在 orientdb 中使用嵌入式地图更新字段时出现问题

Question

我在 orientdb studio(2.1.12) 中有一个 javascript 函数，我试图用 json 更新名为 "node" 的字段，属性是在 uiJson Document/Class 中输入 embeddedMap。找到下面的代码：

 var dt = db.query("SELECT * from uijson");
    childUijson = dt[0].getRecord();
     node = childUijson.field('node');
     print(node )
    db.command('update uiJson set node=' + node + 'where @rid=18:1');
    return node;
       /*Print in oriendb console{0=inputs[{s_type=URL,source=,v_type=java.l,value=http://www.gmail.com}], next={0=1}, label=Open Url, type=OPEN_URL, component=FireFox, screenshot=false,chained=false,flowchartElement=startElement_1,left=0.12737921}}
*/
/*Return statement {
        "0": {
            "inputs": [
                {
                    "s_type": "URL",
                    "source": "",
                    "v_type": "java.lang.String",
                    "value": "http://localhost:8090/Automaton/"
                }
            ],
            "next": {
                "0": "1"
            },
            "label": "Open Url",
            "type": "OPEN_URL",
            "component": "FireFox",
            "screenshot": false,
            "chained": false,
            "flowchartElement": "startElement_1",
            "top": 0.4410876,
            "left": 0.12737921
        }           
        "@type": "d",
        "@version": 0
    }*/

Print 和 return 使用相同的变量 node 。在控制台中打印时，它使用 java object tostring() while returning 它给出了 Json.Please 帮助我用 Json 类型的嵌入式地图更新字段。

        }

}
