Hi. I have a custome Banweb page that is supposed to export delimited data. the closest thing that i have gotten is for it to create a table through a cursor and use owa_util.mime_header('application/vnd.ms-excel') to export the data as an excel file. I'm having problems because it's not smart enough to recognize a grade of 9/70 as a grade and instead displays it as Sept. 1970. What is a better way of exporting true delimited files through a Banweb page? Thank you.
