It appears that this form contains (at least) two block. Are they database or control blocks? If the former, you can change the status directly in a form (:room.room_status := 'booked'). If the later, you'll need the UPDATE statement with the appropriate WHERE clause.

What do you use a checkbox for? You enter ROOM_ID. ROOM_STATUS is changed from "available" to "booked". So, what does the checkbox do?

I have given checkbox value 'Available' and 'Booked'. I have used when_checkbox_changed trigger. when I will click to change checkbox, the :room.room_status will be changed to 'Booked' from 'available'. Its my thinking. But, how can I implement it? Or any other solutions?

So share your code with us!

Did you properly set checkbox item's checked and unchecked values (in item's Property Palette window)?

I have a column 'status' in room table. at first, All the room_id status set to available. I wanted to do, when I input a room_id in reservation table, the status of that room will be changed to booked in room table. for this, in reservation block i take a column 'status'. when-valid-item trigger applied, so that when i input a room_id, its status will be shown in reservation.status. I convert the status text item to checkbox. then used when-checkbox-changed trigger

--when-checkbox-changed
begin
if :reservation.(checkbox_name) = 'Booked' then
:room.status :='Booked';
else
:room.status := 'Available';
end if;
end;
It works, if I also convert the :room.status column to checkbox and number of item displayed = 1
Any Other solution please?
