Re: [GENERAL] Date & Time

now is a constant, while now() is a function. so, to me,
it should be always now unless you really need now().
what's more, in my impression, now() is not in any official
doc, it is like a rescue for now. however, in this case,
seems there is not much difference.-- oops


as for current_timestamp: I bet it is cos the sql92 thing.
now and now() is not sql92 standard. but not sure if now
or now() are the underlying thing, not sure even whether now
and now() are from the same code. Anybody ideas?
