Můžete jít zpět k sourozenci studenta s_days
uzel:
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'),

passing h.attributes
columns node_level for ordinality
, amount number path '@Amount'
, pcode varchar2(10) path './../../@PCODE'

, child2_amount number path './../../../S_DAYS[@PCODE="Child2"]/AdditonalFare/AdditonalFareAmount/@Amount'
) b on 1=1;
Nebo můžete získat děti z první XMLTable, pokud je chcete vždy vidět, i když tam nejsou žádné studentské uzly:
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;
Mimochodem, když jste na 12c, můžete použít cross apply
a outer apply
- druhé místo vnějšího spojení s figurínou on 1=1
podmínka.
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;
Každý z nich získá stejný výsledek s vašimi ukázkovými daty:
