Query to get Member Info

Hi,

I have a table which have the following columns

Id                       Member                                Access                                     BossName

Eg

Abc123            Peter                                      Admin                                        Dan

Abc123            John                                      User                                            Marc

Abc123           Derek                                      Admin                                        Abby

Abc123           Dan                                       User                                             null

I am trying to come up with the query to see who are the Member with Admin access in a spefic ID and for the members with Admin access if their BossName is part of the same ID as a user or not.

For eg in the above as you see there are 2 members who are the Admin Peter and Derek. and Peter Boss Dan is a user as well in the same ID.

So in this case the query should return below exception report 

Id : Abc123                       Member : Derek                             BossNAMe : Abby

Any suggestions.

Thanks-
