#ValidationTags#Messaging# function Export-DbaExecutionPlan { <# .SYNOPSIS Exports execution plans to disk. .DESCRIPTION Exports execution plans to disk. Can pipe from Export-DbaExecutionPlan Thanks to https://www.simple-talk.com/sql/t-sql-programming/dmvs-for-query-plan-metadata/ and http://www.scarydba.com/2017/02/13/export-plans-cache-sqlplan-file/ for the idea and query. .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER SqlCredential Credential object used to connect to the SQL Server as a different user .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 SinceCreation Datetime object used to narrow the results to a date .PARAMETER SinceLastExecution Datetime object used to narrow the results to a date .PARAMETER Path The directory where all of the sqlxml files will be exported .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 PipedObject Internal parameter .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: Performance, ExecutionPlan dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Export-DbaExecutionPlan .EXAMPLE Export-DbaExecutionPlan -SqlInstance sqlserver2014a Exports all execution plans for sqlserver2014a. .EXAMPLE Export-DbaExecutionPlan -SqlInstance sqlserver2014a -Database db1, db2 -SinceLastExecution '7/1/2016 10:47:00' Exports all execution plans for databases db1 and db2 on sqlserver2014a since July 1, 2016 at 10:47 AM. #> [cmdletbinding(SupportsShouldProcess = $true, DefaultParameterSetName = "Default")] param ( [parameter(ParameterSetName = 'NotPiped', Mandatory)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [parameter(ParameterSetName = 'NotPiped')] [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [parameter(ParameterSetName = 'Piped', Mandatory)] [parameter(ParameterSetName = 'NotPiped', Mandatory)] [string]$Path, [parameter(ParameterSetName = 'NotPiped')] [datetime]$SinceCreation, [parameter(ParameterSetName = 'NotPiped')] [datetime]$SinceLastExecution, [Parameter(ParameterSetName = 'Piped', Mandatory, ValueFromPipeline)] [object[]]$PipedObject, [Alias('Silent')] [switch]$EnableException ) begin { if ($SinceCreation -ne $null) { $SinceCreation = $SinceCreation.ToString("yyyy-MM-dd HH:mm:ss") } if ($SinceLastExecution -ne $null) { $SinceLastExecution = $SinceLastExecution.ToString("yyyy-MM-dd HH:mm:ss") } function Export-Plan { param( [object]$object ) $instanceName = $object.SqlInstance $dbName = $object.DatabaseName $queryPosition = $object.QueryPosition $sqlHandle = "0x";
