I know that's a mostly unused corner case and > all, but... ;) They survive to the idea that text/date/... are "basic" types in SQL. Maybe I'm lucky... they could prefer java references with new/equals...;-) If I take your example about details of && vs AND semantics, while teaching "programming concepts" I'm not going to discuss the fact that && is shortcut by the evaluator, as this is very specific. I'm not planing my students to know what "i=++i+i++;" could mean. If I teach about "java/c/c++/java", this may be an issue. So it depends on the course goal. Well, I'm happy that so many people have ideas about what to teach and how to teach it;-) Have a nice day, -- Fabien Coelho - coelho@cri.ensmp.fr
