带参数map的neo4j cypher set语句

Question

我很难找到如何将set cypher命令与参数映射一起使用的定义

备忘单说使用：SET n = {map}

我试过了：

START n = node(11379)
SET n = {Name: "Random Test Change"}

在我的服务器上

我收到错误： -

`.' expected but `=' found

我做错了什么？

Answer 1

map参数可以像这样使用：

String query = "START n = node(11379) SET n = {map}";

Map<String, String> myMap = new HashMap<String, String>();
myMap.put("Name", "Random Test Change");

Map<String, Object> queryParameters = new HashMap<String, Object>();
queryParameters.put("map", myMap);

ExecutionEngine engine = new ExecutionEngine(graphDatabase);
executionResult = engine.execute(query, queryParameters);
