In this video, we explore Recursive Common Table Expressions (CTEs) in Databricks SQL — a powerful feature that allows you to solve hierarchical or iterative problems within a single SQL query.

We’ll start by discussing Apache Spark 4.0 and its new features, then move into Databricks Runtime 17.x compatibility. From there, we’ll break down the concept of recursive CTEs, understand how they work, and go through two practical examples:

Counting from 1 up to N.

Building and querying hierarchical data.

By the end of this tutorial, you’ll understand how recursive CTEs can simplify queries for hierarchical data structures such as org charts, folder trees, or bill-of-material scenarios in Databricks SQL.
