Forms 4.5 Query Question

I'm using Forms 4.5 to query a document database with 7 tables. In order to be able to query all the fields, I created a view which joins all the tables. The queries themselves are fast, but since several of the detail tables have a lot (> 100) detail records, it retrieves a lot of rows. To view the records with all their repeats, I create a temp table with just the docno (key field) and call another form which contains blocks for all the tables, using the following procedure:
PROCEDURE temptable IS
current_docno varchar2(15); previous_docno varchar2(15); counter number;
BEGIN
delete from temptable;
current_docno := :docno;
LOOP
If current_docno <> Previous_docno THEN
insert into temptable (DOCNO) values (:docno);
counter := counter + 1;
END IF;
exit when :system.last_record = 'TRUE';
previous_docno := current_docno;
next_record;
current_docno := :docno;
END LOOP; open_FORM('C:\ORAWIN\A_FORMS\Test1.FMX',activate);
END; This takes forever, even if the end result is only 100 records or so, and then it takes a few minutes when I return to the query screen to start a new query.
My questions are:
- Is there a way to query all 7 blocks, and getting rid of the two forms?
- If not, is there a way to speed up my procedure above?
Sorry for the long post.
Thanks,
