Conversion of extractValue XMLTABLE
Hello world
I recently discovered extractValue is obsolete and I am trying to convert my code XMLTABLE.
Examples, I found on this forum and other places, I think I have the right to the syntax, but it does not return all the values of the XMLTABLE call.
My version is: Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit
SELECT xt.po_num, xt.vendor,
extractValue (p_t.po_xml_data, ' / PurchaseOrder/PO_Num ',' xmlns = "http://tempuri.org/" ' ")
OF p_t po_table,.
XMLTable (XMLNamespaces (default 'http://tempuri.org/'), )
' / PurchaseOrder'
PASSAGE po_table.po_xml_data
COLUMNS
po_num PATH VARCHAR2 (12) "PO_Num."
provider path ACCESS of VARCHAR2 (12) "PO_Vendor") xt
where p_t.po_xml_data_id = '366000000008143';
The "extractValue" returns the number of PO for this record. The other two columns are null.
The XML data in the po_xml_data of XMLTYPE column in this record looks like this:
"< PurchaseOrder xmlns = 'http://tempuri.org/" "xmlns: xsi ="http://www.w3.org/2001/XMLSchema-instance"> " "
"< PO_Num xmlns:ns4 ="http://tempuri.org/"ns4:IsFlagged ="false"> 123454 < / PO_Num >"
"< PO_Vendor xmlns:ns4 ="http://tempuri.org/"ns4:IsFlagged ="false"> HP < / PO_Vendor >"
< / PurchaseOrder >
I appreciate any help you can offer.
Thank you
Jack
Hi Jack,
You have the right XMLTABLE syntax.
But I do not reproduce the behavior you describe.
When I tried to run the query, I get:
ORA-00904: "PO_TABLE." "" PO_XML_DATA ": invalid identifier
Shouldn't this part: PASS po_table.po_xml_data
read this instead: p_t.po_xml_data of PASSAGE?
Once the problem is corrected, I have another error, which is, in my view, the real issue here:
SQL> create table po_table (po_xml_data_id varchar2(30), po_xml_data xmltype);
Table created.

ORA-19025: EXTRACTVALUE returns value of only one node
After removing the EXTRACTVALUE call, we can see why the error occurred.
Oracle retrieves the attribute node, as if it were an element, thus feeding two nodes to EXTRACTVALUE.
This is a bug, always present in the most recent version of today (12.1.0.2), but it occurs only when the attribute is qualified namespace.

Vincent,
using the query below, but I have to remove '' the case, he will ask error,
In the face of an error, it is always useful to see what is the real error.
In your example, it's because of the break line appearing before the prologue (thepart).
Remove it and it should be OK.
In addition, there is no point uses EXTRACTVALUE (discouraged) at the screening can be fully defined in the clause of COLUMNS:
SELECT t.* FROM XMLTABLE ( '/ScanData/BOX' passing XMLTYPE(' -

Could someone give me a tip how to retrieve the values of 'element '?Best regards, Hans
Looks like you hit an old bug in 10g.
Try with the CURSOR_SHARING_EXACT indicator:
Select / * + CURSOR_SHARING_EXACT * / x.*
of tmp_table t
xmltable)
XmlNamespaces)
"http://schemas.xmlsoap.org/soap/envelope/" as "env".

)
, ' / env:Envelope / env:Body / its: getCriteriaNamesListResponse/return/point '
in passing t.tmp_xml
varchar2 columns (30) the point road '.'
) x ;
or you can also go back to the old method (now obsolete in Oracle 11 and following):
SQL > select extractvalue (value (x), 'point') as element
tmp_table 2 t
3, table)
4 xmlsequence)
5. extract)

ORA-01861: literal does not match the format string
Hello
First of all, let's check the manual for the DEFAULT clause:
Function SQL/XML XMLTABLE in Oracle XML DB
The optional parameter
DEFAULTclause specifies the value to use when thePATHexpression results in an empty sequence (orNULL). Hisexpris an XQuery expression that is evaluated to produce the default value.According to the documentation, the DEFAULT clause must specify an XQuery expression.
However, is false, the implementation only expects an expression that matches a string, the content is not interpreted.
Bottom line is, if we specify directly a string, the expression is implicitly converted into one, and everyone knows how things can go when implicit conversions appear, especially when the dates or timestamps are involved.
Now let's focus on the impact of the DEFAULT clause on the evaluation of the query.
When a DEFAULT clause is specified, Oracle has rewritten projection differently and does not use the native format of XS: DateTime to convert the value:
Select x.*
Of
XMLTable ('/ DOC' from xmltype ('))
- 2013-08-14 T 15: 08:31
DT of COLUMNS by default systimestamp timestamp
) x
becomes:
SELECT THE EXISTSNODE (VALUE(KOKBF$), '/ DOC/DT')
WHEN 1 THEN LAUNCH (TO_TIMESTAMP (SYS_XQ_UPKXML2SQL (SYS_XQEXVAL (SYS_XQEXTRACT (VALUE(KOKBF$), '/ DOC/DT')), 50.1, 2)() as a timestamp)
ELSE CAST (TO_TIMESTAMP (TO_CHAR (SYSTIMESTAMP (6)), 'SYYYY-MM-DD "T" HH24:MI:SSXFF') AS timestamp)
END "DT".
TABLE ("SYS". "XQSEQUENCE"(EXTRACT ("SYS"." XMLTYPE"(")
- 2013-08-14 T 15: 08:31
See the red part: it does not use the format parameter, the conversion depends on NLS session parameters.
When there is no DEFAULT clause, the TO_TIMESTAMP function uses an explicit format:
Select x.*
Of
XMLTable ('/ DOC' from xmltype ('))
- 2013-08-14 T 15: 08:31
Dt timestamp - default systimestamp COLUMNS
) x
rewritten to:
SELECT CAST)
TO_TIMESTAMP)
SYS_XQ_UPKXML2SQL (SYS_XQEXVAL (SYS_XQEXTRACT (VALUE(KOKBF$), '/ DOC/DT'), 0,0,20971520, 0), 50.1, 2)
"SYYYY-MM-DD"T"HH24:MI:SSXFF"
)
BY timestamp - default systimestamp
) "DT".
TABLE ("SYS". "XQSEQUENCE"(EXTRACT ("SYS"." XMLTYPE"(")
- 2013-08-14 T 15: 08:31
So yes, maybe there is a bug here.
Edit: somewhat more followed.
It works:
Select x.*
Of
XMLTable ('/ DOC' from xmltype ("
")) Date of the dt of COLUMNS by default sysdate) x;
Actually no, it does not work. Certainly, maybe it produces no error, but the result is incorrect.
As explained, the conversion is based on the NLS (NLS_DATE_FORMAT in this case) session:
SQL > show nls_date_format settings
VALUE OF TYPE NAME
------------------------------------ ----------- ------------------------------
string of NLS_DATE_FORMAT JJ/MM/RR
SQL >
SQL > select sysdate to double;
SYSDATE
--------
16/08/13
SQL > select x.*
2 from
3 xmltable ('/ DOC' passing xmltype ("
")) 4 COLUMNS dt date default sysdate) x;
DT
--------
13/08/16
Oracle first converts SYSDATE to a string using current NLS_DATE_FORMAT, having for result Aug 16, 13 '
Then this string is converted to a DATE as XS: date is 'YYYY-MM-DD' leading 13/08/16 (13 August, 0016) which is incorrect.
The obvious solution to this problem is to control how Oracle converts implicitly string to timestamp format:
SQL > alter session set NLS_TIMESTAMP_FORMAT = "YYYY-MM-DD"T"HH24:MI:SS."
Modified session.
SQL > select x.*
2 from
3 xmltable ('/ DOC' from xmltype ('))
- 2013-08-14 T 15: 08:31
4 dt of systimestamp default timestamp COLUMNS
(5) x;
DT
---------------------------------------------------------------------------
2013-08-14 T 15: 08:31
SQL > select x.*

3 xmltable ('/ DOC' passing xmltype ("

By default systimestamp timestamp COLUMNS DT) x

XMLTable performance vs TABLE (XMLSequence ())
Hello world
I encountered a problem which I hope I can find help with.
He has a task to analyze a large XML text (~ 15 MB) and update a table based on it. So I created a procedure that takes a parameter of XMLType and does the job. Pretty simple. However, the thing is that if I use XMLTable, which is the preferred method to parse the XML, it runs for hours. Once I replace XMLTable with the method TABLE (XMLSequence ()), the procedure ends in less than two minutes on the same machine. Seems very strange to me.
Any ideas what could be the cause of such a poor performance from XMLTable?
Oracle version is 11.2.0.2.0

I'm interested to see the moment of execution.
Now if you want it to run faster, then
CREATE TABLE xml_hold (xml_col xmltype); -- can be a global temporary table if you desireand in your code
INSERT INTO xml_hold VALUES (p_points);then change select it above to
from xml_hold xh xmltable('/document/directory/reply[@type=''Points'']/data/row' passing xh.xml_colThis works because the default storage for XMLType columns in 11.2.0.2 was replaced by SECUREFILE XML BINARY. When you store XML in this column, Oracle preprocesses the XML file and stores the data in a binary format that is more effective to deal with. You can read about that in the Oracle documentation if you wish. Even with the charge to convert the XML into an internal format, the whole processing time should be faster given the application can now run much more efficiently.

create table prod_xml_tab (demo_field xmltype); insert into prod_xml_tab values(' <Product type="Laptop"> <Notebook Brand="HP" Model="Pavilion dv6-3132TX Notebook"> <Harddisk>640 GB</Harddisk> <Processor>Intel Core i7</Processor> <RAM>4 GB</RAM> <Price>1189</Price> <Display Type="LED" MonitorSize="15.6"/> <Weight>4.14</Weight> </Notebook> <Notebook Brand="HP" Model="HP Pavilion dv6-3032TX Notebook"> <Harddisk>640 GB</Harddisk> <Processor>Intel Core i7</Processor> <RAM>6 GB</RAM> <Price>1104</Price> <Display Type="LED" MonitorSize="15.6"/> <Weight>4.1</Weight> </Notebook> <Notebook Brand="HP" Model="Pavilion dv6-3079TX Notebook"> <Harddisk>500 GB</Harddisk> <Processor>Intel Core i7</Processor> <RAM>4 GB</RAM> <Price>1099</Price> <Display Type="LED" MonitorSize="15.6"/> <Weight>4.14</Weight> </Notebook> </Product>'); insert into prod_xml_tab values(' <Product> <Notebook Brand="Toshiba" Model="Satellite A660/07R 3D Notebook"> <Harddisk>640 GB</Harddisk> <Processor>Intel Core i7</Processor> <RAM>4 GB</RAM> <Price>1444</Price> <Display Type="LED" MonitorSize="15.6"/> <Weight>4.88</Weight> </Notebook> </Product>');943276 wrote:
for example, if the first row not contained that single product/Notebook (as the second row) there is need to use TABLE (XMLSEQUENCE...), right? Only extractvalue (demo_field, "Product/Notebook/@Brand") would suffice, right? xmlsequence is necessary because the first line has several entrances laptop and all these multiple information is always returned as a bunch of items for laptop (knots?) instead of relational lines, is that correct? then xmlsequence comes into play in order to convert every book of this bunch of laptops in topics separated more later converted into relational lines by SCOREBOARD operator. is it more correct?Thank you
Yep, that sounds about right.
With XMLTABLE, it would be something like this...

extraction of XML with xmltable
Because I recently received a comment here on OTN that extract/extractvalue should no more be used to extract the XML I was playing with xmltable.
However, I use a little problem.
I am trying to extract a very simple piece of xml in this way:
and I get this error: XPTY0004 - dynamic XQuery type mismatch: expected - singleton sequence got several sequence elementSELECT d.* FROM (SELECT xmltype ('<ArrayOfstring> <string>415391</string> <string>415392</string> </ArrayOfstring> ') x FROM DUAL), XMLTABLE ('$d/ArrayOfstring' PASSING x AS "d" COLUMNS string VARCHAR2 (100) PATH 'string') d;
I do not understand what goes wrong, since the same code work with a more complex pieve of XML:
Published by: Erik_NL on July 20, 2012 06:11SELECT d.* FROM (SELECT xmltype ('<ArrayOfProperties> <Properties> <Id>98247</Id> <code>001</code> <name>4 Megapixel</name> </Properties> <Properties> <Id>98248</Id> <code>001</code> <name>5 Megapixel</name> </Properties> </ArrayOfProperties>') x FROM DUAL), XMLTABLE ( '$d/ArrayOfProperties/Properties' PASSING x AS "d" COLUMNS Id VARCHAR2 (100) PATH 'Id', Naam VARCHAR2 (4000) PATH 'name', code VARCHAR2 (100) PATH 'code') dYou have two elements of the chain at the same level.
So, something like:
SQL> SELECT d.* 2 FROM (SELECT xmltype ('3 ') 6 x 7 FROM DUAL), 8 XMLTABLE ('$d/ArrayOfstring/string' 9 PASSING x AS "d" 10 COLUMNS string VARCHAR2 (100) PATH '/string') d; STRING ------------------------------------------------------------------------------ 415391 415392 SQL>415391 4415392 5 -

UNDERSTANDING
---------------------------
As my Xpath only points until the node - ParentPicklistValue and not the child nodes under it. That's why, when I try to interview the child nodes - / ParentPicklistValue/ListOfPicklistValue/PicklistValue/Code, I get the error mentioned above.
REQUIREMENT
-----------------------
Can someone help me to receive the values of the mother and child values based on xml and query above.Hello
It's a classic ;)
You need a second XMLSequence who shreds the collection of PicklistValue in relational lines:
select extractvalue(value(sr2), '/PicklistValue/Code', 'xmlns="urn:/crmondemand/xml/picklist"') AS Display , extractvalue(value(sr2), '/PicklistValue/DisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS Return , extractvalue(value(sr1), '/ParentPicklistValue/ParentDisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS parent_display , extractvalue(value(sr1), '/ParentPicklistValue/ParentCode', 'xmlns="urn:/crmondemand/xml/picklist"') AS parent_return from table( xmlsequence( extract( WEB_SERVICE( ... ) , '/soap:Envelope/soap:Body/ns:PicklistWS_GetPicklistValues_Output/ListOfParentPicklistValue/ParentPicklistValue' , 'xmlns="urn:/crmondemand/xml/picklist" xmlns:ns="urn:crmondemand/ws/picklist/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' ) ) ) sr1 , table( xmlsequence( extract( value(sr1) , '/ParentPicklistValue/ListOfPicklistValue/PicklistValue' , 'xmlns="urn:/crmondemand/xml/picklist"' ) ) ) sr2 ;What is your version of the database BTW?
10.2 and upward, you can use the XMLTable. -

A few comments:
(1) forget the extractvalue() function, it is discouraged in your version. Oracle recommends using the XQuery XMLQuery() and XMLTable() functions now.
(2) I see you try to work on the content provided by the operator PIVOT XML, but as always, unless you know the number of columns expected in advanceyou can have any output in relational format by using a simple SELECT statement. You can do this with ODCI but I don't think you want to go this way.
So basically what follows, but it clearly defeated the purpose of using a PivotChart in the first place:
SQL> select t.job_request_id, x.* 2 from mytab t 3 , xmltable( 4 '/PivotSet' 5 passing t.job_parameter_id_xml 6 columns "1000" number path 'item[column[1]="1000"]/column[2]' 7 , "1001" number path 'item[column[1]="1001"]/column[2]' 8 , "1007" number path 'item[column[1]="1007"]/column[2]' 9 , "1008" number path 'item[column[1]="1008"]/column[2]' 10 ) x 11 ; JOB_REQUEST_ID 1000 1001 1007 1008 --------------------------------------- ---------- ---------- ---------- ---------- 858554 208844 165972 3 1580 858555 261015 189185 3 25If you are looking for a text output only, it's another story like this boils down to the aggregation of the chain, but once again this could be done more simply without resorting to format XML PIVOT.
A quick attempt using an tab separator:SQL> select 'JOB_REQUEST_ID' || chr(9) || 2 xmlcast( 3 xmlquery('let $sep := codepoints-to-string(9) 4 return string-join(/PivotSet/item/column[@name="JOB_PARAMETER_ID"], $sep)' 5 passing JOB_PARAMETER_ID_XML 6 returning content) 7 as varchar2(4000) 8 ) as report 9 from mytab 10 where rownum = 1 11 union all 12 select to_char(job_request_id) || chr(9) || 13 xmlcast( 14 xmlquery('let $sep := codepoints-to-string(9) 15 return string-join(/PivotSet/item/column[@name="VALUE_TX"], $sep)' 16 passing JOB_PARAMETER_ID_XML 17 returning content) 18 as varchar2(4000) 19 ) 20 from mytab 21 ; REPORT -------------------------------------------------------------------------------- JOB_REQUEST_ID 1000 1001 1007 1008 858554 208844 165972 3 1580 858555 261015 189185 3 25 -

That's what you want:
select extractvalue(x.column_value, '/part/partNumber') as PARTNO, extractvalue(x.column_value, '/part/NSCM') as NCSM, extractvalue(x.column_value, '/part/LCN') as LCN, extractvalue(x.column_value, '/part/zone') as PZONE from imp_xml_file t , table( xmlsequence( extract(t.xml_xml, '/aircraft/brochure/part')) ) x where id = p_id ;What is your version of the database? (select * from version$ v)
From 10.2, XMLTable can do the same and much more.I'm XML file I have loaded like a BLOB, then converted into a XML_TYPE and converted into a CLOB
Once again, depending on your version, you can load your file directly into the table with an INSERT.

I get the following error...
ERROR on line 1:
ORA-01400: cannot insert NULL into (USER_CMNT. USER_CMNT_ID)
When I just run the select query to see the data I don't see no user_cmnt_id with a NULL value.
Please notify.Hello
You must apply the function extractValue on the XML fragment extracted with XMLSequence, not on the original document:
SELECT extractvalue (x.column_value,'/ROW/USER_CMNT_ID'), extractvalue (x.column_value,'/ROW/OPERATOR_ID'), extractvalue (x.column_value,'/ROW/CMNT_TEXT'), extractvalue (x.column_value,'/ROW/CMNT_DTMS') FROM gt_xmltype_tab gt, TABLE( XMLSequence( extract(gt.xmlfile1, '/ROWSET/ROW') ) ) x ;If you're on 10.2 or upward, prefer XMLTable:
SELECT x.user_cmnt_id , x.operator_id , x.cmnt_text , to_date(x.cmnt_dtms,'DD-MON-RR','nls_date_language=english') as cmnt_dtms FROM gt_xmltype_tab gt, XMLTable( '/ROWSET/ROW' passing gt.xmlfile1 columns user_cmnt_id number path 'USER_CMNT_ID' , operator_id varchar2(3) path 'OPERATOR_ID' , cmnt_text varchar2(120) path 'CMNT_TEXT' , cmnt_dtms varchar2(30) path 'CMNT_DTMS' ) x ;Published by: odie_63 on May 5, 2011 22:41

ExtractValue element node by using a variable
Hello
I have the following select statement, and it works fine.
SELECT extractvalue (ISBN_PAYLOAD, ' / ISBNdb/BookList/BookData/Subjects/Subject [1]') in Topic1
OF LIB_ISBN_T
WHERE LIB_ISBN_T_PK = 1;
It returns the first topic.
I would like crazy across all subjects, replacing the '1' by a numeric variable. I tried the following, and I receive blanks.
SELECT Topic1 extractvalue (ISBN_PAYLOAD, '/ ISBNdb/BookList/BookData/Subjects/Subject [(Current_Count)]')
OF LIB_ISBN_T
WHERE LIB_ISBN_T_PK = 1;
In a Select statement / Extractvalue statement, how can I replace the value inside the brackets with a variable?
Thank you very muchHello
You don't need to get a counter for it.
Here are two solutions depending on your version of the database, both based in break the XML in relational rows and columns:Pre-10 gr 2
SELECT extractValue(x.column_value, '/Subject') INTO v_subject FROM lib_isbn_t t, TABLE( XMLSequence( Extract( t.isbn_payload, '/ISBNdb/BookList/BookData/Subjects/Subject' ) ) ) x WHERE t.lib_isbn_t_pk = 1 ;10 gr 2 and +.
SELECT x.subject INTO v_subject FROM lib_isbn_t t, XMLTable( '/ISBNdb/BookList/BookData/Subjects/Subject' passing t.isbn_payload columns subject varchar2(30) path '.' ) x WHERE t.lib_isbn_t_pk = 1 ; -
Hello!
I need assistance with XMLTable instead of XMLSequence.
It's the part of my XML.
I have this statement that works very well, it returns under the data within the Group of idDocAntPap and its owner.<emiDocAnt> <owner>11111111111111</owner> <idDocAnt> <idDocAntPap> <tpDoc>01</tpDoc> </idDocAntPap> <idDocAntPap> <tpDoc>02</tpDoc> </idDocAntPap> </idDocAnt> <idDocAnt> <idDocAntPap> <tpDoc>03</tpDoc> </idDocAntPap> <idDocAntPap> <tpDoc>04</tpDoc> </idDocAntPap> </idDocAnt> </emiDocAnt> <emiDocAnt> <owner>22222222222222</owner> <idDocAnt> <idDocAntPap> <tpDoc>05</tpDoc> </idDocAntPap> <idDocAntPap> <tpDoc>06</tpDoc> </idDocAntPap> </idDocAnt> </emiDocAnt>
But I would use XMLTable instead of XMLSequence. The problem is: How can I get the value of "owner"?SELECT EXTRACTVALUE(VALUE(vw),'/emiDocAnt/owner'), EXTRACTVALUE(VALUE(vw3), '/idDocAntPap/tpDoc') FROM tb_projCargaTMP, TABLE(XMLSequence(EXTRACT(XMLAutorizacao,'/emiDocAnt'))) vw, TABLE(XMLSequence(EXTRACT(vw.column_value,'//idDocAnt'))) vw2, TABLE(XMLSequence(EXTRACT(vw2.column_value,'//idDocAntPap'))) vw3;
Thank you!!!SELECT vw."owner", vw."tpDoc" FROM tb_projCargaTMP, XMLTABLE('/emiDocAnt/idDocAnt/idDocAntPap' PASSING tb_CargaTMP.XMLAutorizacao COLUMNS "owner" NUMBER(14) PATH ???, <-- How can I get the owner value? "tpDoc" NUMBER(2) PATH '/idDocAntPap/tpDoc', "serie" VARCHAR2(3) PATH '/idDocAntPap/serie', "subserie" VARCHAR2(2) PATH '/idDocAntPap/subser', "nDoc" NUMBER(20) PATH '/idDocAntPap/nDoc', "dEmi" DATE PATH '/idDocAntPap/dEmi' ) vw;Based on a similar question to {message identifier: = 4093475}, you have two options, depending on whether you want to use XQuery or not within XMLTable.
WITH tb_projCargaTMP AS (SELECT XMLTYPE('11111111111111 01 02 03 04 22222222222222 05 06 and
SELECT vw.* FROM tb_projCargaTMP, XMLTable('for $i in /root/emiDocAnt/idDocAnt/idDocAntPap return element r{$i/../../owner, $i/tpDoc, $i/serie}' -- continue on PASSING tb_projCargaTMP.XMLAutorizacao COLUMNS owner NUMBER(14) PATH 'owner', tpDoc NUMBER(2) PATH 'tpDoc', serie VARCHAR2(3) PATH 'serie', subserie VARCHAR2(2) PATH 'subser', nDoc NUMBER(20) PATH 'nDoc', dEmi DATE PATH 'dEmi') vw;
