My Requirement output should be like this

308221235 Jane DOE
Please help me on this anyone
i Writtened query like this
SELECT DISTINCT t1.firstname fnname,
t1.LastName lstname,
t2.polno
FROM
( SELECT xData doc FROM dual
) temp_table,
XMLTable (
'/TXLife/TXLifeRequest/OLifE' passing doc
columns
person xmltype path '//Party[@id=/OLifE/Relation[RelationRoleCode/@tc=32]/@RelatedObjectID]',
holding xmltype path '//Holding [@id=/OLifE/Relation[RelationRoleCode/@tc=50]/@RelatedObjectID][HoldingTypeCode/@tc=2]'
) t,
XMLTable (
'/Party' passing t.person
columns
firstname VARCHAR2(200) path 'Person/FirstName',
LastName VARCHAR2(200) path 'Person/LastName'
)t1,
XMLTable(
'/Holding' passing t.holding
columns
polno VARCHAR2(20) path 'Policy/PolNumber'
)t2
IN query Xdata is above XML INPUT
The output is writting like this but in output i am typing few columns only
PolNumber FirstName LastName
308221234 John Doe
308221235 John Doe
308221235 Jane DOE
308221234 Jane DOE

Answer 1

Hi Odie,
First of all sorry for the delayed replay and thank you very much for the solution provided by you, using which I am able to retrieve the required output after doing small changes. As mentioned earlier this functionality we are using in reading XML file which we receive as CLOB input parameter to procedure. This XML file will contain 50 multiple records which need to be read inside the procedure, using the logic provided by you. To read these 50 records it is taking 2 seconds of time.
Now we got requirement to read up to 1500 records which will be supplied by CLOB field as input parameter to the procedure.
But we are facing really a big challenge over here. Initially in testing phase we are trying to read just 100 records for which the time taking from point 1 to point 2(Mentioned below, that is going in to the loop) is around 60 sec. As you know this is not acceptable. So can you please help me to reduce this time frame?
Do Let me know if you have any questions.
