Function Get-DbaExecutionPlan { <# .SYNOPSIS Gets execution plans and metadata .DESCRIPTION Gets execution plans and metadata. Can pipe to 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 ExcludeEmptyQueryPlan Exclude results with empty query plan .PARAMETER Force Returns a ton of raw information about the execution plans .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.
