I've been working with SQL for nearly 10 years and this is the best explanation i have ever come across of recursive CTEs. Great job!

Notes:- Recursive CTEs are declared using the WITH clause and are composed of two parts: the anchor member and the recursive member.

Here's the basic structure of a recursive CTE:-

WITH RECURSIVE cte_name (column1, column2, ...) AS (
-- Anchor member: Initial query to start the recursion
SELECT column1, column2, ...
FROM base_table
WHERE conditions

UNION ALL

-- Recursive member: Query that references the CTE itself
SELECT column1, column2, ...
FROM cte_name
JOIN other_table ON condition
WHERE conditions
)
-- Main query using the CTE
SELECT *
FROM cte_name;
