@fharper "if asking in the query for one specific month at a time and iteratively executing the query via a batch macro can provide efficient results."
I was really just looking for validation that this was the best approach, as that is exactly what I am trying to do. I was able to run a different year without issue, so there is just something unique going on that I can dig into on my own.
To optimize it, I'd be interested if anyone has an approach to write in DB without having to stream out (while running SQL to delete the portion that is being re-appended), but right now the performance is acceptable for what I am trying to accomplish.
Thanks for the input everyone!
