function Remove-DbaDatabase { <# .SYNOPSIS Drops a database, hopefully even the really stuck ones. .DESCRIPTION Tries a bunch of different ways to remove a database or two or more. .PARAMETER SqlInstance The SQL Server instance holding the databases to be removed.You must have sysadmin access and server version must be SQL Server version 2000 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. 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 InputObject A collection of databases (such as returned by Get-DbaDatabase), to be removed. .PARAMETER IncludeSystemDb Use this switch to disable any kind of verbose messages .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. .NOTES Tags: Delete, Databases Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Remove-DbaDatabase .EXAMPLE Remove-DbaDatabase -SqlInstance sql2016 -Database containeddb Prompts then removes the database containeddb on SQL Server sql2016 .EXAMPLE Remove-DbaDatabase -SqlInstance sql2016 -Database containeddb, mydb Prompts then removes the databases containeddb and mydb on SQL Server sql2016 .EXAMPLE Remove-DbaDatabase -SqlInstance sql2016 -Database containeddb -Confirm:$false Does not prompt and swiftly removes containeddb on SQL Server sql2016 .EXAMPLE Get-DbaDatabase -SqlInstance server\instance -ExcludeAllSystemDb | Remove-DbaDatabase Removes all the user databases from server\instance .EXAMPLE Get-DbaDatabase -SqlInstance server\instance -ExcludeAllSystemDb | Remove-DbaDatabase -Confirm:$false Removes all the user databases from server\instance without any confirmation #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'High', DefaultParameterSetName = "Default")] Param ( [parameter(Mandatory, ParameterSetName = "instance")] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [parameter(Mandatory = $false)] [Alias("Credential")] [PSCredential] $SqlCredential, [parameter(Mandatory, ParameterSetName = "instance")] [Alias("Databases")] [object[]]$Database, [Parameter(ValueFromPipeline, Mandatory, ParameterSetName = "databases")] [Microsoft.SqlServer.Management.Smo.Database[]]$InputObject, [switch]$IncludeSystemDb, [Alias('Silent')] [switch]$EnableException ) process { foreach ($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 } $InputObject += $server.Databases | Where-Object { $_.Name -in $Database } } $system_dbs = @( "master", "model", "tempdb", "resource", "msdb" ) if (-not($IncludeSystemDb)) { $InputObject = $InputObject | Where-Object { $_.Name -notin $system_dbs} } foreach ($db in $InputObject) { try { $server = $db.Parent if ($Pscmdlet.ShouldProcess("$db on $server", "KillDatabase")) { $server.KillDatabase($db.name) $server.Refresh() [pscustomobject]@{ ComputerName = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.name Status = "Dropped" } } } catch { try { if ($Pscmdlet.ShouldProcess("$db on $server", "alter db set single_user with rollback immediate then drop")) { $null = $server.Query("if exists (select * from sys.databases where name = '$($db.name)' and state = 0) alter database $db set single_user with rollback immediate; drop database $db") [pscustomobject]@{ ComputerName = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.name Status = "Dropped" } } } catch { try { if ($Pscmdlet.ShouldProcess("$db on $server", "SMO drop")) { $server.databases[$dbname].Drop() $server.Refresh() [pscustomobject]@{ ComputerName = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.name Status = "Dropped" } } } catch { Write-Message -Level Verbose -Message "Could not drop database $db on $server" [pscustomobject]@{ ComputerName = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.name Status = (Get-ErrorMessage -Record $_) } } } } } } } |
