hi,

i've been trying to figure out how to avoid dataset column-key clashes  
when the dataset is on a join.

e.g.

db[:message_infos].join(:identities, {:id=>:author_identity_id})

if both :message_infos and :identities tables have an :id column, the  
result has only a single :id column-key and values from one of the :id  
columns are lost

can i simply alias columns in joined tables ?

thanks

c
