How to put the SQL-statement returned value into the field (as a default)

Question

Hi,
I am using Developer/2000 (Forms Designer) under windows 98.
Please tell me how to put the SQL-statement value (as a default value) into the field before enter-query mode. Noted that I have tried the following ways but still some problems:-
1) Place the SQL-statement into PRE_QUERY trigger in the form/block level.
There is a message box which ask 'Do you want to save the changes?'.
2) Place the SQL-statement before execute enter_query. There is still a
message box which ask 'Do you want to save the changes?'.
Any hints? Thanks. Urgent.

Answer 1

solved it!
1) Suppress DEFAULT save message
if form_failure then
raise form_trigger_failure;
end if;
2) Place the default value before enter-query.
Ref: Title='Default value in query field in ENTER_QUERY mode' in designer forum by CVZ
form level trigger
============
WHEN-NEW-ITEM-INSTANCE
=======================
if :system.mode = 'ENTER-QUERY' then
:block.item := 'default waarde';
end if;
3) Suppress the changes whenever leaving the default field.
if :block.item is null then
-- assign statement
end if;
