Introduction
CUBE
Summary

## Instruction

Let’s get started. In principle, ROLLUP and CUBE are similar. The difference is that CUBE does not remove columns from the right to create grouping levels. Instead, it creates every possible grouping combination based on the columns inside its parentheses. Take a look:

SELECT
location,
gender,
risk,
AVG(age) AS avg_age

Syntax-wise, we only replaced ROLLUP with CUBE. Let’s see what result we’ll get.
