How to create a SQL Server function to “join” multiple rows from a subquery into a single delimited field? [duplicate]

Answer 1

I don't belive there's a way to do it within one query, but you can play tricks like this with a temporary variable:

declare @s varchar(max)
set @s = ''
select @s = @s + City + ',' from Locations

select @s

It's definitely less code than walking over a cursor, and probably more efficient.
