我需要从表BATCH_ID
和列BODY(数据类型:CLOB)中提取FND_SOA_BODY_PIECE
的数据,其中包含XML数据
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<tns1:InputParameters xmlns:tns1="http://xmlns.oracle.com/apps/gl/soaprovider/plsql/geas_gl_journal_pkg/geas_get_gl_data/">
<tns1:P_BATCH_TBL>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85380</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85345</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85364</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85356</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85374</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85358</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
</tns1:P_BATCH_TBL>
</tns1:InputParameters>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
我在下面尝试了这个,但它只给了我空值
SELECT xmltype(fsa.body).EXTRACT('/Envelope/Body/InputParameters/P_BATCH_TBL/P_BATCH_TBL_ITEM/BATCH_ID').getStringVal() FROM fnd_soa_body_piece;
有人可以帮忙解决这个问题吗?
答案 0 :(得分:0)
首先,请发布有效的XML,因为您显示的内容看起来像浏览器的屏幕,并且缺少结束标记并且包含无效字符。如果您的xml具有名称空间引用,则需要将它们包含在XPath中,并作为extract()函数的参数。这是一个例子:
with fnd_soa_body_piece as (
select xmltype(
'<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<SOAP-ENV:Body>
<tns1:InputParameters xmlns:tns1="http://xmlns.oracle.com/apps/gl/soaprovider/plsql/geas_gl_journal_pkg/geas_get_gl_data/">
<tns1:P_BATCH_TBL>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85380</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85345</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85364</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85356</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85374</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
<tns1:P_BATCH_TBL_ITEM>
<tns1:BATCH_ID>85358</tns1:BATCH_ID>
</tns1:P_BATCH_TBL_ITEM>
</tns1:P_BATCH_TBL>
</tns1:InputParameters>
</SOAP-ENV:Body>
</SOAP-ENV:Header>
</SOAP-ENV:Envelope>') body from dual
)
select extract(body,'/SOAP-ENV:Envelope/SOAP-ENV:Header/SOAP-ENV:Body/tns1:InputParameters/tns1:P_BATCH_TBL/tns1:P_BATCH_TBL_ITEM/tns1:BATCH_ID',
' xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:tns1="http://xmlns.oracle.com/apps/gl/soaprovider/plsql/geas_gl_journal_pkg/geas_get_gl_data/"').getStringVal()
from fnd_soa_body_piece
更新
要将结果作为SQL行集返回,您需要使用XMLTABLE函数,例如:
with fnd_soa_body_piece as (
select xmltype(
'<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<SOAP-ENV:Body>
<tns1:InputParameters xmlns:tns1="http://xmlns.oracle.com/apps/gl/soaprovider/plsql/geas_gl_journal_pkg/geas_get_gl_data/">
<tns1:P_BATCH_TBL>
<tns1:P_BATCH_TBL_ITEM>

</SOAP-ENV:Envelope>') body from dual
)
select t.batch_id
from fnd_soa_body_piece,
xmltable( xmlnamespaces(
