RE: Sql Skeleton Sample...

The easiest way, if you're not concerned about the values, is to use
COALESCE to replace the NULL with a value. THen you don't have to worry
about the indicator.

EXWC-SQL
DECLARE XXX CURSOR FOR
SELECT COALESCE(numeric_field_with_possible_null,0)
FROM table
WHERE whatever
ORDER BY whatever
END-EXEC

This basically says, if the numeric field is null make it zero. You don't
have to worry about declaring or testing null indicators. However, if you
want to know whether you got a null, then the code samples provided by
others will be required.

I was wondering, if someone would be willing to share an rpgsql program,
that is very robust...

I'm looking for the techniques, to be able to handle null values (not change
them) but at least let the rpg continue, plus how to handle the various
error codes, that might arise..

right now, I have null's in my data data types (lovals), and the sql, cann't
handle these... So I would like the program to at least keep functioning,
and then let me handle the nulls later when it comes to displaying them...

Thanks, tim
