I’m surprised HASH_AGG can do that! Didn’t know it was possible.

ENCRYPT definitely doesn't support windowing, just saying.

Wait, does EXTRACT really support windowing? I thought it didn't.

I thought HASH_AGG was more about aggregation without windowing, but I could be mixing it up with something else.

I feel like EXTRACT might not support windowing, but I can't recall the details clearly.

I remember practicing a question where we had to identify window functions, and LISTAGG was definitely one of them.

I'm a bit confused on the difference between some of these functions. I'll have to make an educated guess.

Wait, is LISTAGG a function that lets you group things together and then put them in a list? That sounds pretty useful for windowing!

ENCRYPT and EXTRACT are not functions that support windowing. They have different purposes in SQL.

HASH_AGG and LISTAGG are both functions that support windowing. They can help with aggregating and grouping data in a window.

Yes, LISTAGG is a function that concatenates the values of a column into a single string using a specified delimiter. It can be very useful for windowing functions.

EXTRACT is an interesting choice, but I don't think it's related to windowing either. It's more for extracting parts of a date or time value.

Hmm, ENCRYPT doesn't seem to have anything to do with windowing. That's just for encrypting data, right? I'd rule that one out.

HASH_AGG seems like a good option too, since it's an aggregate function that can be used with window functions. But I'm pretty sure LISTAGG is the right answer.

I think LISTAGG is the correct answer here. It's a function that allows you to concatenate multiple rows into a single string, which is a common use case for windowing.
