Usage Examples

The examples in this section are based on the following sample graph:

MERGE (michael:Person {name: "Michael"})
WITH michael
CALL {
    WITH michael
    UNWIND range(0, 100) AS id
    MERGE (p:Person {name: "Person" + id})
    MERGE (michael)-[:KNOWS]-(p)
    RETURN count(*) AS friends
}

CALL {
    WITH michael
    UNWIND range(0, 50) AS id
    MERGE (p:Person {name: "Person" + id})
    MERGE (michael)-[:FOLLOWS]-(p)
    RETURN count(*) AS follows
}

RETURN friends, follows;
