What is Group by cube in SQL | CUBE Operation | Gate prep

In this short video, I explain the CUBE operation in SQL in a simple and intuitive way. You’ll learn how the GROUP BY CUBE clause works and how it helps generate all possible aggregations across multiple columns in a single query.

This is especially useful for data analysis, reporting, and OLAP operations, where you need subtotals and grand totals without writing multiple queries. I walk through a clear example to show how CUBE differs from ROLLUP and standard GROUP BY.

If you’re preparing for SQL interviews, data analytics roles, or database exams, this concept is essential to understand.

Topics covered in this short:

How GROUP BY CUBE works
Difference between CUBE and ROLLUP
SQL aggregation with multiple dimensions
Use cases of CUBE in data warehousing

Perfect for students learning advanced SQL, business intelligence, or database management systems.
