Is there are way wherein I can prevent merge in cypher to not create node
if its not present. I have a query like
FOREACH(p in {props} |
MERGE (I:Interface {IfIPAddress:p.OrigIPAddress})
MERGE (I2:Interface {IfIPAddress:p.TermIPAddress})
MERGE (I)-[r:link]->(I2)
SET r = p)
where the props is a map of arrays.
In the first and second merge I do not want I and I2 to be created. Is it
possbile?
I am using neo4j version 2.0.1.0.
Please let me know if you need any more information
