function Export-DbaExecutionPlan { <# .SYNOPSIS Exports execution plans to disk. .DESCRIPTION Exports execution plans to disk. Can pipe from Get-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 target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .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 InputObject 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 Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Export-DbaExecutionPlan .EXAMPLE PS C:\> Export-DbaExecutionPlan -SqlInstance sqlserver2014a -Path C:\Temp Exports all execution plans for sqlserver2014a.
