Du kan gå tillbaka till elevens syskon s_days
nod:
select h.PlanCodeCode, b.amount, b.pcode, b.child1_amount, b.child2_amount
from t
cross join
xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
'/SSO_XML'
passing t.xml
columns PlanCodeCode varchar2(100) path './PlanCode/@PlanCodeCode',
attributes xmltype path './PlanCode'
) h
left join xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
'PlanCode/S_DAYS/STUDENT/DIVISION'
passing h.attributes
columns node_level for ordinality
, amount number path '@Amount'
, pcode varchar2(10) path './../../@PCODE'
, child1_amount number path './../../../S_DAYS[@PCODE="Child1"]/AdditonalFare/AdditonalFareAmount/@Amount'
, child2_amount number path './../../../S_DAYS[@PCODE="Child2"]/AdditonalFare/AdditonalFareAmount/@Amount'
) b on 1=1;
Eller så kan du hämta barnen från den första XML-tabellen, om du alltid vill se dem även om det inte finns några studentnoder:
select h.PlanCodeCode, b.amount, b.pcode, h.child1_amount, h.child2_amount
from t
cross join
xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
'/SSO_XML'
passing t.xml
columns PlanCodeCode varchar2(100) path './PlanCode/@PlanCodeCode',
attributes xmltype path './PlanCode',
child1_amount number path './PlanCode/S_DAYS[@PCODE="Child1"]/AdditonalFare/AdditonalFareAmount/@Amount',
child2_amount number path './PlanCode/S_DAYS[@PCODE="Child2"]/AdditonalFare/AdditonalFareAmount/@Amount'
) h
left join xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
'PlanCode/S_DAYS/STUDENT/DIVISION'
passing h.attributes
columns node_level for ordinality
, amount number path '@Amount'
, pcode varchar2(10) path './../../@PCODE'
) b on 1=1;
För övrigt, eftersom du är på 12c kan du använda cross apply
och outer apply
- den senare istället för den yttre kopplingen med dummy on 1=1
skick.
select h.PlanCodeCode, b.amount, b.pcode, h.child1_amount, h.child2_amount
from t
cross apply
xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
'/SSO_XML'
passing t.xml
columns PlanCodeCode varchar2(100) path './PlanCode/@PlanCodeCode',
attributes xmltype path './PlanCode',
child1_amount number path './PlanCode/S_DAYS[@PCODE="Child1"]/AdditonalFare/AdditonalFareAmount/@Amount',
child2_amount number path './PlanCode/S_DAYS[@PCODE="Child2"]/AdditonalFare/AdditonalFareAmount/@Amount'
) h
outer apply xmltable(xmlnamespaces(default 'http://www.w3.org/2001/XMLSchema'),
'PlanCode/S_DAYS/STUDENT/DIVISION'
passing h.attributes
columns node_level for ordinality
, amount number path '@Amount'
, pcode varchar2(10) path './../../@PCODE'
) b;
Alla dessa får samma resultat med dina exempeldata:
