运行多个语句

apoc.cypher.runMany(statement STRING, params MAP<STRING, ANY>, config MAP<STRING, ANY>) - 运行每个以分号分隔的语句，并返回语句结果的摘要。

目前没有模式操作。

此过程对于执行多个 Cypher 语句非常有用。我们可以通过运行以下查询，在一个语句中创建节点，并在另一个语句中创建指向自身的引用关系

CALL apoc.cypher.runMany(
  'CREATE (n:Node {name:$name});
   MATCH (n {name:$name})
   CREATE (n)-[:X {name:$name2}]->(n);',
  {name:"John", name2:"Doe"}
);

{constraintsRemoved: 0, indexesRemoved: 0, nodesCreated: 0, rows: 0, propertiesSet: 1, labelsRemoved: 0, relationshipsDeleted: 0, constraintsAdded: 0, nodesDeleted: 0, indexesAdded: 0, labelsAdded: 0, relationshipsCreated: 1, time: 0}

如果我们不想查看每个 Cypher 语句的统计信息，可以设置 statistics: false

CALL apoc.cypher.runMany(
  'CREATE (n:Node {name:$name});
   MATCH (n {name:$name})
   CREATE (n)-[:X {name:$name2}]->(n);',
  {name:"John", name2:"Doe"},
  {statistics: false}
);
