Sorting

Hi, I'm having a bit of trouble... I have a simple report that lists employees birthdays. The report uses .. "where month(date_of_birth)=month" How can I sort this report by month (or can't it be done?) I have the Informix manuals and some 3rd party books but can't seem to get it!! I thought it would be (or would like it to be) something simple as ...order by month(date_of_birth) Can anyone point me in the right direction? Thanks, Joe
