This is a requirement, not a question! Which part of this are you having trouble with and what have you tried so far?

The absence of consumable DDL, sample data and desired results is, however, evidence of the absence of my response

I also have to ask "WHY"? Why do you need to "batch" this instead of just doing all 2 million rows, which most servers can easily handle?

And the reason why we ask such questions is because it will help us identify the best way possible to accomplish your task while, at the same time, possibly get you thinking that there might be a better way.

For example, a lot of people have started posts with "I need to iterate over the rows of a table...". In most cases, it turned out that the use of such RBAR was totally unnecessary and a set-based solution turned out to be far superior to what the OP thought was necessary.

--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.

Huh? I don't understand what you're saying. It doesn't seem to answer any of the questions asked.

Anyway, you might gain some insights into how to do "paging" in a select by reading this article:

However, this is no substitute for the insights you may be gaining by allowing us to help you with your particular problem. But to help you we need more information about your scenario than you have provided thus far.
