Hi. New to Forms. Using 9i dev suite.
I want to have a control block on a form where a user say department _id and then run a query to populate the data block using the id
entered from the control block. The data in the
data block is query only, the user will make a selection from the
returned data to do something else
How do I make the control block entry populate the data block?
Thanks,
|

Hi,
Thank you so much.
I have tried different things and now i am confused.
Do you mean I have to have for example Set_Block_Property('DEPARTMENTS',DEFAULT_WHERE,'control.DEPARTMENT_ID');
but where should i put it?
i have created button called "query" when_button_press fires i have this coding inside this trigger
BEGIN
go_block('control');
Set_Block_Property('DEPARTMENTS',DEFAULT_WHERE,'control.DEPARTMENT_ID');
enter_query;
:DEPARTMENTS.DEPARTMENT_ID := :control.DEPARTMENT_ID;
EXECUTE_QUERY;
END;
but it cant work.what should i do?
thanks

Hi Dear Littlefoot
Thank you so much.If I can not code the ENTER QUERY mode, what should I do in below case? If I make DO_KEY ('ENTER_QUERY') as comment, it wont retrive any data from database block.
Thank you so much in advance.
This is ma PL/SQL code when press the button Query
DECLARE
Messg_Txt varchar2(100);
BEGIN
IF :SYSTEM.MODE = 'NORMAL' THEN
Set_Butt_Property.Enabled_False('delete_button');
Set_Butt_Property.Enabled_False('save_button');
Clear_Form(No_validate);
Value_Reassign(:Dis_Curtime, :Dis_Lname,:Dis_Fname,:Dis_Sysdate);
Set_Op_Mode.Set_Query (:form_mode);
go_item('CONTROL_BLOCK.FEECD_1');
DO_KEY ('ENTER_QUERY');
else
Set_Block_Property('CF92CAFEEGL', DEFAULT_WHERE,'FEECD = '''||:CONTROL_BLOCK.FEECD_1||'');
go_block('CF92CAFEEGL');
DO_KEY('EXECUTE_QUERY');
IF :SYSTEM.MODE = 'NORMAL' THEN
Set_Op_mode.Set_Query(:form_mode);
-- icba_msg(FALSE,'190323',1);
Op_Mode.Insert_Mode := FALSE;
IF Security_Setup.Delete_Allow = 'y' THEN
Set_Butt_Property.Enabled_True('delete_button');
END IF;
END IF;
END IF;
END;

Please, read the OraFAQ Forum Guide to learn how to properly format your messages.
As of your problem: try to make it simple and work, and later we'll make it fancy. In other words: remove ALL code that isn't necessary. Comment it all, except the part that looks exactly as the one I've written.
There are several apostrophes in your code which I don't have, so - why did you use them? What is the name of your control block? In the first post, you called it 'control', now it is 'control_block'.
You do not have to be in an ENTER QUERY mode to execute a query; imagine you've just entered a form and pressed 'EXECUTE QUERY' button - you'll get all records by default.
