I have below xml content. In oracle we are having cursor to extract the xml in row format. Do we have same like in POSGRES.
<TABLES>
<SEC_CALDAY> --Table name
<ROW> --3 rows formed with ROW tag
<SEC_DID>123</SEC_DID>
<SOURCE>TEXT</SOURCE>
<DAYS>31</DAYS>
<OCCR>24</OCCR>
<SEC_POLICYDETAILSID>45678</SE C_POLICYDETAILSID>
</ROW>
<ROW>
<SEC_DID>456</SEC_DID>
<SOURCE>TEXT</SOURCE>
<DAYS>31</DAYS>
<OCCR>24</OCCR>
<SEC_POLICYDETAILSID>45679</SE C_POLICYDETAILSID>
</ROW>
<ROW>
<SEC_DID>789</SEC_DID>
<SOURCE>TEXT</SOURCE>
<DAYS>31</DAYS>
<OCCR>24</OCCR>
<SEC_POLICYDETAILSID>45680</SE C_POLICYDETAILSID>
</ROW> </SEC_CALDAY>
</TABLES>
Oracle cursor to parse and textract the xml in row format.
CURSOR C_XMLSEC_CALDAY (B_XMLDOC11 IN XMLTYPE)
IS
SELECT EXTRACTVALUE (VALUE (T), '/ROW/SEC_DID') SEC_DID
, EXTRACTVALUE (VALUE (T), '/ROW/SOURCE') SOURCE
, EXTRACTVALUE (VALUE (T), '/ROW/DAYS') DAYS
, EXTRACTVALUE (VALUE (T), '/ROW/OCCR') OCCR
, EXTRACTVALUE (VALUE (T), '/ROW/SEC_POLICYDETAILSID') SEC_POLICYDETAILSID
FROM TABLE (XMLSEQUENCE (EXTRACT (B_XMLDOC11, '//ROW'))) T;
