Question

Hey guys, first off all sorry, i can’t login using my yahoo provider.
anyways I have this problem. Let me explain it to you, and then I’ll show you a picture.

I have a access db table. It has ‘report id’, ‘recpient id’, and ‘recipient name’ and ‘report req’. What the table “means” is that do the user using that report still require it or can we decommission it.

Here is how the data looks like (blocked out company userids and usernames):
*check the link below, I cant post pictures cuz yahoo open id provider isnt working.

So basically I need to have 3 select queries:

1) Select all the reports where for each report, ALL the users have said no to ‘reportreq’. In plain English, i want a listing of all the reports that we have to decommission because no user wants it.

2) Select all the reports where the report is required, and the batchprintcopy is more then 0. This way we can see which report needs to be printed and save paper instead of printing all the reports.

3)A listing of all the reports where the reportreq field is empty. I think i can figure this one out myself.

This is using Access/VBA and the data will be exported to an excel spreadsheet. I just a simple query if it exists, OR an alogorithm to do it quickly. I just tried making a “matrix” and it took about 2 hours to populate.

Answer 1

1) This query works by taking each report ID and looking for a row where someone has not marked it as “not required” (with the assumption that ‘n’, and ‘N’ are the only ways to indicate that). If it finds any rows for that report ID that are still required.

SELECT DISTINCT report_id FROM table_name AS outer
  WHERE NOT EXISTS
    (SELECT report_id FROM table_name
    WHERE report_req NOT IN ("n","N")
      AND report_id=outer.report_id);

2) This query just adds up the values of batchprintcopy on a per-report_id basis (where the report is required, same assumption as above).

SELECT report_id, SUM(batchprintcopy) FROM table_name
  WHERE report_req NOT IN ("n","N")
    AND batchprintcopy > 0
  GROUP BY report_id;

3)

SELECT report_id FROM table_name
  WHERE report_req IS NULL OR report_req = "";
