Execute Query on form opening

Question

Hi,
I am developing an application....in that application I have two forms...one is Form A and the other one is Form B ...
Scenario Is ...Form A has a detail block with the fields like VOUCHERNO, DATE, AMOUNT. I want user to double click on FORM A'S detail block and it should pick that VOUCHERNO (read in global variable ..ive done this already) ...and on FORM 'B' which is a voucher maintenance form...contains that VOUCHER'S MASTER BLOCK and VOUCHER DETAIL BLOCK...fill that voucher no from global variable and automatically EXECUTE QUERY to bring the details of that voucher in form b's detail block.
My problem is that on NEW FORM INSTANCE of form B ive checked the record status its 'NEW' ..whenever I move the global variable value in voucher no for Form B to execute query it says WANT TO SAVE CHANGES ? YES NO CANCEL...even though I've used clear_form(no_validate)...ive used ENTER_QUERY also...but the problem is remain the same...please help and tell me how to do this. Thanks

Answer 1

create a PRE QUERY in Form B. There you use the global-variable
use the query-technique of my one-time-timer http://talk2gerd.blogspot.com/2007/01/one-time-timer.html
PRE QUERY:
BEGIN
  IF :global.nameOFglobal IS NOT NULL THEN
    :EMP.ENAME := :global.nameOFglobal;
  END IF;
END;try it
