initial input comnand:
:auto USING PERIODIC COMMIT 500 load csv with headers from "https://lovecandyhsu.neocities.org/relations.csv" as csvLine MATCH (s1:Station { id: toInteger(csvLine.fromId)}),(r:Route { id: toInt(csvLine.route_informationId)}),(s2:Station { id: toInt(csvLine.toId)}) CREATE UNIQUE(s1)<-[:FROM]->(r) CREATE UNIQUE(r)<-[:TO]->(s2) RETURN csvLine
Solution 1:[1]
The 'CREATE UNIQUE' clause was deprecated in Neo4j version 3.2
The MERGE caluse does the trick now.
Ideally, you should be good to go just by replacing 'CREATE UNIQUE' with 'MERGE'.
