Using QUERY_FIND by date range EBS-R12

Question

   HI ,
I have developed a custom form for EBS R12, and i used the standard technique to develop it,
I also used the QUERY_FIND object group to display search form. using below code in the pre-query trigger of the block
BEGIN
   IF :parameter.g_query_find = 'TRUE'
   THEN
      COPY (:query_find.item,
            'my_block.item'
      :parameter.g_query_find := 'FALSE';
   END IF;
END;
and everything is working fine.
but now i need to search for a DATE item, and the search should be by Date From and Date  to.
I can't use the copy function to do the search for date range.
so i want to know the standard way that I should use to do such search.
I thought to used SET_BLOCK_PROPERTY and change the DEFAULT_WHERE
is this a standard way to do this search, or there is other way to do that.
Best Regards
Amir

Hi,
Try something like this:
SELECT       grad_stu_id
FROM       grad_fee_structure_hist
GROUP BY  grad_stu_id
HAVING       COUNT ( CASE
                  WHEN  DATE '2010-09-01'  BETWEEN  grad_eff_fee_date
                                           AND        grad_exp_fee_date
                THEN  1
            END
          )     > 0
AND       COUNT ( CASE
                  WHEN  DATE '2009-09-01'  BETWEEN  grad_eff_fee_date
                                           AND        grad_exp_fee_date
                THEN  1
            END
          )     = 0
;If a NULL grad_fee_exp_date means that the row is currently in force, then use something like
NVL ( grad_fee_exp_date
    , DATE '9999-12-31'
    )instead of the raw date.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data. Explain how you get those results from that data, giving specific examples.
Always say what version of Oracle you're using.

Changed date comparisons to BETWEEN.
