[英]Can't extract the data from xml values in oracle sql
I have the following 2 xml value which is similar and which is stored in the request_xml column and which is clob data type: 我有以下2个xml值,它们相似,存储在request_xml列中,并且是clob数据类型:
<?xml version='1.0' encoding='utf-8'?>

I want to use only 1 select query to extract the BillingGroupId from this 2 xml values. 我只想使用1个选择查询从这2个xml值中提取BillingGroupId。 Is it possible or do i want to use separate select query to extarct BillingGroupId for this 2 xml values?
是否可能或者我想使用单独的选择查询来为这2个xml值选择BillingGroupId? I want to extract the
billingGroupID
value from this xml value but its not returning anything. 我想从此xml值中提取
billingGroupID
值,但不返回任何内容。 I am doing a small mistake in my select query which i am not able to identify. 我在无法识别的选择查询中犯了一个小错误。
Here is my query : 这是我的查询:
SELECT xt_billingGroupId.BILLING_GROUP_ID
FROM TEMP_SOAP_MONITORING_TOPUP sm
CROSS JOIN 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://core.result.service.soap.CDRator.com/xsd' as "ax232"
),
'for $i in //ns5:billingGroupId return $i'
passing XMLType(sm.REQUEST_XML)
columns "BILLING_GROUP_ID" VARCHAR2(100) path '/') xt_billingGroupId
CROSS JOIN XMLTable(XMLNAMESPACES (
'http://core.result.service.soap.CDRator.com/xsd' as "ax232"
)
Also one variant 也是一种
select xt_billingGroupId.* from x,
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://core.result.service.soap.CDRator.com/xsd' as "ax232"
),
'//ns5:rechargeTicket'
passing x
columns "BILLING_GROUP_ID" VARCHAR2(100) path 'ax2130:billingGroupId',
lineitem XMLType PATH '/') xt_billingGroupId ;
You're trying to access a node with no namespace prefix, so in the default namespace, but within a node that has a specific namespace prefix, ns5
. 您尝试访问没有名称空间前缀的节点,因此要访问默认名称空间,但要访问具有特定名称空间前缀
ns5
。 You could do that with local-name()
: 您可以使用
local-name()
来做到这一点:
SELECT xt_billingGroupId.BILLING_GROUP_ID
FROM TEMP_SOAP_MONITORING_TOPUP sm
CROSS JOIN XMLTable(XMLNAMESPACES (
'http://schemas.xmlsoap.org/soap/envelope/' AS "S",
'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://core.result.service.soap.CDRator.com/xsd' as "ax232"
),
'//ns5:rechargeTicket/*[local-name()="billingGroupId"]'
passing XMLType(sm.REQUEST_XML)
columns "BILLING_GROUP_ID" VARCHAR2(100) path '/') xt_billingGroupId;
BILLING_GROUP_ID
--------------------------------------------------------------------------------

Or by wild-carding the namespace: 或通过通配符命名空间:
...
'//ns5:rechargeTicket/*:billingGroupId'
passing XMLType(sm.REQUEST_XML)
columns "BILLING_GROUP_ID" VARCHAR2(100) path '/') xt_billingGroupId
If you want it to be flexible you could just use the wild-card without referring to the containing node at all; 如果您希望它具有灵活性,则可以只使用通配符,而无需完全引用包含节点。 and then you don't need the XMLNameSpaces definition either.
然后您也不需要XMLNameSpaces定义。 With your two sample XMLs:
使用您的两个示例XML:
SELECT xt_billingGroupId.BILLING_GROUP_ID
FROM TEMP_SOAP_MONITORING_TOPUP sm
CROSS JOIN XMLTable('//*:billingGroupId'
passing XMLType(sm.REQUEST_XML)
columns "BILLING_GROUP_ID" VARCHAR2(100) path '/') xt_billingGroupId
BILLING_GROUP_ID
