Hi,
My understanding is different so it can be a or b. Assume
that there are 10 records and this column can have null
values. If 9 records have null and one record has vale as
zero then the answer would be zero and if all of them have
null then the answer would be null. If no rows satifies the
criteria then it would be null.
