Update interactive report according to the filter of the user

Question

Hi all
i'm working with Apex version 4.2/
i have an interactive rport page as we know it allows the user to make filtering ans sorting
I want to do as follow :
i created an interactive report in table
CREATE TABLE EMP
  EMPNO     NUMBER(4)                           NOT NULL,
  ENAME     VARCHAR2(10 BYTE),
  JOB       VARCHAR2(9 BYTE),
  MGR       NUMBER(4),
  HIREDATE  DATE,
  SAL       NUMBER(7,2),
  COMM      NUMBER(7,2),
  DEPTNO    NUMBER(2))
ALTER TABLE EMP ADD (
  PRIMARY KEY
(EMPNO)now i've created a new region called update_all_region with two text field items.
p30_sal 
p30_deptno
and an update_all button .lets take a look at the scenario :
lets say that the user doing sort on the IRR lets say give all the employees where the sal >10000.
lets say that the report return 100 rows to the result , result per page : 50.
now i'm entering in the update_all_region text field item the values :
p30_sal : 90000
p30_deptno : 30 and pressing the update_all button .i want that all the rows which appears in the report (total = 100) will be update.
i've tried to do this :
begin
FOR i IN 1..APEX_APPLICATION.G_F02.COUNT
LOOP
update emp
  set salary =  :p30_salary ,
  deptno= :p30_deptno
where employee_id  = apex_application.g_f02(i);
END LOOP;
commit;
end;problem :
this update only updates the 50 rows in the current page that i'm in it. and not the all 100 .
question :
is this the correct way to do this update , form whatt i've understood , i can take the object filter as a variable , and use it in order to update the table.
please you advice
Thanks In Advanced

Either write a classic report and implement your own filters, and use those on your update function, or try to retrieve the where clause Apex uses in the IR.
