SQLQuokkaSQLQuokkaPayroll stores one row per employee per month worked in 2025, with pay_month from 1 to 12; months with no work have no row. For each employee, ignore their most recent month. For every other month they worked, compute the total salary for that month plus the two calendar months before it, treating months with no row as 0. Write an SQL query that returns id, pay_month and cumulative_salary. Order the results by id ascending, then pay_month descending.
