How to delete a record from a form

Question

Hello!
I'm trying to delete a record from a table called PETS. The pet name is in a textbox from a data block called DELETE_PET.
So i wrote in the WHEN_BUTTON_PRESSED_TRIGGER of the Delete button:
select PETNAME into p_name from pets where PETNAME = :DELETE_PET.PETNAME;
DELETE from PETS where PETNAME = p_name;
clear_block(NO_VALIDATE);
alert_id := find_alert('PET_DELETED');
choice := Show_ALert(alert_id);
commit;
exception
when NO_DATA_FOUND then
     alert_id := find_alert('PET_NOT_FOUND');
     choice := Show_ALert(alert_id);
     clear_block(NO_VALIDATE);
rollback;
end;
And it's not working!!!!! :( :( :(
Any help would be greatly appreciated!
Thank you.

Hi ,
Write your trigger as....
begin
begin
   select PETNAME into p_name from pets where PETNAME = :DELETE_PET.PETNAME;
  exception
    when no_data_found
      then
        alert_id := find_alert('PET_NOT_FOUND');
        choice := Show_ALert(alert_id);
        clear_block(NO_VALIDATE);
        return;
end;
DELETE from PETS where PETNAME = p_name;
clear_block(NO_VALIDATE);
alert_id := find_alert('PET_DELETED');
choice := Show_ALert(alert_id);
commit;
end;Question: Does your select statement return a value 'as you expect'...????
Try to run your form in debug mode , and you may discover the deletion is not taking place.....
