apoc.refactor.rename.type

Procedure

apoc.refactor.rename.type(oldType String, newType String, rels [Rel], config Map<String, Any>) - renames all relationships with type 'oldType' to 'newType'. If a list of relationships is provided, the renaming is applied to the relationships within this list only. == Signature

apoc.refactor.rename.type(oldType :: STRING?, newType :: STRING?, rels = [] :: LIST? OF RELATIONSHIP?, config = {} :: MAP?) :: (batches :: INTEGER?, total :: INTEGER?, timeTaken :: INTEGER?, committedOperations :: INTEGER?, failedOperations :: INTEGER?, failedBatches :: INTEGER?, retries :: INTEGER?, errorMessages :: MAP?, batch :: MAP?, operations :: MAP?, constraints :: LIST? OF STRING?, indexes :: LIST? OF STRING?)

Usage Examples

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

CREATE (mark:Engineer {name: "Mark", city: "London"})
CREATE (jennifer:Engineer {name: "Jennifer", city: "St Louis"})
CREATE (michael:Engineer {name: "Michael", city: "Dresden"})
CREATE (jim:Engineer {name: "Jim", city: "London"})
CREATE (alistair:Engineer {name: "Alistair", city: "London"})

MERGE (jim)-[:COLLEAGUES {since: date("2006-05-01")}]->(alistair)
MERGE (mark)-[:COLLEAGUES {since: date("2018-02-01")}]->(jennifer)
MERGE (mark)-[:COLLEAGUES {since: date("2013-05-01")}]->(michael);

The following changes the label on Mark, Jennifer, and Michael from Engineer to DevRel:

MATCH (person:Engineer)
WHERE person.name IN ["Mark", "Jennifer", "Michael"]
WITH collect(person) AS people
CALL apoc.refactor.rename.label("Engineer", "DevRel", people)
YIELD batches, total, timeTaken, committedOperations
RETURN batches, total, timeTaken, committedOperations;
Table 1. Results
