Aggregation can be computed over all the matching paths, or it can be further divided by introducing grouping keys. If a node with that label is created without a name, or if the name property is removed from an existing node with the Person label, the write operation will fail. 1.Relationship Types match (m)- r- (n) where r.label is not null return distinct (r.label) as label,r.name as name, 1 2 label 2.
