Procedurescan be called stand-alone withCALL procedure.name(); But you can also integrate them into your Cypher statements which makes them so much more powerful. Load JSON example WITH'https://raw.githubusercontent.com/neo4j-contrib/neo4j-apoc-procedures/4.4/core/src/test/resources/person.json'...
auth=( getenv("NEO4J_USERNAME"), getenv("NEO4J_PASSWORD") ) ) with driver.session() as session: # truncate the db session.run("MATCH (n) DETACH DELETE n") # create constraints for q in constraint_queries: if q.strip() != "": session.run(q) # import the ...
Using the standardJOINsyntax, the driver will translate the query to a simple pattern match, so that SELECTp."v$person_id", name, title, rolesFROMPerson pJOINPerson_ACTED_IN_Movie pmONpm.v$person_id=p.v$idJOINMovie mONm.v$id=pm.v$movie_idWHEREtitle='The Matrix'ORDER BYtitle, name ...

Cypher statements typically have multiple clauses, each of which performs a specific task, for example: Cypher 语句会有多个子句,每个子句执行特定的任务,例如: create and match patterns in the graph filter, project, sort, or paginate results ...

When you useStackobjects for sending multiple statements at once, it will return you aResultCollectionobject containing a collection ofResults. So you need to iterate the results before accessing the records. The Client provides a Transaction object that ease how you would work with transactions. ...
The following Cypher statements define the unique constraint fornameproperty ofCharacternodes. 以下Cypher 语句为角色节点的名称属性定义了唯一约束。 CREATE CONSTRAINT IF NOT EXISTS FOR (c:Character) REQUIRE IS UNIQUE; Next, you need to import the CSV file. Even though the Dune CSV file has only 10...
You can create multiple nodes at once by separating each node with a comma: xxxxxxxxxx CREATE(a:Album{Name:"Killers"}),(b:Album{Name:"Fear of the Dark"}) RETURNa,b Or you can use multipleCREATEstatements: xxxxxxxxxx CREATE(a:Album{Name:"Piece of Mind"}) ...
The rest of the query is familiar since it uses multiple MERGE clauses. Then, we reach the WITH clause, which uses FOREACH constructs with IN CASE statements. These are used to conditionally create relationships based on the match outcome. If the home team wins, it creates a 'WON' relatio...
