Answer 1

You can install the APOC library and then use apoc.merge.relationship

apoc.merge.relationship(startNode, relType, {key:value, ...}, {key:value, ...}, endNode) - merge relationship with dynamic type

load csv with headers from "file:///d:/Resources/Neo4j/person-rel.csv" as p
match (a:PERSON) where a.name=p.name1
match (b:PERSON) where b.name=p.name2
call apoc.merge.relationship(a,p.REL,{},{},b) yield rel
return count(*);
