I am trying to pull together some data for a report and need to concatenate the row values of one of the tables. Here is the basic table structure:

Reviews

 ReviewID  
 ReviewDate

Reviewers

 ReviewerID  
 ReviewID  
 UserID

Users

UserID  
FName  
LName

This is a M:M relationship. Each Review can have many Reviewers; each User can be associated with many Reviews.

Basically, all I want to see is Reviews.ReviewID, Reviews.ReviewDate, and a concatenated string of the FName's of all the associated Users for that Review (comma delimited).

Instead of:

ReviewID---ReviewDate---User  
1----------12/1/2009----Bob  
1----------12/1/2009----Joe  
1----------12/1/2009----Frank  
2----------12/9/2009----Sue  
2----------12/9/2009----Alice

Display this:

ReviewID---ReviewDate----Users  
1----------12/1/2009-----Bob, Joe, Frank  
2----------12/9/2009-----Sue, Alice

I have found this article describing some ways to do this, but most of these seem to only deal with one table, not multiple; unfortunately, my SQL-fu is not strong enough to adapt these to my circumstances. I am particularly interested in the example on that site which utilizes FOR XML PATH() as that looks the cleanest and most straight forward.

SELECT p1.CategoryId,
( SELECT ProductName + ', '
  FROM Northwind.dbo.Products p2
  WHERE p2.CategoryId = p1.CategoryId
  ORDER BY ProductName FOR XML PATH('')
) AS Products
FROM Northwind.dbo.Products p1
GROUP BY CategoryId;

Can anyone give me a hand with this? Any help would be greatly appreciated!
