Hi Andy,

No problem.

No I didn't mean it to imply sorting, it just states explicitly what 
"streaming" means, i.e. not being *forced* to hold the entire result 
set in memory.

This was your wording wasn't it??? I just added some linkage words: 
"When requesting results in this form" replaced "In this form". The 
first sentence states "the client may request", so I was following the 
wording.

Really, I just wanted to tighten the definition of streaming up. 
Internally at Tucana, we often refer to streaming as streaming joins to 
and from disk, rather than across the wire. I thought it may help with 
some of Rob Shearer's concerns also.

Cheers,
Tom
