Recursive CTEs in SQL

Recursive CTEs use a WITH clause that references itself to traverse hierarchical data.

Structure: anchor query (base case) UNION ALL recursive query (inductive case).

Useful for org charts, category hierarchies, and path finding in graphs.

Recursion depth can be limited with MAX_RECURSION_DEPTH hint.

Performance improves with indexed foreign keys between recursive levels.
