Lov related issue

Question

hi
i am using oracle developer 6i.i designed a general ledgre form and what i m trying is to use a LOV,which has four records and when i open form LOV should appear and, what value i select it autometically show relate record and when i cancel then it show all record from database.even then i query or direct execute lov should appear so that user can select value from lov to view related record.
In this regard i created a lov and wrote a code but it is not working.i used also set_block_property('gl',default_where,' ')
any one know how can i perform this and which trigger should i use.
thnx in advance

If I have understood your problem you want to achieve is like this:
you show your lov; if a value has selected then you must do a query using this value; otherwise you must do a query for all the records.
So, if these conditions are ok you can try this:
You can put this code into a button
DECLARE
VALUE BOOLEAN;
BOTTONE NUMBER;
number_record number;
default_condition varchar2(2000) := null;
BEGIN
VALUE := SHOW_LOV('YOUR_LOV');
/** You have not selected a value **/
IF NOT VALUE THEN
default_condition := null;
set_block_property('your_block',default_where,default_condition);
go_block('your_block');
execute_query;
else
/** you have selected a value **/
/** your parameter represents value choosen from your lov **/
default_condition := 'your_field = '||your_parameter;
set_block_property('your_block',default_where,default_condition);
go_block('your_block');
execute_query;
end if;
END;
Hope it helps you,
