...All they really need to do is make SUM() OVER work according to ANSI standards (or so I've heard). Of course, that particular documented feature change will break the hell out of a lot of folks code when they do. 😛 Not likely they'll wait for a couple of cycles and a deprecation notice for that one, either.
Actually, I think that MS may be OK on that. I just checked the (draft) standard and it looks like the ORDER BY is optional for the old aggregates, though I have not found a clear definition of what it should mean. My guess is that MS would implment it to act like today's if there is PARTITON BY but no ORDER BY, and otherwise do the running totals.

I believe it's the change in the way that PARTITION BY works that would break a lot of code.

Thing is, I can't find anywhere that SUM's behavior with PARTITION BY is defined unless ORDER BY is also defined. Since right now SUM con only be used with PARTITON BY and no ORDER BY, there should be no conflict. Unless I've missed something...?

I can thoroughly recommend Wilga Tree shiraz - (I think it was 2007) , I bought one on impulse - it was excellent! The local wine shop has now sold out. I'd never seen the brand before or since.

Heh.. Mainstreamers! 😛
You may never heard Lugana but it's definitely the best wine I know. 😉

What are the details of that required change?

I had a short stint working for the marketing manager of a hospitality retailer. He often got free samples of the various offerings of breweries, wine merchants, cider makers etc, which were shared with his staff. Free beer at work - O happy days. 😀
Pity I couldn't cycle to that job.

reminding me of college, there was a band named 'Free Beer' that was very popular, for some reason . . .

Working my way though college (and later) as a bartender/waiter, got to try lots of things I might not otherwise have done so.
Now I like to relax with a nice glass of Sambuca or B&B on occasion.

This is pretty genius. Talk about causing some problems for the bar trying to book them. I can see it now, in big bold letters "TONIGHT: FREE BEER"
