Do you also believe in square circles? This is a matter of definition.
I can post Dr. Codd's 12 rules if you have never read them.

That will give you random results, based on the internal state of the
database at the time of the query.
>> Well, you could write code to tell the engine to return exactly one row back, whether it is null or not. <<
I probably can, but that defeats the whole idea of a set-oriented
language. You wanted a set; an empty set is a set. You are still
thinking in records and files.
>> Celko, you might read a book on fundamental human communications. You
have missed the most important concepts. <<
Please, please, I have worked for years on my "abrassive Zen Master"
Newsgorup persona. Everyone that takes a live class from me is
surprised that I go one-on-one for hours or days after the class until
someone understands things. My attitude is that you should not use a
Newsgroup in place of an education -- actually read Codd, Date,
Dijkstra, et al before you post. Not the high level stuff, but at
least the foundations so you do not sound like a "flat-earther" looking
for a kludge.
>> Perhaps though I am missing your point celko. If so, could you be more precise? <<
Get a copy of DATA & DATABASES for the philosophy of RDBMS,
grasshopper. Come back and I will beat you with a stick some more!
