How to write the code to insert into attendance table

Question

Hi,
I have a report
class lov (through which all the classes will be selected).
once any class seleted from the list it will display all the students in the class
my query in the report was
SELECT FIRST_NAME || ' ' || SURNAME "Pupil_Name",
er.pupil_number,
APEX_ITEM.CHECKBOX(1,er.pupil_number) "tickthebox"
FROM PEAS_PUPIL pu, PEAS_ENROLMENT_REGISTER er
WHERE pu.pupil_number = er.pupil_number
AND er.class_id = :P53_CLASS
pupil number column hidden becuase its a pk.
as pupil_name and checkbox (called tickthebox)
now I HAVE written on submit process to insert records into attendance table see below
for i in 1..apex_application.g_f01.count loop --- check is the selector checbox, pupil_number is the hidden column with the table's PK
INSERT INTO PEAS_ATTENDANCE (ATTENDANCE_ID,PUPIL_NUMBER) VALUES
attendance_seq.NEXTVAL,
APEX_APPLICATION.G_F01(i)
end loop;
but this is only inserting checked records ...not inserting unchecked records.
is there anyway i can insert both checked and unchecked records into tABLE.
THANKS

What I mean is that if you want to use checkbox item you must compare its value to current row ID.
You have two items containing pupil_number:
- APEX_ITEM.CHECKBOX(1,er.pupil_number)
- APEX_ITEM.HIDDEN(2,er.pupil_number)
When you call first one like "FOR i in 1 .. apex_application.g_f01.COUNT", you will get only pupil_numbers of checked checkboxes.
When you call second one like "FOR i in 1 .. apex_application.g_f02.COUNT", you will get pupil_numbers of all rows.
You get "no data error" because you reffer in your process to variable apex_application.g_f01(i) for row i, that is not checked.
That's why you should check in your process if current row is checked every time when you want to reffer to this checkbox. You can do it using this code:
FOR i in 1 .. apex_application.g_f02.COUNT
LOOP
FOR j in 1 .. apex_application.g_f01.COUNT
LOOP
IF apex_application.g_f01(j) = apex_application.g_f02(i) THEN
      /Your process for checked records/
END IF;
END LOOP;
      /Your process for unchecked records/
END LOOP;And I think you should modify your report query for:
SELECT FIRST_NAME || ' ' || SURNAME "Pupil_Name",
APEX_ITEM.HIDDEN(2,er.pupil_number)||APEX_ITEM.CHECKBOX(1,er.pupil_number) "tickthebox"
FROM PEAS_PUPIL pu, PEAS_ENROLMENT_REGISTER er
WHERE pu.pupil_number = er.pupil_number
AND er.class_id = :P55_CLASSYou can find some interesting information about using checkbox in APEX help.
