Query – Percentage of Physical Memory SQL Server is Currently Using

Note: Unlike other queries I have share here at TheSQLReport, I am the author of this one.   Sharing because I could not find it in my Google Searches.  Tested this back to version SQL Server 2012.   Also please remember that physical_memory_in_use_kb may be a constantly changing number depending on how SQL Server  is configured & the activity of the operating system.
