As a bit of a sidebar, the default sucks for performance. ROWS is faster than RANGE in the testing I've done in the past. It would have been nice if that was the default. 🙁

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Completely agree. RANGE is a weird default. I almost always find myself wanting rows.
