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 Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential 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 Databases The database name to remove or an array of database names eg $Databases = 'DB1','DB2','DB3' .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Tags: Delete dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire .LINK https://dbatools.io/Remove-DbaDatabase .EXAMPLE Remove-DbaDatabase -SqlInstance sql2016 -Databases containeddb Prompts then removes the database containeddb on SQL Server sql2016 .EXAMPLE Remove-DbaDatabase -SqlInstance sql2016 -Databases containeddb, mydb Prompts then removes the databases containeddb and mydb on SQL Server sql2016 .EXAMPLE Remove-DbaDatabase -SqlInstance sql2016 -Databases containeddb -Confirm:$false Does not prompt and swiftly removes containeddb on SQL Server sql2016 #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'Low')] Param ( [parameter(Mandatory = $true, ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer")] [object[]]$SqlInstance, [parameter(Mandatory = $false)] [object]$SqlCredential, [switch]$Silent ) DynamicParam { if ($SqlInstance) { return Get-ParamSqlDatabases -SqlServer $SqlInstance[0] -SqlCredential $SqlCredential } } BEGIN { $databases = $psboundparameters.Databases if (-not $databases) { Stop-Function -Message "You must select one or more databases to drop" } } PROCESS { if (Test-FunctionInterrupt) { return } foreach ($instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlServer -SqlServer $instance -SqlCredential $sqlcredential } catch { Stop-Function -Message "Failed to connect to: $instance" -Continue } $databases = $server.Databases | Where-Object { $_.Name -in $databases } foreach ($db in $databases) { try { if ($Pscmdlet.ShouldProcess("$db on $server", "KillDatabase")) { $server.KillDatabase($db.name) $server.Refresh() [pscustomobject]@{ ComputerName = $server.NetName 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.ConnectionContext.ExecuteNonQuery("alter database $db set single_user with rollback immediate; drop database $db") [pscustomobject]@{ ComputerName = $server.NetName 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.NetName 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.NetName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.name Status = $_ } } } } } } } } |
