Sorry for the vague title but I really didn't know what title to give to this problem:

I have the following result set:

ID   Data   Culture
1    A      nl-NL
2    B      nl-NL
3    C      nl-NL
4    A      en-GB
5    B      en-GB
6    A      en
7    B      en
8    C      en
9    D      en
10   A      nl

I would like to mimic the ASP.Net way of resource selection, user Culture (nl-NL)

SELECT Data FROM Tbl WHERE Culture = 'nl-NL'

Or when there are no results for the specific culture, try the parent Culture (nl)

SELECT Data FROM Tbl WHERE Culture = 'nl'

Or when there are no results for the parent culture, try the default Culture (en)

SELECT Data FROM Tbl WHERE Culture = 'en'

How can I combine these SELECT-statements in one T-SQL statement?
I'm using LINQ so a LINQ expression would be even greater.

The OR-statement won't work, because I don't want a mix of cultures.
The ORDER BY-statement won't help, because it returns multiple records per culture.
