Delete orphaned SQL Users

I have a Microsoft SQL Server that had a database called SQLDATABASE. It also had a user called SQLUSER. The SQLDATABASE was deleted but not SQLUSER. SQLUSER only belonged to SQLDATABASE. I want to know all of the "Broken" users (e.g. SQLUSER) that is not part of a SQL database so that I can "clean house". I can go into every sql user and delete them by looking to see if they are attached but that seems very inefficient and something a script can help with. This is what I am asking.



The server has 200 SQL Databases but 250 SQL Users. I want to remove the extra 50 SQL Users as they aren't being used and there is no reason to have them.



I am trying to find a script to either let me find (and delete) these SQL Users or at least identify so I don't have to go into each of the SQL Users individually.

  • Do you mean the login SQLUSER was left behind? A login exists at the server level, a user exists inside a database. If you drop a database, a user can’t be left behind, but a login can.
