function Remove-DbaDatabaseCertificate { <# .SYNOPSIS Deletes specified database certificate .DESCRIPTION Deletes specified database certificate .PARAMETER SqlInstance The SQL Server to create the certificates on. .PARAMETER SqlCredential Allows you to login to SQL Server using alternative credentials. .PARAMETER Database The database where the certificate will be removed. .PARAMETER Certificate The certificate that will be removed .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .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. .PARAMETER CertificateCollection Internal parameter to support pipeline input .NOTES Tags: Certificate Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .EXAMPLE Remove-DbaDatabaseCertificate -SqlInstance Server1 The certificate in the master database on server1 will be removed if it exists. .EXAMPLE Remove-DbaDatabaseCertificate -SqlInstance Server1 -Database db1 -Confirm:$false Suppresses all prompts to remove the certificate in the 'db1' database and drops the key. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true, ConfirmImpact = "High")] param ( [parameter(Mandatory, ParameterSetName = "instance")] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [parameter(Mandatory, ParameterSetName = "instance")] [object[]]$Database, [parameter(Mandatory, ParameterSetName = "instance")] [object[]]$Certificate, [parameter(ValueFromPipeline, ParameterSetName = "collection")] [Microsoft.SqlServer.Management.Smo.Certificate[]]$CertificateCollection, [switch][Alias('Silent')]$EnableException ) begin { function drop-cert ($smocert) { $server = $smocert.Parent.Parent $instance = $server.DomainInstanceName $cert = $smocert.Name $db = $smocert.Parent.Name if ($Pscmdlet.ShouldProcess($instance, "Dropping the certificate named $cert for database '$db' on $instance")) { try { $smocert.Drop() Write-Message -Level Verbose -Message "Successfully removed certificate named $cert from the $db database on $instance" [pscustomobject]@{ ComputerName = $server.NetName InstanceName = $server.ServiceName SqlInstance = $instance Database = $db Certificate = $cert Status = "Success" } } catch { [pscustomobject]@{ ComputerName = $server.NetName InstanceName = $server.ServiceName SqlInstance = $instance Database = $db Certificate = $cert Status = "Failure" } Stop-Function -Message "Failed to drop certificate named $cert from $db on $instance." -Target $smocert -InnerErrorRecord $_ -Continue } } } } process { foreach ($instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $sqlcredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } foreach ($db in $Database) { $smodb = $server.Databases[$db] if ($null -eq $smodb) { Stop-Function -Message "Database '$db' does not exist on $instance" -Target $smodb -Continue } foreach ($cert in $certificate) { $smocert = $smodb.Certificates[$cert] if ($null -eq $smocert) { Stop-Function -Message "No certificate named $cert exists in the $db database on $instance" -Target $smodb.Certificates -Continue } Drop-Cert -smocert $smocert } } } foreach ($smocert in $CertificateCollection) { Drop-Cert -smocert $smocert } } } |
