Too Long; Didn't Read

This post is the first in a series of articles about window functions in MySQL. We will use the 'window-function-demo' tool to show how to use the syntax and use examples of different window functions. Window functions are built-in MySQL functions that offer aggregate-like functionality on a defined range of rows in a query. The data we use represents a fictional competition where players earn points during each match. The information we use shows the total number of points a player has accumulated. The table has just four columns: an id that is the primary key, the name of the player, the number of. points scored by the player and the group.
