Tabular Form - Checkbox

Question

This is a simple requirement which I have for the first time. I want to have a checkbox in a
tabular form, which will show checked value for 'Y' and unchecked for NULL. This sounds
simple and is actually a usual requirement in many cases. However, I can't get it working
in this example:
http://htmldb.oracle.com/pls/otn/f?p=31517:123
1. Checking some of the rows and then trying to update the table is resulting in a no data
found error message,
2. Checking all the values will not result in an error,
it will update the other columns but it will not update
the checkbox column.
Can someone please explain how to handle something like that?
Thanks in advance,

Hello Denes,
" However, the hidden item is not a problem"Sorry about that. Didn't notice you changed it to editable field.
" … but G_F10 array "Yes. The G_F10 array will contains values only for the checked rows. So if you'll take row 5, which is not checked, the i index will be 5, but you don't necessarily have HTMLDB_APPLICATION.g_f10 (5) if you didn't check 5 rows.
If you want to act only on the checked rows, you need to loop on the (currently) G_F10 elements. You should attach the checkboxes to the empno column – HTMLDB_ITEM.CHECKBOX(1,empno) – and then use it as your key in the where clause.
I believe your report query should look something like this (and of course you need to show this column):
SELECT  HTMLDB_ITEM.checkbox (1,empno) " ", ename,
       HTMLDB_ITEM.select_list_from_query
                                     (3,
                                      job,
                                      'select distinct job, job from emp'
                                     ) job,
       HTMLDB_ITEM.popupkey_from_query (4,
                                        mgr,
                                        'select ename, empno from emp',
                                        10
                                       ) mgr,
       wwv_flow_item.date_popup (6, NULL, hiredate) hiredate,
       HTMLDB_ITEM.text (7, sal, 10) sal, HTMLDB_ITEM.text (8, comm, 10) comm,
       HTMLDB_ITEM.select_list_from_query
                                     (9,
                                      deptno,
                                      'select dname, deptno from dept'
                                     ) deptno,
       check_char check_char_value
  FROM emp_garbageand your update process, something like this:
BEGIN
   FOR i IN 1 .. HTMLDB_APPLICATION.g_f01.COUNT
   LOOP
      UPDATE emp_garbage
         SET job =
                  REPLACE (HTMLDB_APPLICATION.g_f03 (i), '%' || 'null%', NULL),
             mgr =
                  REPLACE (HTMLDB_APPLICATION.g_f04 (i), '%' || 'null%', NULL),
             hiredate = HTMLDB_APPLICATION.g_f06 (i),
             sal = HTMLDB_APPLICATION.g_f07 (i),
             comm = HTMLDB_APPLICATION.g_f08 (i),
             deptno =
                  REPLACE (HTMLDB_APPLICATION.g_f09 (i), '%' || 'null%', NULL),
             check_char = 'Y'
       WHERE empno = to_number(HTMLDB_APPLICATION.g_f01 (i));
   END LOOP;
   COMMIT;
END;Regards,
Arie.
