Insert a Value into a Text Field

Question

Hello,
I have a prbmel. I have a Text Field Item on my page. Now I want that it loads automatically, so before de header is loaded, a value out of a tabel in it. Therefore I created an PL/SLQ statement
declare
function get_current_id return number
is
ret number;
begin
for i in (select my_column idt from my_tabel)
loop
ret:= i.idt;
end loop;
return ret;
end;
begin
:P1_ID:=get_current_id;
end;
I know taht it is working becasue I have tested it in the SQL Command line but in the Page the Value isn't displyed. Can someone tell me why?

Hi
I think you are trying to populate ID value (primary key) with the last value of your table? Is that you are trying? If it's NUMBER column you better try to use MAX function..
Since you want default value for only one item, Edit item P1_ID -> go to Default value section
Select default type as SQL and put following SQL
SELECT MAX(my_column) FROM my_table;So on page load, P1_ID will get populated with MAX value of my_column from my_table
