Thank you
A very interesting question.
Alas, I could see no other way to work out the answer, than to run the code.

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)

Thanks for a very interesting question.

Got it right by a wrong assumption :-)
Figured that Latin1_General_100_CI_AS will always be the "first" and prevailing collation (and hence picked the only option having "C" as the first character).
After answering, when running and playing with the code, I found that my assumption was wrong, because if the collations included e.g. Arabic_100_CI_AS, Czech_100_CI_AS or Danish_Greenlandic_100_CI_AS, the result(s) would have been different.

You may find the following pages helpful for digging deeper into the matter:
Collation Settings--check out the SQL LCID column (since noted in hex, any value lesser than 0x0409 will be listed before Latin1_General_100_CI_AS);
Collation Names--which will list the most recent collation names (with the _100 designator in the name) along with the older equivalents (as used on the previously mentioned page; unless the collation got introduced with SQL 2008).
Go
