Sorry, but the subject line made me crazy!!!!!!!
NULL IS NOT A VALUE.....it is "unknown". It is NOT blank, spaces, zero, or anything else one would remotely consider a value. There are reams written about the quality of NULL; a decent library search should reveal articles from the various IEEE journals, Data Base Programming & Design, DBMS, etc. as well as virtually all the ORACLE books.
