我的问题是如何访问 3 个 JSON.Data 元素并创建组合响应。我知道这不是有效的 JSON 并且 FLDR 是重复键。这也不是一个数组。我如何访问这些元素并创建这样的组合响应？

{
    "result1": {
        "userId": 1,
        "id": 1,
        "title": "delectus aut autem",
        "completed": false
    },
    "result2": {
        "userId": 1,
        "id": 2,
        "title": "quis ut nam facilis et officia qui",
        "completed": false
    },
    "result3": {
        "userId": 1,
        "id": 3,
        "title": "fugiat veniam minus",
        "completed": false
    }
}

非常感谢任何帮助。

如果您有包含该结构的消息树，那么您可以访问它的任何部分 - 无论它是否是有效的 JSON 文档。

您是否尝试过在 ESQL 中编写一个普通的 FOR 循环来迭代出现的 FLDR？

注意：此代码完全未经测试，可能包含语法错误和缺陷...

DECLARE index INTEGER 1;
FOR refFLDR AS InputRoot.ComIbmGroupCompleteNode.Group.msg.Replies.FLDR[] DO
   DECLARE fieldName 'Result' || index;
   CREATE LASTCHILD OF OutputRoot.JSON.Data TYPE Name NAME fieldName FROM refFLDR;
   SET index = index + 1;
END FOR;
