Hallo,
I need a qualifier, which fetches data from the database where
fielda = empty and fieldb = empty.
I suppose this is very simple but I don't see it. What do I write
into the qualifier?
null won't work, NULL won't work, Bindings Array with new String()
won't work. Database is mysql, in case it does make a difference.
I think I did this before and no, in memory qualifying won't do, too
much data without this. I do need to fetch the data with this kind
of qualifier from the database directly.
Regards
Ute
