Feature request : support accumulations on output (compound assignments)

[Fleid]

The UPDATE and MERGE commands in SQL allow compound assignments:

+= Add and assign
-= Subtract and assign

I can't think of a way to do that with the current output binding.
Supporting these assignments would allow us to build accumulations (materialized views).

Drew, I suppose this is for others stumbling on this issue?

@Fleid - yep! adding just a bit more context as we get more traffic.
