What have you tried so far? Have you had a look at PIVOT, or (what many prefer), using a Cross Tab?

What would you insert if there are multiple source rows with the same Id? For example

id value

2 20

2 30

Would this require two inserts of 20 and 30, or a single insert of 50 (SUM), 25 (AVG), 20 (MIN) ... or some other aggregate?

If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
