I have an sql question. I have a table that holds user information that includes their id and who they report to.
user ----- id (int) supervisor (int) This heirarchy goes several levels deep. Without changing the db structure, what is my easiest way to determine if user x is a supervisor for user y? User x may not be the immediate supervisor, but may be a supervisor or his supervisor, etc. I can do it with PHP by gettign the supervisor, then getting the supervisor's supervisor, etc, but this is slow. Any other ideas will be very much appreciated!
