Function Uninstall-DbaSqlWatch { <# .SYNOPSIS Uninstalls SqlWatch. .DESCRIPTION Deletes all user objects, agent jobs, and historical data associated with SqlWatch. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database Specifies the database to install SqlWatch into. Defaults to master. .PARAMETER Confirm Prompts to confirm actions .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .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: SqlWatch Author: Ken K (github.com/koglerk) Website: https://sqlwatch.io Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Uninstall-DbaSqlWatch .EXAMPLE Uninstall-DbaSqlWatch -SqlInstance server1 Deletes all user objects, agent jobs, and historical data associated with SqlWatch from the master database. #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "Low")] param ( [Parameter(Mandatory, ValueFromPipeline)] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string]$Database = "master", [switch]$EnableException ) begin { # validate database parameter if (Test-Bound -Not -ParameterName 'DacfxPath') { $dacfxPath = "$script:PSModuleRoot\bin\smo\Microsoft.SqlServer.Dac.dll" } if ((Test-Path $dacfxPath) -eq $false) { Stop-Function -Message 'No usable version of Dac Fx found.' } else { try { Add-Type -Path $dacfxPath Write-Message -Level Verbose -Message "Dac Fx loaded." } catch { Stop-Function -Message 'No usable version of Dac Fx found.' -ErrorRecord $_ } } } process { if (Test-FunctionInterrupt) { return } foreach ($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 } # get SqlWatch objects $tables = Get-DbaDbTable -SqlInstance $server -Database $Database | Where-Object {$PSItem.Name -like "sql_perf_mon_*" -or $PSItem.Name -like "logger_*" } $views = Get-DbaDbView -SqlInstance $server -Database $Database | Where-Object {$PSItem.Name -like "vw_sql_perf_mon_*" } $sprocs = Get-DbaDbStoredProcedure -SqlInstance $server -Database $Database | Where-Object {$PSItem.Name -like "sp_sql_perf_mon_*" -or $PSItem.Name -like "usp_logger_*" } $agentJobs = Get-DbaAgentJob -SqlInstance $server | Where-Object { ($PSItem.Name -like "SqlWatch-*") -or ($PSItem.Name -like "DBA-PERF-*") } if ($PSCmdlet.ShouldProcess($server, "Removing SqlWatch SQL Agent jobs")) { try { Write-Message -Level Verbose -Message "Removing SQL Agent jobs from $server." $agentJobs | Remove-DbaAgentJob | Out-Null } catch { Stop-Function -Message "Could not remove all SqlWatch Agent Jobs on $server." -ErrorRecord $_ -Target $server -Continue } } if ($PSCmdlet.ShouldProcess($server, "Removing SqlWatch stored procedures")) { try { Write-Message -Level Verbose -Message "Removing SqlWatch stored procedures from $database on $server." $dropScript = "" $sprocs | ForEach-Object { $dropScript += "DROP PROCEDURE $($PSItem.Name);`n" } if ($dropScript) { Invoke-DbaQuery -SqlInstance $server -Database $Database -Query $dropScript } } catch { Stop-Function -Message "Could not remove all SqlWatch stored procedures from $database on $server." -ErrorRecord $_ -Target $server -Continue } } if ($PSCmdlet.ShouldProcess($server, "Removing SqlWatch views")) { try { Write-Message -Level Verbose -Message "Removing SqlWatch views from $database on $server." $dropScript = "" $views | ForEach-Object { $dropScript += "DROP VIEW $($PSItem.Name);`n" } if ($dropScript) { Invoke-DbaQuery -SqlInstance $server -Database $Database -Query $dropScript } } catch { Stop-Function -Message "Could not remove all SqlWatch views from $database on $server." -ErrorRecord $_ -Target $server -Continue } } if ($PSCmdlet.ShouldProcess($server, "Removing SqlWatch tables")) { try { Write-Message -Level Verbose -Message "Removing foreign keys from SqlWatch tables in $database on $server." if ($tables.ForeignKeys) { $tables.ForeignKeys | ForEach-Object { $PSItem.Drop() } } } catch { Stop-Function -Message "Could not remove all foreign keys from SqlWatch tables in $database on $server." -ErrorRecord $_ -Target $server -Continue } try { Write-Message -Level Verbose -Message "Removing SqlWatch tables from $database on $server." $dropScript = "" $tables | ForEach-Object { $dropScript += "DROP TABLE $($PSItem.Name);`n" } if ($dropScript) { Invoke-DbaQuery -SqlInstance $server -Database $Database -Query $dropScript } } catch { Stop-Function -Message "Could not remove all SqlWatch tables from $database on $server." -ErrorRecord $_ -Target $server -Continue } } if ($PSCmdlet.ShouldProcess($server, "Unpublishing DACPAC")) { try { Write-Message -Level Verbose -Message "Unpublishing SqlWatch DACPAC from $database on $server." $connectionString = $server | Select-Object -ExpandProperty ConnectionContext $dacServices = New-Object Microsoft.SqlServer.Dac.DacServices $connectionString $dacServices.Unregister($Database) } catch { Stop-Function -Message "Failed to unpublish SqlWatch DACPAC from $database on $server." -ErrorRecord $_ } } } } } |
