Sql 从clob数据类型xml值中提取数据

我有以下xml值，它存储在request_xml列中，是clob数据类型：

  <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
  <soapenv:Body>
    <ns:updateRechargeTicketResponse xmlns:ns="http://service.soap.CDRator.com">
      <ns:return xmlns:ax232="http://core.result.service.soap.CDRator.com/xsd" xmlns:ax233="http://core.data.soap.CDRator.com/xsd" xmlns:ax230="http://payment.result.service.soap.CDRator.com/xsd" xmlns:ax228="http://data.soap.CDRator.com/xsd" xmlns:ax231="http://result.service.soap.CDRator.com/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ax230:RechargeTicketResultDTO">
        <ax233:id xsi:nil="true"/>
        <ax232:code>0</ax232:code>
        <ax232:description>SOAP_GLOBAL_SUCCESS</ax232:description>
        <ax232:serviceUser xsi:nil="true"/>
        <ax232:success>true</ax232:success>
        <ax232:translationTag>SOAP_GLOBAL_SUCCESS</ax232:translationTag>
        <ax230:rechargeTicket xsi:type="ax228:RechargeTicketDTO">
          <ax233:id>201505131421267777</ax233:id>
          <ax233:billingGroupId>201505071857272816</ax233:billingGroupId>
          <ax233:code>BALANCE_DIRECTDEBIT</ax233:code>
          <ax233:dateCreated>2015-05-13</ax233:dateCreated>
          <ax233:dayOfMonth>0</ax233:dayOfMonth>
          <ax233:nextRechargeDate xsi:nil="true"/>
          <ax233:rechargeAmount>10.0</ax233:rechargeAmount>
        </ax230:rechargeTicket>
      </ns:return>
    </ns:updateRechargeTicketResponse>
  </soapenv:Body>
</soapenv:Envelope>

这是我的问题

您的名称空间在源XML和查询上不匹配

'http://data.soap.CDRator.com/xsd' as "ax233"

vs

尝试从源代码中删除

core.

，或者为

ax233

将

core.

添加到

XMLNAMESPACES

---

要修复错误，请执行以下操作：

ORA-19228: XPST0008 - undeclared identifier: prefix 'ax230' local-name 'ax230:rechargeTicket'
19228. 00000 -  "XPST0008 - undeclared identifier: prefix '%s' local-name '%s'"

您缺少ax230的命名空间声明，因此需要向XMLNAMESPACES添加：

'http://payment.result.service.soap.CDRator.com/xsd' as "ax230",

---

如果查询的格式更好，您可能会发现它更容易（除非您有理由这样做）。有关示例，请参见以下内容：

SELECT 
  t.error_code
, t.error_description
, t.code
FROM temp_soap_monitoring_topup sm
, XMLTABLE(
    XMLNAMESPACES (
      'http://schemas.xmlsoap.org/soap/envelope/' AS "soapenv",
      'http://service.soap.CDRator.com' as "ns",
      'http://core.data.soap.CDRator.com/xsd' as "ax2130",
      'http://webshop.result.service.soap.CDRator.com/xsd' as "ax2147",
      'http://core.signup.data.soap.CDRator.com/xsd' as "ns3",
      'http://service.soap.CDRator.com' as "ns5",
      'http://payment.result.service.soap.CDRator.com/xsd' as "ax230",      
      'http://core.data.soap.CDRator.com/xsd' as "ax233",
      'http://core.result.service.soap.CDRator.com/xsd' as "ax232"
    )

  , error_description VARCHAR2(100) PATH 'ax232:description/text()'
  , code              VARCHAR2(100) PATH 'ax230:rechargeTicket/ax233:code/text()'
  ) t

我已将您的XML放在本地数据库的一个表中，替换为

http://data.soap.CDRator.com/xsd'作为“ax233”，

和

'http://core.data.soap.CDRator.com/xsd'作为“ax233”，

我正在取回ID您好，我已经编辑了我的问题。当我仅使用此条件进行测试时，它工作正常，但现在我已经完成了完整的查询，它给出了一个错误。你能告诉我为什么它会出错吗？请查看我上次在查询中的交叉连接，其中有一个错误。请参阅我的编辑-您现在的查询中缺少ax230命名空间。在做了简短的整理后，再次编辑。您可以在两个XMLTables中执行此操作，一个用于请求xml，另一个用于响应xml。适当地构建路径，然后按照简单的相对路径选择多个列。

'http://payment.result.service.soap.CDRator.com/xsd' as "ax230",
