Cypher creates number as a long. How do I create an integer?

I have a problem with types in Neo4j. I am trying with the following query to create a node with a variable number with the integer value 1:

Create (n:Test{numer:1})

When I am getting the node from the Java api I am getting an error telling me that it is of type long.

How can I see of what type a variable is saved in Neo4J? How can I save an integer?

Solution

  • If you use Cypher or REST API then Neo4j (internally) use Java's Long for integer values and Java's Double for floating point values.

    In Java API you can use following datatypes

    • boolean
    • byte
    • short
    • int
    • long
    • float
    • double
    • char
    • String
