I have 2 tables:
Orders
order_id   order_total
----------------------
1          150
2          230
Items
order_id   item_number
-----------------------
1          abc
1          foo
2          123
2          bar
2          test
I'd like to join both tables and concatenate the item_number column, so the results will looks like this:
order_id    order_total    item_number_concat
---------------------------------------------
1           150            abc, foo
2           230            123, bar, test
What's a way to do this in SQL Server 2008?
