Remove a user without leaving orphan data in SQL Server
Completely remove users from SQL Server without leaving orphan data
Context
Dropping a user from the logins section can create orphaned users on the databases, so it is advised for you to remove database access before then deleting the user.
This can be quite time consuming, so armed with the various information I found we came up with the code below.
It has saved me time when removing users, so hopefully it may help you.SQL
