Modify the node label

Match to the node to be deleted , Use REMOVE Delete the label to be deleted , Then set a new label
like this :

MATCH (n:OLD_LABEL) 
REMOVE n:OLD_LABEL 
SET n:NEW_LABEL

for example :

MATCH (n:User:Teacher) REMOVE n:Student  RETURN n

apoc.periodic.iterate how set label Change node label
Published on 1 Years ago author stringso 1133 Views come from Question and answer
as follows , add set n:row.label_type That would be a mistake
CALL apoc.periodic.iterate(‘with "select * from tables limit 10 " as sql call apoc.load.jdbcParams(“jdbc:mysql://xxxx:3306/xx?user=xx&password=xx”, sql, []) yield row return row’,’ MERGE (n:xx {id:row.id}) set n:row.label_type,n.name=row.namet’,{batchSize:10000,iterateList:true})

Modify the relationship label

Modifying relationships cannot be directly modified like nodes , It can't pass type() Function modification , So you need to delete the old relationship , Add a new relationship , Copy properties .
as follows :

MATCH (n)-[r:OLD_RELATION]->(m)
CREATE (n)-[r2:NEW_RELATION]->(m)
SET r2 = r //  Here is the copy attribute 
WITH r
DELETE r
