Function Test-SqlPath { <# .SYNOPSIS Tests if file or directory exists from the perspective of the SQL Server service account .DESCRIPTION Uses master.dbo.xp_fileexist to determine if a file or directory exists .PARAMETER SqlServer The SQL Server you want to run the test on. .PARAMETER Path The Path to tests. Can be a file or directory. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .NOTES Author: Chrissy LeMaire (@cl), netnerds.net Requires: Admin access to server (not SQL Services), Remoting must be enabled and accessible if $sqlserver is not local 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.
