apoc.export.graphml导出单个label进入恢复

 

1.导出具体某个label

CALL apoc.export.graphml.query("MATCH (n:User) RETURN n","User_bak_20250725.graphml",{ readLabels: true, useTypes: true })

 

2.模拟删除所有的label

MATCH (n) DETACH DELETE n;
drop index idx_user_name;

 

或是删除具体的label

MATCH (n:User) DETACH DELETE n

 

 

 

 

3.恢复刚才导出的label数据

CALL apoc.import.graphml('User_bak_20250725.graphml', {batchSize:1000, readLabels:true});
