Recursive CTE MySQL — Examples & 2025 Guide
Recursive Common Table Expressions (CTEs) are a vital feature in MySQL for solving hierarchical and tree-structured data problems—think org charts, folder structures, or bill-of-materials. With recursion, you can elegantly traverse parent-child relationships directly in SQL. However, authoring recursive CTEs remains a stumbling block for many analysts and developers, due to the tricky syntax and edge-case handling.
AI2sql eliminates that complexity: just describe your recursive query in natural language, and it instantly creates error-free, production-ready recursive CTE SQL for MySQL. No coding required. Instant results.
Understanding Recursive CTEs in MySQL
A Recursive CTE lets you reference itself within its definition. Common use cases include:
-
Traversing employee hierarchies
-
Unfolding folder trees
-
Aggregating paths (breadcrumbs) in navigation
Here’s the basic structure:
WITH RECURSIVE cte_name AS (<br> -- anchor member<br> SELECT ...<br> UNION ALL<br> -- recursive member<br> SELECT ... FROM cte_name ...<br>)<br>Real-World Examples: Recursive CTEs in Action
1. Employee Hierarchy
WITH RECURSIVE employee_cte AS (<br> SELECT id, name, manager_id<br> FROM employees<br> WHERE manager_id IS NULL -- Top-level manager<br> UNION ALL<br> SELECT e.id, e.name, e.manager_id<br> FROM employees e<br> INNER JOIN employee_cte c ON e.manager_id = c.id<br>)<br>2. Folder Structure Traversal
WITH RECURSIVE folder_tree AS (<br> SELECT id, folder_name, parent_id<br> FROM folders<br> WHERE parent_id IS NULL -- Root folder<br> UNION ALL<br> SELECT f.id, f.folder_name, f.parent_id<br> FROM folders f<br> INNER JOIN folder_tree ft ON f.parent_id = ft.id<br>)<br>3. Path Generation (Breadcrumbs)
WITH RECURSIVE breadcrumbs AS (<br> SELECT id, name, parent_id, name AS path<br> FROM categories<br> WHERE parent_id IS NULL<br> UNION ALL<br> SELECT c.id, c.name, c.parent_id, CONCAT(b.path, ' > ', c.name)<br> FROM categories c<br> INNER JOIN breadcrumbs b ON c.parent_id = b.id<br>)<br>Generate SQL for recursive CTE MySQL instantly with AI2sql — no technical expertise required.
