Question

I have three tables:

Author(AID, Name) Title(TID, Name) AuthorOfTitle(ID, AID, TID) 

My question is how do can I see only Authors that are connected to no titles, that is Authors where there is no record in AuthorOfTitle. How to do this in SQL. Btw am using MS Access 2007.

Answer 1

This ought to do it:

SELECT A.* FROM Author A LEFT JOIN AuthorOfTitle T ON A.AID = T.AID WHERE T.ID IS NULL
