解析 JSON 对象以在 Apex 项目 select 列表中使用

Question

我正在尝试将 JSON 对象解析为 APEX select 列表。有多种方法可以解析 JSON 对象，但我还没有遇到或想出一种方法来解析 JSON 对象并将其用作 Apex 应用程序中的 select 列表。大多数问题都围绕着从 Apex 数据生成 JSON。任何帮助，将不胜感激。谢谢！

我要解析的数据（更简单的例子）如下：

    {
  "verumModelObjectName": "Address",
  "verumObjectList": [
    {
      "locationID": "20005",
      "country": "ARE"
    },
    {
      "locationID": "31083",
      "country": "ARE"
    },
    {
      "locationID": "31118",
      "country": "ARE"
    },
    {
      "locationID": "32185",
      "country": "ARE"
    },
    {
      "locationID": "32138",
      "country": "ARE"
    },
    {
      "locationID": "32070",
      "country": "ARE"
    },
    {
      "locationID": "32094",
      "country": "ARE"
    },
    {
      "locationID": "20006",
      "country": "ARG"
    },
    {
      "locationID": "32196",
      "country": "ARG"
    },
    {
      "locationID": "41057",
      "country": "ARG"
    },
    {
      "locationID": "31032",
      "country": "ARG"
    },
    {
      "locationID": "33212",
      "country": "ARG"
    },
    {
      "locationID": "3558",
      "country": "ARG"
    },
    {
      "locationID": "33126",
      "country": "ARG"
    },
    {
      "locationID": "31007",
      "country": "ARG"
    },
    {
      "locationID": "33127",
      "country": "ARG"
    },
    {
      "locationID": "31100",
      "country": "ASM"
    },
    {
      "locationID": "20008",
      "country": "AUS"
    },
    {
      "locationID": "20591",
      "country": "AUS"
    },
    {
      "locationID": "31125",
      "country": "AUS"
    }]
  "statusCode": 200
}

你有没有在 5.0 中检查 apex_json 包 https://docs.oracle.com/cd/E59726_01/doc.50/e39149/apex_json.htm#AEAPI29640

您可以使用此包解析您的数据然后对于 select 列表，您应该创建一个动态 select 列表，其中包含 d 显示和 r return 值，如下所示。它应该工作

 select col1 d, col2 r
from xmltable (
        '/json/verumObjectList/row'
        passing apex_json.to_xmltype('

    {
  "verumModelObjectName": "Address",
  "verumObjectList": [
    {
      "locationID": "20005",
      "country": "ARE"
    },
    {
      "locationID": "31083",
      "country": "ARE"
    },
    {
      "locationID": "31118",
      "country": "ARE"
    },
    {
      "locationID": "32185",
      "country": "ARE"
    },
    {
      "locationID": "32138",
      "country": "ARE"
    },
    {
      "locationID": "32070",
      "country": "ARE"
    },
    {
      "locationID": "32094",
      "country": "ARE"
    },
    {
      "locationID": "20006",
      "country": "ARG"
    },
    {
      "locationID": "32196",
      "country": "ARG"
    },
    {
      "locationID": "41057",
      "country": "ARG"
    },
    {
      "locationID": "31032",
      "country": "ARG"
    },
    {
      "locationID": "33212",
      "country": "ARG"
    },
    {
      "locationID": "3558",
      "country": "ARG"
    },
    {
      "locationID": "33126",
      "country": "ARG"
    },
    {
      "locationID": "31007",
      "country": "ARG"
    },
    {
      "locationID": "33127",
      "country": "ARG"
    },
    {
      "locationID": "31100",
      "country": "ASM"
    },
    {
      "locationID": "20008",
      "country": "AUS"
    },
    {
      "locationID": "20591",
      "country": "AUS"
    },
    {
      "locationID": "31125",
      "country": "AUS"
    }],
  "statusCode": 200
}


')
        columns
           col1 number path '/row/locationID',
           col2 varchar2(5) path '/row/country' );
