Question

我苦苦尋找的如何使用設置暗號命令與參數圖

速查表定義說使用：SET n = {map}

我曾嘗試：

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

我的服務器上

我得到錯誤： -

`.' expected but `=' found 

我在做什麼錯？

Answer 1

地圖參數可以這樣來使用：

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);
