"NULL IS NOT FALSE" is true because NULL is not a value therefor it is not FALSE, because FALSE is a value. "NULL IS TRUE" is false because NULL is not a value so it's not TRUE. You can't compare NULL with anything. All you can do is tell if it "IS NULL" or "IS NOT NULL". _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
