How to apply sort on an already dispaled resultset from a procedure

Question

Hi,
I have a data block for which the 'query data source type' is PROCEDURE. When I query the block all the records in the procedure are displayed. Then I query for a specific value for the DATE column (ex: 27/07/2010) and it displays records for only 27/07/2010. Now I want to sort the displayed records.
My columns are DATE, TRANSACTION NUMBER, PROJECT CODE
I have a button each for DATE, TRANSACTION NUMBER, PROJECT CODE to do the sorting. When I click on the PROJECT CODE sort button , the already retireved records for 27/07/2010 must be sorted according to project code.
But this is not happening. The current coding will query the data block for all the records and then apply the sorting for DATE column.
Please advise.

Actually i don't know but what i gave u but i have read that If you attempt setting the where clause in the block it is totally ignored.
i hardly search just found the following...
Subject:  How to Filter Rows on Block Based on Stored Procedure in Oracle Forms? 
  Doc ID:  Note:1078147.6 Type:  PROBLEM 
  Last Revision Date:  22-JUN-2004 Status:  PUBLISHED 
Problem Description: 
==================== 
Whilst in ENTER QUERY mode you would like to specify a search criteria to 
restrict the results of your query.  The block on which this query resides
is based on a stored procedure. 
Problem Explanation: 
==================== 
If you attempt setting the where clause in the block it is totally ignored. 
This happens with both the 'Ref Cursor' or 'Table of Records' variable.    
Problem References: 
=================== 
[Search Words: filter ]
Solution Summary: 
=================
With Forms 5.0 and above, you can use the Tools--> Datablock Wizard menu 
in the Object Navigator to enter the datablock wizard in a re-enterant mode.
You can then specify the query criteria there. 
Alternatively, you can pass the query criteria from Forms to the stored 
procedure as an IN argument. You can then use the parameter with the 
select statement (in the procedure you have created using the 'Table of Records
or 'Ref Cursor').
Solution Description: 
===================== 
If the blocks were created using the Datablock Wizard with the
"stored procedure" radio button, you can always re-enter the datablock wizard
for that block by clicking on the Tools-->Datablock Wizard. If you go to the 
Query tab on the bottom of the tab page you will notice that it requests the 
name of the parameter. This is where you enter -
   :parameter.<parameter_name> 
This method relies on having a parameter in the form that passes the 
value, for example p_deptno, into the stored procedure. This is done in order
to get the corresponding records from the emp table for all employees who work
in that deptartment.
Additionally create a PRE-QUERY trigger and assign the value of the deptno you 
are passing through this parameter using the following:
   (:parameter.<parameter_name>:= :dept.deptno).
If the blocks were created manually, however, YOU CANNOT use the re-enterant 
option to go to the Datablock Wizard. For these type of blocks, use the method
suggested below.
METHOD FOR MANUALLY CREATED BLOCKS:
===================================
Re-enter the Datablock Wizard by using the Tools--> Datablock Wizard menu of the 
Object Navigator.  You will notice that you will not be able to see any 
procedure in the Datablock Wizard in re-enterant mode.
To use this method, you will need to include one more parameter to your query
procedure as an IN parameter. For example, if you are passing deptno as query
criteria, click on the "Query Data Source Arguments" of your block property 
sheet and include the following:
    ARGUMENT NAME: set to  P_DEPTNO or (any variable name)
    TYPE: set to the appropriate datatype, for example, NUMBER
    TYPENAME: set to dept.deptno%type, for example
    MODE: set to IN
    VALUE: set to :dept.deptno(the :blockname.itemname you are passing
                               as query criteria.).
In the query procedure, include this parameter as an IN argument, and as the 
2nd parameter.  For example:
    Procedure  empquery_refcur(emp_data IN OUT empcur, v_dno IN number) AS ....
Finally, include this paramter in your select statement of either 'Table of 
Records' or 'Ref Cursor' as
    select empno, ename
     from emp
      where deptno=nvl(v_dno, deptno);But no chance to Sort it may be from inside the procedure itself.
Hope this helps...
