CSV file generation with timestamp time details

Question

CREATE OR REPLACE PROCEDURE extract_proc AS
l_rows number;
begin
l_rows := extract_function('select *
from table1 where date1 between trunc(sysdate) and sysdate
'MYDIR1',
'test.csv');
end;
I have a procedure extract_proc shown above which create a CSV in the directory MYDIR1 in the unix.
I would like to have the timestamp ie ddmmyyyyHH24:MI details in the CSV file name created. ie. to have a file name of test22072011.csv whenever it generates with respective timestamp to be prefixed or suffixed to the file number. Is ther any way to achieve this
Pls suggest
Many thanks

Why don't you set your file name dynamically? Something like:
AS
     file_name     VARCHAR2(50);
BEGIN
     file_name := 'test' || TO_CHAR(SYSDATE,'YYYYMMDDHH24MISS') || '.csv';
     extract_function(...,file_name);
END;
