Hi Guys:
Null <> CHR(0).
In fact NULL is totally imbecile. Here is a poem I wrote long time ago.
------------------------------------------
Ode to Null
It is neither a mountain nor a creek;
It is neither Latin nor Greek;
It is neither strong nor weak;
It is neither courageous nor meek.
It is neither nothing nor something;
It is neither a good thing nor a bad thing;
It is neither a big thing nor a small thing;
But it is something we have to deal with among all things.
It is neither a lender nor a borrower;
It is neither a zero nor a blank;
It is neither here nor there;
But, in programming, it is everywhere.
Oh! NULL, Oh! NULL!
You are neither a push nor a pull;
You always make us mull
Ov'r your dangerous effects, Oh! NULL!
