Tutorial: SQL Analytic Functions

SQL analytic ("window") functions compute a value for each row of input based on other rows, collectively known as a "window". The window is defined using OVER and can be refined using PARTITION BY, ORDER BY, and ROWS/RANGE BETWEEN. The value can be from a numbering function, navigational function, or an aggregate analytic function. To learn more, check out my Youtube video. For a text reference, BigQuery's article " Analytic function concepts in Standard SQL " is a great resource. Below, you can find the text referenced in the Youtube video, as well as some bonus content not in the video.

I'll just keep repeating this simple task to try out new techniques and observe how my performance changes.
