XMLCast, XMLQuery vs extractValue
Hello fellows, newbie question - I am unable to find a working example to extract the values using the XMLQuery/XMLCast to replace the obsolete extractValueHere is an XMLTYPE containing
< CalculateFITResponse xmlns = "http://tempuri.org/" >

This function-

(successfully I might add)
How to rewrite the function by using the XMLQuery and XMLCast?

It's hard to believe...
I found this one in less than a minute in the documentation:

And the forum is full of examples too, just use has research with XMLCast + XMLQuery, namespace keywords.

using XPath with SQL to extract XML data
Given the data like this:
I usually use extractValue as shown below, for example function to extract the value for the last parameter in the above data, for example:<?xml version="1.0"?> <ExtendedData> <Parameter name="CALLHOLD"><BooleanValue>true</BooleanValue></Parameter> <Parameter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="BARRING_PASSWORD" xsi:nil="true"/> <Parameter name="ALLCF"><BooleanValue>true</BooleanValue></Parameter> <Parameter name="RealProv"><BooleanValue>false</BooleanValue></Parameter> </ExtendedData>
Any ideas on how can I return the value of the parameter xsi: Nil for that node:select extractValue(extended_data,'/ExtendedData/Parameter[@name="RealProv"]/BooleanValue') "my_column_alias" from table
I would like to extract the<Parameter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="BARRING_PASSWORD" xsi:nil="true"/>
intrue

Retrieve / search a specific node of the XML file
Hello
I have a question about reading the XML (search) in PL SQL file:
There is an XML file with the following structure:
How it is possible to filter a node by one of its attribute value. For example:<root> <Hnode1 attr1="value1" /> <Hnode2 attr1="value1" /> <node1_of_Hnode2 id="10" personname="Steven"/> <node2_of_Hnode2 id="20" personname="Christian"/> <node3_of_Hnode2 id="30" personname="Arnold"/> . . <Hnode2/> <root/>
The id of a person - I guess that id = 20. In this case I would like to get the whole node (in this case node2_of_Hnode2) to get the personname = > 'Christian '.
Just like a SELECT statement (WHERE ID = 20)
Is it possible to get it in a single order or should it be buckled on all the lines in the Document. Can you please provide an example for me.
Thank you for advice!The basic version is 10.
Sorry, this is not a version.
For example:SQL> select * from v$version; BANNER ---------------------------------------------------------------- Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi PL/SQL Release 10.2.0.5.0 - Production CORE 10.2.0.5.0 Production TNS for 64-bit Windows: Version 10.2.0.5.0 - Production NLSRTL Version 10.2.0.5.0 - ProductionThe use of the extraction of the values?
1. better in a Select statement. assignment directli in a variable, or by using the xmlquery function?PL/SQL or SQL calls to the XMLType methods such as getStringVal() or extract() function should be equivalent (save the change of context).
However, none of them are the right way to retrieve a scalar value of a given node.
You must use the rather extractValue() function (SQL only) for immediate release< 11.2="" and="" xmlcast/xmlquery="" starting="" with="">Another Question:
I've seen a lot of options for dealing with XML files.
In my case only query data in XML files is relevant.
I've seen to many API called XMLDOM, DMBS_XMLDOM, XMLTYPE...
When to use these APIs. Can you give me feedback on this please?
It is a broad topic.
An appropriate response will depend on your condition.-You have to deal with large files and if so what size?
-Performance/memory management is a concern for you?
-You want to extract unique values or process the XML content in the form of relational data?If you have any specific test cases to show us, please post in the {forum: id = 34} forum and make sure to include all the necessary details (see the FAQ).

Cannot retrieve the data by binary storage by default for XML 11 g
Oracle 11.2
All,
As someone mentioned in another post, I got I should use binary XMLType CLOB rather than 11g because it is more efficient. When I create the XMLType column as binary I can't retrieve the value of the column, but when I use CLOB I am able to extract data on.
-Create table with XMLTYPE column. Since it is 11.2 storage of the column is automatically binary
CREATE THE TABLE HR. XMLTABLESTORE (key_id VARCHAR2 (10) PRIMARY KEY, xmlloaddate date, xml_column XMLTYPE);
-Insert the XML into the XML column
INSERT INTO HUMAN RESOURCES. VALUES XMLTABLESTORE (HR. XMLSEQUENCE. NEXTVAL, SYSDATE, XMLType (bfilename ('XMLDIRX', 'PROD_20110725_211550427_220b.xml'),
nls_charset_id ('AL32UTF8'))); COMMIT;
-When I do a select I see full XML in the xml_column column
SELECT * FROM HR. XMLTABLESTORE
-When I run the following query I get the following:
SELECT extract (xml_column, ' / / MapItem/@ProductNum') ProductNum OF HR. XMLTABLESTORE
ProductNum
-------------
XMLType
-When I run the following query on the @, I get the following:
SELECT extract (xml_column, ' / / MapItem/ProductNum ') ProductNum OF HR. XMLTABLESTORE
ProductNum
-------------
Null value
When I run the same SELECT query retrieves (xml_column, ' / / MapItem/@ProductNum') ProductNum OF HR. XMLTABLESTORE and the table is created by CLOB, I get out the expected value of the XML file.
How can I get the query to retrieve the data through a binary file?
I appreciate any help in advance.
Thank you
Shawn

XML file too large or too large XML element
I try to import an xml file into the repository and have it shred in the object-relational tables. I signed up a diagram and it created types, triggers and object-relational xml_tables. The complete xml file is > 80 MB. XDB created all fields VARCHAR2 (4000).
error code when you import the complete XML file. That's what I need to fix in the end.
I guess that some fields have lengths > 4000 max. I intend to annotate the schema with SQLType = 'CLOB', but there are fields to change. I could copy the xml file and reduce this xml file to a record of any in the tables. My plan was to write a review on the bfile to get the lengths of some fields, annotate the .xsd with CLOB when needed and then import it again. To do this, I have a 1 imported in a table and as a bfile type recording file.DECLARE res BOOLEAN; BEGIN res := DBMS_XDB.createResource('/home/pharma/drugbank.xml', bfilename('XMLPHARMA', 'drugbank.xml'), nls_charset_id('AL32UTF8')); END; / COMMIT; XML file encounters errors on the import. An error was encountered performing the requested operation ORA-30951: Element or attribute at Xpath references exceeds maximum length ORA-06512 at "XDB.DBMS_XDB", line 315 ORA-06512 at line 4 30951.00000 - "Element or attribute at Xpath %x exceeds maximum length" *Cause: An attempt was made to insert a node of length exceeding the maximum length (specified by the maxLength facet) into an XML document. *Action: Do not attempt to add a node exceeding the maximum length to XML documents. Vendor code 30951Error at Line:18
Here is my code selection length in a generated object-relational table as a single folder.
Here's the code for the bfile. Same results, but using deprecated functions. I read the white paper, Oracle XML DB: best practices for optimal performance of queries XML. It is said that the function extract(), extractvalue(), Table (XMLSequence ()) and XMLType() are deprecated in 11 GR 2.CREATE OR REPLACE VIEW pharma.drugs_vw AS SELECT d.* FROM drugs, XMLTABLE ('/drugs' PASSING OBJECT_VALUE COLUMNS drugbank_id VARCHAR2(20) PATH 'drug/drugbank-id', name VARCHAR2(50) PATH 'drug/name', description VARCHAR2(4000) PATH 'drug/description' ) d / select max(length(drugbank_id)) as dbidlen, max(length(name)) as nmlen, max(length(description)) as desclen from drugs_vw; DBIDLEN NMLEN DESCLEN --------------- --------------- --------------- 7 9 229 1 row selected.
Is this better code to get the maximum length of a bfile type xml fields? Here's what I have so far. It works on a simple drugbank id.-- Note extractvalue is deprecated in 11gr2 replaced by W3C standard -- XMLCast(XMLQuery()) -- TABLE(XMLSequence) is replaced by XMLTable -- XMLType() is replaced by XMLParse() SELECT max(length(extractvalue(column_value, '/drug/drugbank-id'))) dbidlen, max(length(extractvalue(column_value, '/drug/name'))) nmlen, max(length(extractvalue(column_value, '/drug/description'))) desclen FROM TABLE(XMLSequence(XMLTYPE(bfilename('XMLPHARMA', 'db00001.xml'),nls_charset_id('AL32UTF8')).extract('/drugs/drug'))) d WHERE ROWNUM <= 5; DBIDLEN NMLEN DESCLEN --------------- --------------- --------------- 7 9 229
I try to run it on the full file and get this errorSELECT max(length(drugbank_id)) AS dbidlen, max(length(name)) AS nmlen, max(length(description)) AS desclen FROM (XMLTABLE('*' PASSING (XMLType(bfilename('XMLPHARMA', 'db00001.xml'),nls_charset_id('AL32UTF8'))) COLUMNS drugbank_id VARCHAR2(20) PATH 'drug/drugbank-id', name VARCHAR2(50) PATH 'drug/name', description VARCHAR2(4000) PATH 'drug/description' ) );

Thanks in advanceHello
You can use the extractValue() function.
Or, if you are using the version 11g, Oracle recommends to use XMLQuery() instead:DECLARE xmldoc xmltype := xmltype( 'Oracle -
problems with selection of XMLType column value
I want to extract my XMLType column values. Can someone tell me why this works
but it does not work?select XMLCAST ( XMLQUERY ( 'declare default element namespace "urn:hl7-org:v3"; (: :) declare namespace voc = "urn:hl7-org:v3/voc"; (: :) $doc/ClinicalDocument/recordTarget/patientRole/patient/name/family' passing CCD_DOC as "doc" returning content ) as VARCHAR2(4000) ) from CCD

I don't get any errors on the other, but the three XML derived columns are null. The values are not retrieved while the values ARE retrieved using the first method.
Thank you!XMLTable...

When I run some extractvalue (' CCD_DOC, ' recordTarget/patientRole/patient/name/family ") of the CCD; no error is returned, but also, I don't get the value. What Miss me?In a Word - namespace definitions...
Here is an example written using XMLQuery, rather than extractValue, which is the preferred approach in 10.2.x and later...

I have a table EMP that contains an xmltype column called empinfoCREATE TABLE EMP
(
DATE EVENT_DATE,
empinfo SYS. XMLTYPE
)
XMLTYPE XML STORE AS BINARY XML NAVIGATIONThis pass of xmltype contains xml unstructured documents. I am interested in indexing on 'empno '.
I am able to create an index, but it will be only works on the first level.
CREATE INDEX subset_xmlindex ON emp (empinfo)
indexType IS xdb.xmlindex
parameters ("PATHS (INCLUDE (//empno))
path table subset_pathtable (undesirable tablespace)');When I do the next xmlexists, he found all the empno, but it does not use the index.
XMLExists ('/ / * [empno = 171943270] ' from empinfo)
When I do that it finds the empno in the fitrst level and use the index. but it does not find the empno < empinfo > level.
and xmlexists ('/ person / * [empno = 1073630546]' from empinfo)
question: How can I use the index on all the elements 'empno' wherever they are in the doc.
is it still possible? the table contains millions of records.doc suggest using //empno in the index include the will of the index on the regradless of all the empno hence they are.
-xml1
< person >
< personrecord >
< name >
.....
< empno >
...
< / personrecord >
< / person >
-xml2
< person >
< personinfo >
< name >
....
< empinfo >
< empno >
....
< / empinfo >
....
< / personrecord >
< / person >Version database please?
And question: is there still a single node "empno" by the document?
The following works for me.
Make sure you pass the link as string variable, no number (unless you create an additional digital index on the VALUE of path):
SQL> select * 2 from emp 3 where xmlexists('//empno[.=$empno]' 4 passing empinfo 5 , '7777' as "empno" 6 ) 7 ; Execution Plan ---------------------------------------------------------- Plan hash value: 1962240707 ------------------------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | ------------------------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | 1 | 145 | 5 (20)| 00:00:01 | | 1 | NESTED LOOPS | | 1 | 145 | 5 (20)| 00:00:01 | | 2 | VIEW | VW_SQ_1 | 1 | 12 | 3 (0)| 00:00:01 | | 3 | HASH UNIQUE | | 1 | 47 | | | | 4 | NESTED LOOPS | | | | | | | 5 | NESTED LOOPS | | 1 | 47 | 3 (0)| 00:00:01 | | 6 | TABLE ACCESS BY INDEX ROWID| X$PT72R2I5S5V9A9VE0GOACG0GKWIG | 1 | 12 | 2 (0)| 00:00:01 | |* 7 | INDEX RANGE SCAN | X$PR72R2I5S5V9A9VE0GOACG0GKWIG | 1 | | 1 (0)| 00:00:01 | |* 8 | INDEX RANGE SCAN | SYS166546_SUBSET_XM_VALUE_IX | 7 | | 0 (0)| 00:00:01 | |* 9 | TABLE ACCESS BY INDEX ROWID | SYS166546_SUBSET_XM_PATH_TABLE | 1 | 35 | 1 (0)| 00:00:01 | | 10 | TABLE ACCESS BY USER ROWID | EMP | 1 | 133 | 1 (0)| 00:00:01 | ------------------------------------------------------------------------------------------------------------------- Predicate Information (identified by operation id): --------------------------------------------------- 7 - access(SYS_PATH_REVERSE("PATH")>=HEXTORAW('021FD8') AND SYS_PATH_REVERSE("PATH")Alternatively, if each doc contains at most one occurrence of 'empno', you can add a virtual column that retrieves and create an index on this column:

Need advice on how to analyze the integrated calculation
Hello
I have a following problem:
I have a table1 where I have the list of parameters to their current values;
I have a table2 where I have a list of calculations that use these input parameters; the formula is stored as a string in a field
I also have a table 3 where I have a list of calculations with the corresponding parameters, which are used by them;
I also have 4 table, which must contain the result of a calculation according to the formula of table2 with values of parameters from table1
requirement: procedure that will populate the table 4.
my original idea was to do the following:
1 call the procedure with the id of calculation
2 extract the list of parameters for calculating id
3 assign the values from table1 to the parameters of the step 2
4. run the formula with the assigned values-> new procedure called with the formula and table of variables/parameters? dynamic SQL?
can you please advise me what will be the best approach here?
Thank you for the advice

Retrieve the element of the SOAP response
Hello world
DB version 11.2.0.4
Tool: pl/sql developer
How can I retrieve the element of NfeLinkDanfe by using the xmlQuery? It is a SOAP response...
With this query, I can retrieve the node "SOAP - ENV:Body", but I Don t know how to get an attribute of the child:
Select (xmlcast)
XMLQUERY)
' declare namespace SOAP-ENV = "http://schemas.xmlsoap.org/soap/envelope/"; (:
declare namespace xx = "GXX_KB001_v2.1.0.0"; (:
/ SOAP-ENV:Envelope/SOAP-ENV:Body/WSRecepcaoNFe.ExecuteResponse'
from t.a.
contents of return
)
as varchar2 (100)

of tmp_xml t
It's the soap response:

Newbie on XMLTABLE XML DB!
example of XML (person_data.person_data):
<CstmrPmtStsRpt> <GrpHdr> <MsgId>99</MsgId> <CreDtTm>2013-11-12T08:10:57</CreDtTm> <InitgPty> <Id> <OrgId> <Othr> <Id>BANK_ID</Id> <SchmeNm> <Cd>BANK</Cd> </SchmeNm> </Othr> <Othr> <Id>CUST_ID</Id> <SchmeNm> <Cd>CUST</Cd> </SchmeNm> </Othr> </OrgId> </Id> </InitgPty> </GrpHdr> </CstmrPmtStsRpt>
I want to extract the Id associated with the BANK (and only the Bank Id):
Asked the SQL output:
BANK_IDSo far, I came with:
SELECT t.column_value FROM person_data a, XMLTABLE ( 'for $root in /CstmrPmtStsRpt/GrpHdr/InitgPty/Id/OrgId/Othr where $root/SchmeNm/Cd = "BANK" return $root/Id' passing a.person_data) t;
Which returns
< id > BANK_ID < /ID >
Add text() as below:
SELECT t.column_value FROM person_data a, XMLTABLE ( 'for $root in /CstmrPmtStsRpt/GrpHdr/InitgPty/Id/OrgId/Othr where $root/SchmeNm/Cd = "BANK" return $root/Id/text()' passing a.person_data) t;
Returns < no rows returned >
I know I'm missing something basic here - just need a pointer. Thank you!
Hello
I know I'm missing something fundamental here
No, you do not miss anything, what you have tried must have worked (even if it is not the usual way more to do).
He must have the bug.
Fortunately, the solution is quite simple, use an explicit projection via the COLUMNS or XMLQuery clause instead.
Examples:
SQL > create table person_data (doc xmltype);
Table created
SQL >
SQL > insert into person_data values)
2 xmltype (')
