The below query works fine in SDN 5. But in SDN 6 they throw errors.
@Query("UNWIND {0} AS row "
+ "MATCH (activity:Activity{guid:row.actGuid}), (actor:Actor{guid:row.ownerGuid})"
+ "CREATE (activity)<-[:OWNER_OF]-(actor)"
+ "RETURN activity.guid")
public List addOwnerOfActvities(List<Map<String,String>> ownerData);
can one tell me how I resolve this issue?
If there is another way to pass the list of maps to UNWIND then please tell me.
