I am sorry for that "rich "-relationship .It means that relationship has properties. Now I need to do it using one query . I remember that at neo4j manual,it says that "This query isn’t for deleting large amounts of data, but is nice when playing around with small example data sets" for DELETE.I need to know wether it has other syntax to do it. Can you help me? Thank you very much!
