Hey all a beginner neo4j student here o/ I created 40 nodes20:EMPLOYEE and 20:ORGANIZATION
nodes
Employee nodes have the owns_organizationNr
property
Organization nodes have the ownedBy_organizationNr property
some of those nodes have the same value and I tried the query below to create relationships between those who match by the property value and insert the n1.owns_organizationNr
property and value into to new relationship but something is missing can you guys help me, please?
MATCH (n1:EMPLOYEE) , (n2:ORGANIZATION)
WHERE
HAS(n1.owns_organizationNr) AND HAS(n2.ownedBy_organizationNr) AND n1.owns_organizationNr = n2.ownedBy_organizationNr
CREATE (n1) -[:OWNS_ORG{n1.owns_organizationNr}]->(n2)
The query is doing a cartesian product so it is resulting to a lot of rows. You can use below query. Also, there is a typo error on the CREATE statement. I also fix it in the last line.
MATCH (n1:EMPLOYEE) WHERE n1.owns_organizationNr is not null
WITH n1
MATCH (n2:ORGANIZATION)
WHERE n2.ownedBy_organizationNr is not null AND n1.owns_organizationNr = n2.ownedBy_organizationNr
CREATE (n1) -[:OWNS_ORG{owns_organizationNr: n1.owns_organizationNr}]->(n2)
