问题描述

我知道这个问题已经被很多人问过了
对于我的研究，这是之前提出的一些问题

1. 2.3.0 之前的版本

   匹配 (n)可选匹配 (n)-[r]-()删除 n,r

   文档

   I know this question is asked by many people already
   for my research, here's some questions asked before

   1. How to delete all relationships in neo4j graph?
   2. https://groups.google.com/forum/#!topic/neo4j/lgIaESPgUgE

   But after all, still can't solve our problems,
   we just want to delete "ALL" nodes and "ALL" relationships

   suppose delete "ALL" can see there are left 0 nodes 0 properties and 0 relationships

   This is the screenshot i took after executing the delete "ALL" suggested by forum

   My question still the same, how do delete all nodes and all relationships in neo4j

   解决方案
