ORACLE DEVELOPER 10G FORMS, LOV AND QUERYING THE FORM

Question

I have a form and I built an LOV on a particular field. The LOV returns the values, I select a value, it goes into the field, but what I want is to have the form retrieve all the information from the database and display (only) all the data. But when I put a value in the field from the LOV, nothing happens. i have tried to have the form go into "enter_query" mode, then select from the LOV, then end the "when button pressed" with "excute_query". But it will ask if i want to save, i say no, then it just displays the first record in the database. what am i doing wrong?
thank you,
Steven

Answer 1

here is my complete code on this button: when i press the button, it keeps asking me if i want to save it (if i say yes, it adds it to the table in the database, which i do not want). however, if i first select "enter query" from the menu bar, and then click on my button, everything works as expected.
set_item_property('SL_3_ITEMS_HEADER.SL_3_SHORT_TITLE',queryable,property_true);
--Set_Block_Property( 'SL_3_ITEMS_HEADER', DEFAULT_WHERE, 'parker.SL_3_SHORT_TITLE=:sl_3_short_title');
declare
     SL3 varchar2(12);
BEGIN
     go_item('SL_3_SHORT_TITLE');
list_values;
SL3 := :SL_3_ITEMS_HEADER.SL_3_SHORT_TITLE;
     if SL3 is not null then
          select SL_3_SHORT_TITLE into :SL_3_ITEMS_HEADER.SL_3_SHORT_TITLE
          FROM parker.SL_3_ITEMS_HEADER WHERE SL_3_short_title = SL3;
     ELSE
          message ('You need to specify an SL-3 to be able to search');
     end if;
     exception
          when no_data_found then
          message('An SL-3 with that name does not exist.');
          clear_form;
     end;
     execute_query;
