如何解决如何修复密码查询中的永恒执行 - Neo4j 图形数据库？
我正在使用密码语言查询和 apoc 库处理将常见弱点枚举目录（.json 文件）导入 Neo4j 图形数据库。尽管我正确导入了字段：Weaknesses、Views、External_References，但我在导入字段时遇到了执行问题（没有任何错误）：Categories 正在执行而没有结束.下面我展示了 .json 文件的结构和我的密码。
"Weakness_Catalog": {
"Weaknesses": {"Weakness":[...]}
"Categories": {"Category":[...]}
"Views": {"View":[...]}
"External_References": {"External_Reference":[...]}
}
密码查询
经过多次测试，我认为逻辑错误在最后两部分 [with value....(catRef)] 之间，没有它们，查询在正常时间执行得很好。我还更改了设置参数。由于错误 (cypher.lenient_create_relationship = true) 在 db 配置文件中。我测试了不同的导入序列，但结果相同（弱点、类别、视图、外部引用等）

解决方法
所以，问题是每次我使用 with 时，我都在嵌套循环中工作。嵌套循环越多，查询越慢。加快速度的一个好方法是在可能的情况下创建更简单的查询。
例如在json文件中：
"Weakness_Catalog": {
"Weaknesses": {"Weakness":[...]}
"Categories": {"Category":[...]}
"Views": {"View":[...]}
"External_References": {"External_Reference":[...]}
}
我将针对弱点执行一项查询，一项针对类别，一项针对视图，一项针对 External_References。
