Re: ORA-00904 on a valid view when using count(*)

follow-up on this one...
it seems that everything else won't work like select max(open) from gain_view
or select name from gain_view
or select max(length(security_name)) from gain_view... except for select * from gain_view...
tried these for almost all columns and am still getting 904 error...

btw, trade_quotes_vw is valid
