Mercy on me...

Question

Hi, I am not an experienced Oracle DBA, only a user through other applications that I administer (content management/web apps). As it turned out, my employer has asked me to develop a PL/SQL tool to export table data to the back end, on a scheduled basis. I researched the matter and found more options than I can understand, even purchased some books and spent unimaginable amounts of time trying to set up APEX and such. In the end, I found several potentially viable scripts, many of them freely available over the internet, but they don't quite cut it: all the UTL_FILE scripts that I found export a csv file, but when a new one comes, it overwrites the old one. I need to be able to rename the existing one, with a date stamp, on a scheduled basis. All this needs to work in Solaris with Oracle 9i. That's what's caused me more trouble than anything. It gets worse, i then have to develop a front end reporting tool, a web interface to give the admin the ability to search for records from just two columns, by date range. I can't really use apex, or anything like that, it needs to be a general purpose, j2ee app that should work on any app server...
I have two days to come up with something that can be deployed, any help that you can provide is greatly appreciated it...
Lost.

Hello,
What have you done so far in utl_file? Do you have procedure opening , writing files but without date and time extension? Here is sample procedure, that can be used to generate a file_name with date and time and you can embed in your package and call it when you opening a file using UTL_FILE. Hope this helps you out.
-- Global variables to support following procedure. This procedure can open a monthly or daily file name, you can extend and time stamp i
g_file_date           DATE;                --Date current file was created
g_file_rotation       VARCHAR2 (20)  := 'DAILY';
g_file_number         NUMBER (3)     := 0;
g_file_name           VARCHAR2 (50);
  PROCEDURE make_file_name
   IS
      v_date_string   VARCHAR2 (10);
   BEGIN
      IF g_file_rotation = 'MONTHLY'
      THEN
         v_date_string := TO_CHAR (g_file_date, 'yyyymm');
      ELSE
         v_date_string := TO_CHAR (g_file_date, 'yyyymmdd');
      END IF;
      IF g_file_number = 0
      THEN
         g_file_name := g_module || '_' || v_date_string || '.log';
      ELSE
         g_file_name :=
            g_module || '_' || v_date_string || '_' || g_file_number
            || '.log';
      END IF;
   END make_file_name;Regards
