Hi, 

I have a SQL problem for you all. What SQL qurey would I have to make
on the following table to extract the chain (thread) of emails in a
conversation.


         id|emailid|referenceid
         -----------------------
          1|  e125 |   Null             (Start of chain)
          2|  r1fe |   e125             (2nd letter in chain)
          ...
          ...
          n|  e4ju |   r1fe             (3rd in chain)

ie
a sucessulf qurey would return rows 1,2 & n because they are all in
the chain.

Hope you can help me with my problem,
