I received the "cannot sort on field that does not exist" error
message a few times, selecting from views that relay on stored procs,
and I think that my case cannot be explained by that limit. When it
happened, the very next executing of the query gave the right results,
as it always did.

The tables involved do contains lots of little records, but the views
only see a minimum range at a time. There are no varchar fields, just
integer IDs and datetime timestamps.

Are there other situations for that error to occur?

thanks,
bye, lele
