Interesting... When I run the example on my SQL Server (Denali, CTP 3) the result is: A,D,B,E,C

That's startling. I don't have a modern (windows 7 or later) platform available to test on, but given that all the locales ids are different there should be no imaginable way for a new locale version to affect the order of these collations; the only thing I can thionk of is that some locale ids have been changed.

It would be useful if you could run the following code and post the results here, so that we can see what has happened in Denali to make this order change.

select cname CollationName, collationproperty(cname,'LCID') LCID
from (values('bosnian_latin_100_ci_as'),
('corsican_100_ci_as'),
('latin1_general_100_ci_as'),
('norwegian_100_ci_as'),
('romansh_100_ci_as')
) X(cname)

I've run the same thing on Denali CTP3 and it returns the same results as sql 2008 R2.

Great question and great explanation. I can see how this could cause unexpected behavior. I definitely learned something today.

Thanks for the good news, Remi; I was quite wondering what on earth could be going on, and it's nice to know that it was nothing.

This all sounds like yet another reason to never use SQL_VARIANT columns in your database.

Great question. Not what I would have expected....but then, many aspects of SQLVariants are not what I would expect.

Agreed, it's like opening Pandora's Box. I'm not even sure what led Tom to finding this nugget, nevermind how I'd go about finding the full answer if he hadn't spoon-fed me what was going on in a reasonable amount of time.

Variant can burn from everything I've been seeing on the complexity of its rulesets.
