How can the PARTITION keyword be used in MySQL to achieve similar functionality to Window Functions?

Window functions are not directly supported in MySQL, but the PARTITION keyword can be used to achieve similar functionality. By using the PARTITION keyword in conjunction with aggregate functions like SUM(), COUNT(), or ROW_NUMBER(), you can group rows based on a specific column and perform calculations within each group. This allows you to calculate running totals, rankings, and other window function-like operations in MySQL.

SELECT
    id,
    name,
    score,
    SUM(score) OVER (PARTITION BY id) AS total_score
FROM
    players;
