I know, but I would like to prefetch only just a few columns from the joined 
tables, not all of them.

Even if I would add to that arrayref some columns from the joined table, 
DBIC will get all the columns from those tables.

So, it is not possible to select only some specific columns from the joined 
tables?

Thanks.
