 If you want this to be a fast thing to query for, you can put the array
 length in a separate property on the nodes, and then create an index for
 it. Then change your queries to be for `v.length = 1`, etc.

I have another question, please!
What about if I would like to delete a specific value from an array without
knowing the indices of it in the array  (example array[10,20,30) and the
result will be [10,30]).
any suggestions, please? I'll be so grateful!

[Neo4j] Neo4j: count the size of array

2018-05-07 Thread Ebtihel Hannachi 
Hi, 
I am new in graph databases and I need your help, please!
so I have created a set of nodes, every node has as properties name and an 
array of integers.
I would like to know how to get all nodes have only a single integer???
I tried this query but it gave no results "MATCH (v) WITH length(v.value) 
as size WHERE size=1 RETURN v.name".
