Hi Guys:


  Null <> CHR(0).

  In fact NULL is totally imbecile.  Here is a poem I wrote long time


------------------------------------------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!

This works perfectly fine for me in 10.2


select OWNER, TABLE_NAME from dba_TABLES where owner >= CHR(0)

On the other hand "null" is undefined.  It's not CHR(0).

What component in DB I have to install to use  ">= CHR(0)" instead of
