【问题描述】：
我将此 XML 存储在 CLOB 列中：
<SvcData><Status><StatusCode>EXI</StatusCode><StatusDesc></StatusDesc><StatusCodeAlt>000000</StatusCodeAlt><StatusDescAlt>OK</StatusDescAlt><StatusCodeHost></StatusCodeHost><StatusCodeHostSeverity>OK</StatusCodeHostSeverity><StatusCodeError>000000</StatusCodeError></Status><ConnectorResponse><ModuleResponse>

</LimitTypeDTO>
</limitList>
</ClientLimitAmountServiceDTO>
</services>
</content>
</previousData>
</concreteReturn>
</ModuleResponse></ConnectorResponse></SvcData>
我有这个查询来获取 XML 列并将其作为普通查询结果读取：
SELECT
Q.ServiceId,
Q.ServiceName,
S.LimitName,
W.Status,
X.LimitAmount
FROM
LTX_ENGINE_LOGGER LEL
LEFT JOIN xmltable('SvcData/ConnectorResponse/ModuleResponse/concreteReturn/previousData/content/services/ClientLimitAmountServiceDTO'
passing LEL.DATA_RECV
COLUMNS ServiceId NUMBER(10) path 'service',
ServiceName VARCHAR2(1000) path 'serviceName',
LimitNameXML XmlType path 'limitList/LimitTypeDTO/limitName',
StatusXML XmlType Path 'limitList/LimitTypeDTO/status',
LimitAmountXML XmlType Path 'limitList/LimitTypeDTO/limitAmount'
) Q ON (1=1)
LEFT JOIN xmltable('/limitName'
passing Q.LimitNameXML
COLUMNS LimitName VARCHAR2(1000) path '.') S ON (1=1)
LEFT JOIN xmltable('/status'
passing Q.statusXML
COLUMNS Status VARCHAR2(1000) path '.') W ON (1=1)
LEFT JOIN xmltable('/limitAmount'
passing Q.LimiteMontoXML
COLUMNS LimitAmount VARCHAR2(1000) path '.') X ON (1=1);
我有这个错误：
ORA-00932：不一致的数据类型：预期 - 得到 CLOB 00932. 00000 - “不一致的数据类型：预期的 %s 得到了 %s”
我需要得到这样的结果：
ServiceID ServiceName LimitName Status LimitAmount
210640 Pagos Virtuales TRANSACTION true 1000000.00
210640 Pagos Virtuales DAILY true 100000000.00
210640 Pagos Virtuales MONTHLY false -1.00
210733 Transferencias - Sebra TRANSACTION true 1000000.00
210733 Transferencias - Sebra DAILY true 100000000.00
210733 Transferencias - Sebra MONTHLY true -1.00
210643 Pagos Virtuales PSE TRANSACTION true 1000000.00
210643 Pagos Virtuales PSE DAILY true 100000000.00
210643 Pagos Virtuales PSE MONTHLY true -1.00
我该如何解决这个问题？
感谢您的帮助。
【问题讨论】：
-
传递 LEL.DATA_RECV -> 传递 xmltype(LEL.DATA_RECV)。在第一个 xmltable 语句中。 Oracle 不做 clob 和 xmltype 之间的自动转换。

谢谢@ArkadiuszŁukasiewicz。我修改了关于我想要获得的结果的原始帖子。您的提示有效，但结果我有很多很多行:(
