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 query changes the relationship property since
to from
for all relationships:
MATCH ()-[rel]->()
WITH collect(rel) AS rels
CALL apoc.refactor.rename.typeProperty("since", "from", rels)
YIELD batches, total, timeTaken, committedOperations
RETURN batches, total, timeTaken, committedOperations;
batches | total | timeTaken | committedOperations |
---|---|---|---|

The following query returns all the paths in our graph after this refactoring has been done:
MATCH path = ()-[]->()
RETURN path
