PostgreSQL - Recursive CTEs

Date: 2024-06-07

This article explains PostgreSQL's recursive Common Table Expressions (CTEs), a powerful SQL feature for querying hierarchical data. Recursive CTEs, referencing themselves, enable traversal of tree-like structures. The article uses an organizational hierarchy example to illustrate how a recursive CTE can list all employees. It also demonstrates generating sequences like the Fibonacci sequence using recursive CTEs. The article briefly covers setting up PostgreSQL using Docker.
