Page item to hold SQLERRM

Question

I am trying to catch the SQLERRM in a text field when a process fails and have it displayed on the screen, instead of on an error page. The book shows how I can create a generic error page. Is there any way to do this. This is section of code that seems to have the problem. PLSQL doesn't like # and the item shows nothing right now during an error.
exception
when others then
begin
:P3_SQLERRM := ' '||SQLERRM;
:P3_FLAG := 20010;
end;

Hi User515008,
The following code works like a charm. It is in a PL/SQL process that is fired by a button. When :P1_SOME_NUMBER contains a zero, the error is displayed correctly in :P1_RESULT.
-- ===================================================
DECLARE
l_Some_Number Number ;
BEGIN
-- Do a bad thing.
l_Some_Number := 100 ;
l_Some_Number := l_Some_Number / :P1_SOME_NUMBER ;
:P1_RESULT := l_Some_Number ;
:P1_ERROR_MESSAGE := 'No bad thing.';
EXCEPTION
WHEN OTHERS THEN
:P1_ERROR_MESSAGE := 'We did bad.';
:P1_RESULT := SQLCODE || ' - ' || SQLERRM ;
END;
-- ===================================================
Have you checked :P3_SQLERRM in your configuration to make sure that it is not being reset to a default value? Check your session state and turn debugging on.
Hope this helps.
