notin $ExcludeDatabase} } foreach ($db in $databases) { Write-Message -Level 'Verbose' -Message "Getting Database Roles for $db on $instance" $dbRoles = $db.roles if (Test-Bound -Parameter 'Role') { $dbRoles = $dbRoles | Where-Object { $_.Name -in $Role } } if (Test-Bound -Parameter 'ExcludeRole') { $dbRoles = $dbRoles | Where-Object { $_.Name -notin $ExcludeRole } } if (Test-Bound -Parameter 'ExcludeFixedRole') { $dbRoles = $dbRoles | Where-Object { $_.IsFixedRole -eq $false } } foreach ($dbRole in $dbRoles) { Write-Message -Level 'Verbose' -Message "Getting Database Role Members for $dbRole in $db on $instance" $members = $dbRole.EnumMembers() foreach ($member in $members) { $user = $db.Users | Where-Object { $_.Name -eq $member } if (Test-Bound -Not -ParameterName 'IncludeSystemUser') { $user = $user | Where-Object { $_.IsSystemObject -eq $false } } if ($user) { Add-Member -Force -InputObject $user -MemberType NoteProperty -Name ComputerName -Value $server.ComputerName Add-Member -Force -InputObject $user -MemberType NoteProperty -Name InstanceName -Value $server.ServiceName Add-Member -Force -InputObject $user -MemberType NoteProperty -Name SqlInstance -Value $server.DomainInstanceName Add-Member -Force -InputObject $user -MemberType NoteProperty -Name Database -Value $db.Name Add-Member -Force -InputObject $user -MemberType NoteProperty -Name Role -Value $dbRole.Name Add-Member -Force -InputObject $user -MemberType NoteProperty -Name UserName -Value $user.Name $user | Select-DefaultView -Property 'ComputerName', 'InstanceName', 'SqlInstance', 'Database', 'Role', 'UserName', 'Login' } } } } } } end { Test-DbaDeprecation -DeprecatedOn "1.0.0" -Alias Get-DbaRoleMember } } |
