Fully automated report generation and email

Question

I am trying to get a report (from a query) to run automatically every Tuesday morning.
This is my job
BEGIN
     dbms_scheduler.create_job (
          job_name          => 'GEN_XLS_RPT_AND_EMAIL',
          job_type          => 'STORED_PROCEDURE',
          job_action          => 'gen_bomreport_proc',
          start_date          => to_timestamp('05-12-2009 07:00','DD/MM/YYYY HH24:MI'),
          repeat_interval     => 'FREQ=DAILY; BYDAY=TUE; BYHOUR=7',
          enabled               => true,
          comments          => 'Weekly CSV Reports Output at 7:00AM'
END;Then I have a procedure
PROCEDURE gen_bomreport_proc IS
DECLARE
    l_id number;
    l_document BLOB;
BEGIN
     l_document := APEX_UTIL.GET_PRINT_DOCUMENT (
          p_application_id          => 109,
          p_report_query_name          => 'qry_Report_1week',
          p_report_layout_name     => 'qry_Report_1week',
          p_report_layout_type     => 'application/excel',
          p_document_format          => 'xls'
     l_id := APEX_MAIL.SEND (
          p_to        => 'to@me',
          p_from      => 'from@you',
          p_subj      => 'Weekly Report',
          p_body      => 'Please review the attachment.',
          p_body_html => 'Please review the attachment'
   APEX_MAIL.ADD_ATTACHMENT (
       p_mail_id    => l_id,
       p_attachment => l_document,
       p_filename   => 'report_' || to_char(sysdate-8, 'YYYY') || '_' || to_char(sysdate-8, 'DD-MM') || '-' || to_char(sysdate-1, 'DD-MM') || '.csv',
       p_mime_type  => 'application/excel');
END;And the query that is supposed to get ran to generate the report saved as 'qry_Report_1week'
SELECT organization_name, quote_description, quote_name, quote_pwd, user_id, contact_last_name || ', ' || contact_first_name contact_name,
  email, create_date, qty, unit_price, ext_price, discount_percent, company_name, item_no, supplier_name, product_category, mfg_part_no,
  quote_id, customer_id, exalt_user_id
FROM bom_detail_cdw2
where create_date BETWEEN sysdate-8 and sysdate-1 order by create_date;I tried running the job
begin
DBMS_SCHEDULER.RUN_JOB (
   job_name => 'GEN_XLS_RPT_AND_EMAIL',
   use_current_session => false);
end;I read a lot about scheduler, APEX_UTIL.GET_PRINT_DOCUMENT and APEX_MAIL.ADD_ATTACHMENT, but I'm sure I missed something. Any help would be appreciated... Thanks

Answer 1

Thanks Vorlon, your link was a bit helpful.
Alright, I am making progress, but have had to come up with an alternative to the Report Query as found out that you need BI and we don't (and won't) have that.
Option 1: dump the query result in a csv file
Problem: I can't attach the csv to the email
CREATE OR REPLACE PROCEDURE gen_bomreport_proc
AS
     l_report  BLOB;
     f_report  UTL_FILE.file_type;
     bomdata_buf VARCHAR2(24000);
     bomdata_header VARCHAR2(512);
     l_id number;
     CURSOR bomdata_cur IS
          SELECT * FROM BOM_DETAIL_CDW2
          where create_date BETWEEN (sysdate-8) and (sysdate-2) order by create_date;
BEGIN
     -- Create and populate file
     f_report := UTL_FILE.fopen ('TESTDIR','bom_output.csv', 'W');
     bomdata_header := 'Organization,Description,Quote Name,Quote PWD,User ID,Email,Created,QTY,Unit Price,Ext Price'||
          ',Disc. %,Address,' || 'Item No,Mfg Part No,Contact Name,Supplier Name,Product Category,Quote ID,Customer ID,Exalt User Id' || chr(10);
     UTL_FILE.PUT_LINE(f_report, bomdata_header);
     FOR bomdata_rec IN bomdata_cur LOOP
          bomdata_buf := bomdata_rec.organization_name || ',' || REPLACE(bomdata_rec.quote_description,',','') || ','
          || bomdata_rec.quote_name || ',' || bomdata_rec.quote_pwd || ',' || bomdata_rec.user_id || ','
          || bomdata_rec.contact_first_name || ' ' || bomdata_rec.contact_last_name || ',' || bomdata_rec.email || ','
          || bomdata_rec.create_date || ',' || bomdata_rec.qty || ',' || bomdata_rec.unit_price || ',' || bomdata_rec.ext_price
          || ',' || bomdata_rec.discount_percent || ',' || bomdata_rec.company_name || ',' || bomdata_rec.item_no || ','
          || bomdata_rec.supplier_name || ',' || bomdata_rec.product_category || ',' || bomdata_rec.mfg_part_no || ','
          || bomdata_rec.quote_id || ',' || bomdata_rec.customer_id || ',' || bomdata_rec.exalt_user_id;
      UTL_FILE.PUT_LINE(f_report, bomdata_buf);
    END LOOP;
     -- Part where I convert UTL_FILE.file_type into a BLOB and store in l_report ?? --
     UTL_FILE.FCLOSE(f_report);
     -- End
     -- email part - I'm ok here
END;ok, so there's a line:      -- Part where I convert UTL_FILE.file_type into a BLOB and store in l_report ?? -- which I have searched for, to no avail
Option 2: dump the query result in a BLOB
Problem: I need to write strings/literals into the BLOB, but it keeps throwing the error PLS-00382: expression is of wrong type, when I write something like:
DECLARE
     l_report BLOB;
     bomdata_buf VARCHAR2(24000);
     bomdata_header VARCHAR2(24000);
BEGIN
     bomdata_header := 'Organization,Description,Quote Name,Quote PWD,User ID,Email,Created' || chr(10);
     l_report := bomdata_header;
END;
