Function Export-DbaExecutionPlan { <# .SYNOPSIS Exports execution plans to disk. .DESCRIPTION Exports execution plans to disk. Can pipe from Export-DbaExecutionPlan :D 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 Databases Return restore information for only specific databases. These are only the databases that currently exist on the server. .PARAMETER Exclude Return restore information for all but these specific databases .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 .NOTES Tags: Performance dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
