Friends,
I was reading through the Rules section of the online docs, and noticed the
following note: (* is just an abbreviation for all the attribute names of a
relation. It is expanded by the parser into the individual attributes, so
the rule system never sees it.)
Does this mean that count(*) may return less than the total number of
records if all the fields in a record are NULL?
If this is true, is there a better way to get a count of records?
Thanks,
Peter Darley
