Using SQL Query for page item source does not insert populated value

Question

Hi All,
Following are the attribute details of a certain page item on an edit form:
Display As: Text Field
Page Item Source Type: SQL Query
Source value Expression: SELECT a from tab where id = 'ABC'
Although the field appears populated on the screen, but the value is not inserted in the table.
Can anyone help on this?
Thanks in advance,
Annie

Annie:
One solution is to define a pl/sql function that given a date will return the 'run-date'. Something like create or replace function get_prod_date(p_date in date) return date is
retval date;
begin
select run_date into retval from tab_x where run_date=p_date;
return retval;
end;Change the Source Type for the page-item back to 'Database Column'
Set Source value or expression to the 'database column name'
Set 'Post calculation computation' to be
get_prod_date(:pxx_date)
