I'd recommend sending HaskellDB questions to the haskelldb users
mailing list. You do need to subscribe first. Now to your question:

Hi all, project (Server.name << s!Server.name # Vendor.name << v!Vendor.name # Model.name << m!Model.name # Server.system_id << s!Server.system_id)
This is by design. Just like in SQL, the column names are not disambiguated. If you wrote a SQL query like: select * from Server join Model on ... join Vendor on ... you would get duplicate column names. You must use unique column names in the projection. Check out the haskelldb-th package for Template Haskell utils for easily creating column names if you don't want to declare them by hand. Justin
