Really???? Wow. Could you point me to the documentation that states
that you will get a different set of data for your cursor if you don't
use an order by statement?
So which is it? Are we set based, or are we "set based, but sets are
different depending on whether they are in order and in a cursor."

thinking in records and files.
Hmmm. Would you care to discuss the example of "existance?" To me, an
empty set is different then a non-empty set. They even have words to
differentiate the two.

In retrospect, your arrogant and conceited persona couldn't be natural.
It must be cultivated.

least the foundations so you do not sound like a "flat-earther" looking
for a kludge.
Oh, well, it turns out I do have an education, and years ago I did read
the books in question. Eventually, I went on to work with real world
business people to solve real world business problems.
Real world is a lot more interesting then theory. Those danged peoples
come up with so MANY different permutations and desires!!!!!\
I am rusty, and I miss it. Theory is fun too, as is poking fun at
myself !!!!!
