For example, take a hierarchy of tags: CREATE TABLE tag ( id INTEGER , name...bclassof = tag_hierarchy.id ) SELECT path FROM tag_hierarchy WHERE source = 'Oasis' ; path [Oasis, Rock, Music, Art] Graph Traversal The WITH RECURSIVE clause can be used to express graph traversal on arbitrary graphs. However, if the graph has cycles, th...e query must perform cycle detection to prevent infinite loops. One way to achieve this is to store the path of a traversal in a list and, before extending the path with a new edge, check whether its endpoint has been visited before (see the exam... - https://man.mtool.work/duckdb/1.3/sql/query_syntax/with.html
