Hierarchical and recursive queries in SQL: Standards & Products

A hierarchical query is a type of SQL query that handles hierarchical model data. These are useful for working with databases of graph-structured data, such as river networks, file system trees, or threaded comments. They are special cases of more general recursive fixpoint queries, which compute transitive closures.
