Re: INSERT non-static data to array?
My understanding is that LATERAL VIEW goes the other direction: takes an array and makes it into separate rows. I use that a lot. But I also need to go the other way sometimes: take a bunch of rows and squeeze them down into an array. Please correct me if I'm missing something.
