ORA-19228: XPST0008 - oracle 中未声明的标识符 sql

Question

我有下面提到的 xml 字符串，我想从 xml 字符串中提取代码。我在下面写了 select 查询以从 <ax2140:code>0</ax2140:code> 中提取值 0 但我收到错误

ORA-19228: XPST0008 - undeclared identifier: prefix 'ax2140' local-name 'ax2140:code'
19228. 00000 -  "XPST0008 - undeclared identifier: prefix '%s' local-name '%s'"

这是我的 xml 字符串-

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>

         </ns:return>
      </ns:placeShopOrderResponse>
   </soapenv:Body>
</soapenv:Envelope>

这是我的 select 查询：

SELECT ID,xt_code.CODE
FROM TEMP_SOAP_MONITORING_MSP sm
CROSS JOIN XMLTable(XMLNAMESPACES (
      'http://core.result.service.soap.CDRator.com/xsd' as "ax2140_code"
    ),
    'for $i in //ax2140:code return $i'
    passing XMLType(sm.RESPONSE_XML)
    columns "CODE" VARCHAR2(50) path '/') xt_code;

Answer 1

在查询中使用 "ax2140" 而不是 "ax2140_code"。
