Recursive Queries

Recursive queries are SQL queries that refer to themselves within their own definition. They're used to process hierarchical or tree-structured data, where relationships exist between rows in the same table, like organizational charts, bill of materials, or social networks. Using WITH RECURSIVE clause, these queries iterate through the data until a certain condition is met, allowing you to traverse the hierarchy and extract related information.
