Rounding values for display

Question

Hi all hope you can help.
I have a numeric DB column say 566785.8975. The value of the information in the column cant be changed. The application performs two functions data input for the owners and view for the customers.
Idealy I want to only display to two decimal points for the customers
I have tried using the the ROUND command with no success using source as a PL/SQL expression or function and a value of ROUND(GROSS,2) where GROSS is the column name
any ideas?
Thanks

Hi Bjorn - the problem with the TO_CHARing (having suggested it in the first place - sorry) is if you want to use automated row processing to update the page.
However, you could have an item (your gross_read_only) which is not linked to a DB column, and then all your automated fetches and updates would work fine.
You can set the value of this item using a SELECT statement within the item source, or a computation when the page is rendered.
In either case, SELECT just the read_only item (TO_CHAR it as described), and I see no reason why it shouldn't work.
In other words - for the item source:
SELECT to_char( GROSS, '999G999G999G999G990D00') GROSS_READ_ONLY
FROM TABLE
where ID = :P1_ID_ITEM
or in a PL/SQL item computation:
declare
l_value VARCHAR2(4000);
begin
select to_char(GROSS, 'FML999G999G999G999G990D00') into l_value
FROM TABLE
where ID = :P1_ID_ITEM;
return l_value;
(or :P1_READ_ONLY_ITEM := l_value in a page computation)
end;
Does this help?
