SQL Server 2008 Express CONCAT() doesn't exist?

Question

I\'m making switch from MySQL to SQL Server 2008 Express and can\'t seem to find a CONCAT()-esque function. I have two columns I\'m trying to combine into a string and find

CONCATdoesn't exist in SQL Server 2008, it is new since SQL Server 2012.

You could use instead:

select id1, id2, id1 +  ", " + id2 as combo1
FROM db1
group by combo1
