Combine rows / concatenate rows

Question

I\'m looking for an Access 2007 equivalent to SQL Server\'s COALESCE function.

In SQL Server you could do something like:

Person

<

I think Nz is what you're after, syntax is Nz(variant, [if null value]). Here's the documentation link: Nz Function

---Person--- 
John
Steve
Richard

DECLARE @PersonList nvarchar(1024)
SELECT @PersonList = Nz(@PersonList + ',','') + Person
FROM PersonTable

PRINT @PersonList
