如何从配置单元（色相）的字符串下面提取以下数字“ CC0002308”

"fClassName":"NotifyAction",
  "fActions":[ {
    "type":"ConferenceAction",
    "properties": {
      "fClassName":"ConferenceAction",
      "fName":**"CC0002308"**,
      "fRecord":false,
      "fMuted":false,
      "fStartOnEnter":true,
      "fEndOnExit":false,
      "fHangupOnStar":true,
      "fExtraOptions": {
        "beepOnExit":true, "beepOnEnter":true, "enableImmediateInput":false
      }
    }
  }

  ]
}

Answer 1

您可以使用

get_json_object函数从json字符串中提取值！

Example:

select get_json_object(str,'$.fActions[0].properties.fName')fname 
    from ( //sample data
        select string('{"fClassName":"NotifyAction","fActions":[{"type":"ConferenceAction","properties":{"fClassName":"ConferenceAction","fName":"CC0002308","fRecord":false,"fMuted":false,"fStartOnEnter":true,"fEndOnExit":false,"fHangupOnStar":true,"fExtraOptions":{"beepOnExit":true,"beepOnEnter":true,"enableImmediateInput":false}}}]}') as str
        )e;

Output:

+---------+
|    fname|
+---------+
|CC0002308|
+---------+
