Usage Examples

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

MERGE (joe:Person {name: "Joe"})
MERGE (ryan:Person {name: "Ryan"})
MERGE (ryan)-[:FOLLOWS {since: datetime("2020-11-04")}]->(joe);

MATCH (person:Person {name: "Ryan"})
RETURN apoc.hashing.fingerprint(person) AS output;

Results
output
"81C99DD6C9382C4E01A1873F9E818CE0"

MATCH ()-[rel:FOLLOWS]->()
RETURN apoc.hashing.fingerprint(rel) AS output;

Results
output
"C5A4B9FA273CC723D96BF93FFDD42858"

RETURN apoc.hashing.fingerprint({name: "Michael"}) AS output;
