csv export...?

Google is not my friend today... I have a reportng tool on a database i have, and I want to be able to exort the selected results (I've saved the SQL query as a session variable for ease of use) and save that data as a csv file... with headers if possible... Now I have found loadsa sites that let me upload a csv file, but not the other way around... Anyone care to help? ********************************************************************* The information contained in this e-mail message is intended only for the personal and confidential use of the recipient(s) named above.
