[Neo4j] Neo4j: count the size of array

[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".

[hema]

Hi,


I am very new to neo4j database. Just started trying out neo4j spatial 
plugin.
Excuse me if my doubts are silly. As it is very new for me facing little 
difficult to start.


I want to save a list of polygon data to neo4j database and then query with 
some latitude and longitude to check whether the location is within the 
polygon.

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.

Thank you so much, for your response.

*Please find the attachements*

I want it to be done using Java. I found through some documentation we can 
do it using GraphRepository and SpatialRepository.

I am trying to do using neo4j-spatial dependency.But i am unable to add 
GraphRepository and SpatialRepository to my project. 
I have attached pom.xml of my project .Please help me with this issue.

That was old code in the 4 year old version of Spring Data Neo4j which is
no longer maintained.

For now you'll have to use the procedures.

It's also better to go with a Neo4j server.
