Usage Examples

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

CREATE (:Person {name:'Tom',age: 40})
CREATE (:Person {name:'Will',age: 35})
CREATE (:Person {name:'David', children: ['Anne','Sam','Paul']})
CREATE (:Person {name:'John', cars: ['Class A','X3','Focus']})
CREATE (:Person {name:'Ryan', salary1:1800, salary2:1500});

The following adds 10 to the property age for Tom:

MATCH (n:Person {name:'Tom'})
CALL apoc.atomic.add(n,'age',10,5)
YIELD oldValue, newValue
RETURN oldValue, newValue;
