I want to extract the error code from the xml string which is CLOB data type in my oracle table. 我想从xml字符串中提取错误代码,该字符串是我的oracle表中的CLOB数据类型。 But when i tried to extract it gives me an error as 但是当我尝试提取它给我一个错误
ORA-19114: XPST0003 - error during parsing the XQuery expression:
LPX-00801: XQuery syntax error at 'return'
1 .w3.org/2001/XMLSchema-instance";for $i in //<Header errorCode= return $i
Here is my xml string which is stored in the RESPONSE column of PROVISIONING_LOG table: 这是我的xml字符串,存储在PROVISIONING_LOG表的RESPONSE列中:
<?xml version="1.0" encoding="ISO-8859-15"?>
<Order xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="sp.xsd">
<Header dateOfExecution="2014-10-01 00:03:06" externalId1="" messageId="1" orderId="0021417905" serviceProviderId="SP605" status="V" type="RES" errorCode="224" errorString="Subscription 201407162076606 not found." />

<OliControl oliId="1" subscriptionId="201407162076606" errorCode="224" errorString="Subscription 201407162076606 not found." status="V" />
<DEASUB />
</Oli>
</Body>
</Order>
Here is the query i tried: 这是我尝试过的查询:
select x.*
from TEMP_PROVISIONING_LOG PL
CROSS JOIN XMLTable(XMLNAMESPACES (
'http://core.signup.data.soap.CDRator.com/xsd' as "Header"),
'for $i in //Order return $i'
passing XMLType(PL.RESPONSE)
columns error_code varchar2(100) path 'Header/@errorCode') x;
I think you're after this: 我认为您是在追求:
with sample_data as (select xmltype('<?xml version="1.0" encoding="ISO-8859-15"?>
<Order xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="sp.xsd">
<Header dateOfExecution="2014-10-01 00:03:06" externalId1="" messageId="1" orderId="0021417905" serviceProviderId="SP605" status="V" type="RES" errorCode="224" errorString="Subscription 201407162076606 not found." />
<Body>
<Oli>
<OliControl oliId="1" subscriptionId="201407162076606" errorCode="224" errorString="Subscription 201407162076606 not found." status="V" />
<DEASUB />
</Oli>
</Body>
</Order>') response from dual)
select x.*
from sample_data tpl
cross join xmltable (XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema-instance' as "Header"),
'/Order' passing tpl.response
columns error_code varchar2(100) path 'Header/@errorCode') x;
ERROR_CODE
--------------------------------------------------------------------------------
224
ETA: Try this instead: 预计到达时间:
with TEMP_PROVISIONING_LOG as (select '<?xml version="1.0" encoding="ISO-8859-15"?>
<Order xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="sp.xsd">
