View on XmlType

I am trying to create a view that flattens certain parts of a chunk of XML in Oracle 9i r2, e.g.
create view cdp ("PNO") as
select xmltype.extract(
datapoint,
'/*/data:PNO/text()',
'xmlns:data="urn:acq-osd-mil:damir:data"').
getstringval() from incomingdatapoint
This works fine, except when attempting to use a group by on the "PNO" column of the view I get an ORA-22806.
Interestingly, querying the original table and grouping by the whole xmltype.extract expression works fine, so I don't see why it shouldn't work through a view as well.
Is there any way to get around this limitation? Any information would be appreciated. Thanks.

You added a targetNamespace to the XML Schema, changing the namespace for the elements. You need to define a namespace prefix mapping in each operator that uses a path expression... eg
SELECT X.id_exemp_req id_exemp_req
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/ExemptionRequestNbr','xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges") ExemptionRequestNbr_RInf
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/SIFCode','xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges",'xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges") SIFCode_RInf
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/DateRegistration','xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges") DateRegistration_RInf
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/DateRegistered','xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges") DateRegistered_RInf
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/RelationCode','xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges") RelationCode_RInf
FROM XML_EXEMPTION_REQUESTS_ALL X,
TABLE (xmlsequence(extract(XMLTYPE.createXML(X.xmlval),'/ExemptionRequest','xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges"))) tThe reason for this is that in the case of a schema based XMLType table or column, if there is no namespace:prefix mappings supplied we assume that the default namespace is the targetNamespace, avoiding the need to supply a namespace prefix mapping for the targetNamespace . This was probably a mistake, but it is quite useful.
In the case of a non schema based xmltype (which this is since it has been constructed from a CLOB we cannot make the assumption.
In general I would recommend that you change both views and provide an explicit namespace:prefix mapping to all the operators.

Materialized view with xmltype data type

Hello to all,
I have a challenge with my 10g r2 database. I need to make a materialized view from a table in this format:
Name Null? Type
RECID NOT NULL VARCHAR2(200)
XMLRECORD XMLTYPE
,my problem is that (as i read from docs) i cant make the view refreshable on commit and also i cant refresh the mv in fast mode ( i dont need to refresh mv complete - takes too long).
Do you have a hint for this?
Thank you in advance.
Daniel

hi,
I cant upgrade to 11g.Also i cant change the table structure.
Here is a sample of xmltype field content:
RECID XMLRECORD
D00009999 <row id='D100009999'><c2>10000</c2><c3>xxxxx</c3><c5>xxxx..
And i need to extract in the mv the data from c2, c3 and so on.
Still waiting for a hint.
Thank you.

View on xmltype column

Hi,
I had an xmlschema that looked as follows:
<xs:schema xmlns:ora="http://xmlns.oracle.com/xdb" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="unqualified" attributeFormDefault="unqualified">
     <xs:include schemaLocation="http://helios:8081/home/CVB/xsd/Elements.xsd"/>
And I read the following xml in the database:
<ExemptionRequest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges http://helios:8081/home/CVB/xsd/B303_Exemption.xsd">
     <ExemptionRequestInfo>
          <ExemptionRequestNbr>C061251532341</ExemptionRequestNbr>
          <SIFCode>016</SIFCode>
This xml-file was read into an clob column and on this clob column I made a relational view as follows:
SELECT X.id_exemp_req id_exemp_req
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/ExemptionRequestNbr') ExemptionRequestNbr_RInf
, extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/SIFCode') SIFCode_RInf
,     extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/DateRegistration') DateRegistration_RInf
,     extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/DateRegistered') DateRegistered_RInf
,     extractValue(value(t),'/ExemptionRequest/ExemptionRequestInfo/RelationCode') RelationCode_RInf
FROM XML_EXEMPTION_REQUESTS_ALL X,
TABLE (xmlsequence(extract(XMLTYPE.createXML(X.xmlval),'/ExemptionRequest'))) t
And this worked very well.
Now however, I have changed the schema as follows:
<xs:schema xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges" xmlns:ora="http://xmlns.oracle.com/xdb" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges" elementFormDefault="qualified" attributeFormDefault="unqualified">
     <xs:include schemaLocation="http://helios:8081/home/CVB/xsd/Elements.xsd"/>
The xml then looks as follows:
<ExemptionRequest xmlns="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.rsvz-inasti.fgov.be/schemas/B2B/Exchanges http://helios:8081/home/CVB/xsd/B303_Exemption.xsd">
But now my view doesn't work anymore. The relational columns are all empty.
But I only changed the header of the schema and not the structure/content of it.
I have another view which works directly on the XMLTYPE TABLE (and that has the same structure) and this still works fine:
SELECT extractValue(value(u),'/ExemptionRequestInfo/ExemptionRequestNbr') ExemptionRequestNbr_RInf
, extractValue(value(u),'/ExemptionRequestInfo/SIFCode') SIFCode_RInf
,     extractValue(value(u),'/ExemptionRequestInfo/DateRegistration') DateRegistration_RInf
,     extractValue(value(u),'/ExemptionRequestInfo/DateRegistered') DateRegistered_RInf
,     extractValue(value(u),'/ExemptionRequestInfo/RelationCode') RelationCode_RInf
,     extractValue(value(v),'/ExemptionSelfEmployed/INSS') INSS_SE
FROM XML_EXEMPTION_REQUESTS X,
TABLE (xmlsequence(extract(value(X),'/ExemptionRequest'))) t,
     TABLE (xmlsequence(extract(value(t),'/ExemptionRequest/ExemptionRequestInfo'))) u,
     TABLE (xmlsequence(extract(value(t),'/ExemptionRequest/ExemptionSelfEmployed'))) v,
     TABLE (xmlsequence(extract(value(v),'/ExemptionSelfEmployed/LegalInfo'))) w
Does anybody know why this happens?
Thanks in advance,
Geert

Read-only view for XMLType data

HI Gentlemen,
When I execute my SQL statement:
select extract(object_value,'/keytabs/keytab/@SN') SN from keytabs
against a schema-based XMLType table from SQL*Plus I get normal response:
EXTRACT(OBJECT_VALUE,'/KEYTABS/KEYTAB/@SN')
S_KBV_GESCHLECHT
S_VDX_KONTENART
However, when I create a Fusion application with business components, and a custom view in the Model project with the SQL statement above,
it yields:
oracle.sql.OPAQUE@1623820.
Attribute type is String, and query column is VARCHAR(255). There is no entity because the view is read-only.
Can anyone help me how to directly query XMLType to display the contents?
Thanks, regards
Miklos HERBOLY

Can you try:
select cast(extract(object_value, '/keytabs/keytab/@SN') as varchar2(255)) SN
from keytabsJohn

How to install an external editor in version 2.1.1.64 for viewing XMLType

I have a question about viewing XMLType in version 2.1.1.64
If you want to view the content of an XMLType column in a data-tab, you can double click on the particular XMLType field and the edit button appears at the end. Push this edit button and an "Edit Dialog" popup appears with the data presented as one line.
Push the External Editor button and you get a dialog that informs you about the not supported mime type of the selected object. You can find the complete list of supported mime types in Tools->Preferences->External Editor panel. I like to use an external XML editor for viewing an xmltype column, can anyone put me on the right track? Change the Editor Location for the .xml file extension didn`t work.
Kind regards,
Erwin Snippert

This is the case:
SQL Developer version 2.1.1.64
Oracle client 11gR2
Oracle Database 9.2.0.6.
Under the table tree, on the left side of the screen, a table is selected with 3 columns. One of them is a XMLType column.
Click on the data tab on the right side of the screen and a part of the xml-data is visible of that XMLType column.
Perhaps my expectations are too high, i want to see the all XML data in a structured and readable way.
I have tried to accomplish this by double clicking on the particular data in the XMLType column. This results in an pencil icon on the right side of the data.
Click on this icon and a popup window appears with the 'Edit Value' titel. This windows shows the xml data as one string, not very readable.
I have the oppurtunity to click on an 'External Editor' button. It seems to me that i can use this button to see/edit the data with an external editor.
If you click on this button, a dialog appears with the following message : 'The Mime Type of selected object is currently not supported. Please see the complete list of supported Mime Type and extension in Tools>Preferences>External Editor panel.'
I have 2 questions, perhaps you can put me in the right direction :
- Why can't SQL developer standard display XML in a structured/readable way?
- How must SQL Developer be configured to use an external editor for displaying XML data from XMLType columns?
Kind Regards, Erwin

Oracle XML DB Using Views

I created a view for XMLType table. When I insert rows into table they are not reflected in view.
CREATE TABLE EMPLOYEE OF XMLType
XMLTYPE store AS OBJECT RELATIONAL
XMLSCHEMA "EMPLOYEE.XSD" ELEMENT "root";
CREATE OR REPLACE VIEW
employee_master_view(empid, empname, empproj, emporg)
AS SELECT extractValue(OBJECT_VALUE, '/EMPLOYEE/empid'),
          extractValue(OBJECT_VALUE, '/EMPLOYEE/empname'),
          extractValue(OBJECT_VALUE, '/EMPLOYEE/empproj'),
          extractValue(OBJECT_VALUE, '/EMPLOYEE/emporg')
     FROM EMPLOYEE;
INSERT INTO EMPLOYEE VALUES (XMLType(bfilename('XML_DIR', 'EMPLOYEE.XML'),
                                     nls_charset_id('AL32UTF8')));
SELECT object_value from employee;
OBJECT_VALUE
SYS.XMLTYPE
SELECT extract (object_value, '/') from employee;
EXTRACT(OBJECT_VALUE,'/')
<root><empid>1</empid><empname>Gates</empname><empproj>EIS</empproj><emporg>Tata Cosultancy Services</emporg></root>

4 rows selected
select empid, empname, empproj, emporg from employee_master_view;
EMPID     EMPNAME     EMPPROJ     EMPORG
1 rows selected
This returns empty rows. It should be printing the values of the xml tags in the columns.
Please help.

extractValue(OBJECT_VALUE, '/EMPLOYEE/empid'),
I don't see any "EMPLOYEE" element in your sample XML document. Do you?
Try this XPath instead : /root/empid
And be aware extractValue and alike are deprecated starting from 11.2.

XML FOREST Output as XMLTYPE

Hi ,
When I am using the Xml with many attributes for the tags creation it displays the output as xml type only. Is there a different way to read this output or there is any characters limitation for display because when I pass few attributes the output is as expected. The attributes passed are the table columns read from the underlying table.
Please help me in understanding the output of XML and how its output can be displayed to read as many attributes possible.
Thanks for your help.

What tool/version are you using to view the XMLType content?

Write XML file on client

I'm trying to generate XML files on a client machine. I'm using SQL*Plus Instant Client v 10.1.0.4.0 connected to DB version 10.1.0.3.0. I've created a view of XMLType and am able to select XML from this view. I've been unable to figure out a way to generate well-formed XML via a Spool command and Select statement as Sqlplus returns the XML as one row and has problems with line wrapping, embedded spaces, and also including the SQL command in the spooled output. I've tried many different permutations of Set commands to no avail.
Is there a way to generate a valid XML file from Sqlplus on a client machine using the Spool command? If not Sqlplus, any other suggestions?
Thanks,
Glenn

I would be inclined to write a pipelined function to take a clob, and break it up into pieces (perhaps after a '>').
Here's an example of a pipelined function, which you can modify to suit your needs, such as working with CLOBs. You may also want to add more intelligence to it, such as checking for when the chunk is longer than 2000 characters.
CREATE TYPE tvc2000 AS TABLE OF VARCHAR2(2000)
CREATE OR REPLACE
FUNCTION chopper
p_string IN VARCHAR2
RETURN tvc2000
PIPELINED
IS
l_len NUMBER := LENGTH(p_string);
l_out NUMBER := 0;
l_pos NUMBER;
BEGIN
l_pos := INSTR(p_string, '>', l_out+1);
WHILE l_pos > 0 LOOP
    PIPE ROW(SUBSTR(p_string, l_out+1, l_pos - l_out));
    l_out := l_pos;
    l_pos := INSTR(p_string, '>', l_out+1);
END LOOP;
IF l_out < l_len THEN
    PIPE ROW(SUBSTR(p_string, l_out+1, l_len - l_out));
END IF;
RETURN;
END;
SELECT *
FROM TABLE(chopper('abc>def>'))

DBMS_XMLDOM Package Sample

Hello everyone
I need to generate XML output through PL/SQL. Though I had been successful in using DBMS_XMLGEN package, I need to us DBMS_XMLDOM, as I need create hierarchical xml document (ie., Department .....Department Attributes; Employee ....employee attributes....Employee and its attributes within Department node). I was searching for any samples but could not find any. Any help would be appreciated. Also, if I need to approach it in a different way, please let me know about it.
Thank you in advance
VV.

There are some examples of using DBMS_XMLDOM in the online documentation ...
http://download-west.oracle.com/docs/cd/B14117_01/appdev.101/b10790/xdb10pls.htm#sthref1069
Some other options would be to use XMLType Views, the XMLType functions or schema object types and the object based XMLType constructor ...

Approach to parse large number of XML files into the relational table.

We are exploring the option of XML DB for processing a large number of files coming same day.
The objective is to parse the XML file and store in multiple relational tables. Once in relational table we do not care about the XML file.
The file can not be stored on the file server and need to be stored in a table before parsing due to security issues. A third party system will send the file and will store it in the XML DB.
File size can be between 1MB to 50MB and high performance is very much expected other wise the solution will be tossed.
Although we do not have XSD, the XML file is well structured. We are on 11g Release 2.
Based on the reading this is what my approach.
1. CREATE TABLE XML_DATA
(xml_col XMLTYPE)
XMLTYPE xml_col STORE AS SECUREFILE BINARY XML;
2. Third party will store the data in XML_DATA table.
3. Create XMLINDEX on the unique XML element
4. Create views on XMLTYPE
CREATE OR REPLACE FORCE VIEW V_XML_DATA(
Stype,
Mtype,
MNAME,
OIDT
AS
SELECT x."Stype",
x."Mtype",
x."Mname",
x."OIDT"
FROM data_table t,
XMLTABLE (
'/SectionMain'
PASSING t.data
COLUMNS Stype VARCHAR2 (30) PATH 'Stype',
Mtype VARCHAR2 (3) PATH 'Mtype',
MNAME VARCHAR2 (30) PATH 'MNAME',
OIDT VARCHAR2 (30) PATH 'OID') x;
5. Bulk load the parse data in the staging table based on the index column.
Please comment on the above approach any suggestion that can improve the performance.
Thanks

I was not aware of Virtual column but looks like we can use it and avoid creating views by just inserting directly into
the staging table using virtual column.
Suppose OID id is the unique identifier of each XML FILE and I created virtual column
CREATE TABLE po_Virtual OF XMLTYPE
XMLTYPE STORE AS BINARY XML
VIRTUAL COLUMNS
(OID_1 AS (XMLCAST(XMLQUERY('/SectionMain/OID'
PASSING OBJECT_VALUE RETURNING CONTENT)
AS VARCHAR2(30))));
1. My question is how then I will write this query by NOT USING COLMUN XML_COL
SELECT x."SECTIONTYPE",
x."MACHINETYPE",
x."MACHINENAME",
x."OIDT"
FROM po_Virtual t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col                          <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
MachineType VARCHAR2 (3) PATH 'MachineType',
MachineName VARCHAR2 (30) PATH 'MachineName',
OIDT VARCHAR2 (30) PATH 'OID') x;
2. Insetead of creating the view then Can I do
insert into STAGING_table_yyy ( col1 ,col2,col3,col4,
SELECT x."SECTIONTYPE",
x."MACHINETYPE",
x."MACHINENAME",
x."OIDT"
FROM xml_data t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col                         <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionType VARCHAR2 (30) PATH 'SectionType',
MachineType VARCHAR2 (3) PATH 'MachineType',
MachineName VARCHAR2 (30) PATH 'MachineName',
OIDT VARCHAR2 (30) PATH 'OID') x
where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
insert into STAGING_table_yyy ( col1 ,col2,col3
SELECT x."SectionOID",
x."EventName",
x."OIDT"
FROM xml_data t,
XMLTABLE (
'/SectionMain'
PASSING t.xml_col                         <--WHAT WILL PASSING HERE SINCE NO XML_COL
COLUMNS SectionOID PATH 'SectionOID',
EventName VARCHAR2 (30) PATH 'EventName',
OID VARCHAR2 (30) PATH 'OID',
) x
where oid_1 = '99dd48cf-fd1b-46cf-9983';<--VIRTUAL COLUMN
Same insert for other tables usind the OID_1 virtual coulmn
3. Finaly Once done how can I delete the XML document from XML.
If I am using virtual column then I beleive it will be easy
DELETE table po_Virtual where oid_1 = '99dd48cf-fd1b-46cf-9983';
But in case we can not use the Virtual column how we can delete the data
Thanks in advance

and create a synonym for the view on the local?it doesn't work !

alternatively,
what happens if you modify from person@oraclelink in
the create or replace view personne_oracle?it doesn't work !
The problem is the dblink ! Without it it's work !
thx for your answer.

How to create a relational view base on an xmltype table which included sev

Hi,
I am using oracle 11.2.0.1.0.
how to create a relational view base on an xmltype table which content several different .xml files?
Thanks.
for examle:
SQL> SELECT OBJECT_VALUE FROM document;
Edited by: Cow on Jan 6, 2011 7:57 PM

For example I already have these three xml files inserted into the document xmltype table.
These xml files have same schemas. I have attached below.
I want to show all elements/attribute values in xml files to relational view.
Is this possible to create one big relational view to show everything
or I have to create three separate relation views then use UNION to put together? Thanks a lot. Cow

Inserting into XMLType View

I have created an XMLType view with an INSTEAD OF trigger to insert data into the underlying tables. I used your example on XMLType view of Relational Content
It works great if I have no attributes defined in the root element of the XML document (i.e. xmlns, schemaLocation, etc.). However, if my document contains any of those attributes, it will not load. I have tried creating the view with and without the xml attributes, as well as making sure that the schemaLocation is identical to the one in the document (copied and pasted just to make sure).
Is there anything that you can point to right away that I'm missing?
If needed, I can post code for you.
Thanks!

Here is the code I used to generate the tables, view, and triggers:
drop table p_student_demographics;
create table p_student_demographics -- a
wiser_id varchar2(8),
first_name varchar2(15),
middle_name varchar2(15),

drop table p_scorer_info;
create table p_scorer_info -- b

scorer_number number,

email varchar2(50)
drop table p_test_record;
create table p_test_record -- c
wiser_id varchar2(8),
test_record_id number,
grade_tested varchar2(2),
first_scorer_completed varchar2(3),
second_scorer_completed varchar2(3)
drop table p_psw_test_results;
create table p_psw_test_results -- d
test_record_id number,
subject varchar2(7),
entry_number number,

Insert statement:
insert into paws_alt_test_results values (xmltype(bfilename('XMLDIR','test-paws-alt.xml'),nls_charset_id('AL32UTF8')));
There are no errors shown on the insert statement. It tells me that one row was inserted, but there is no data when looking at the tables (unless I remove the attributes from the root element of the XML file).
I'm using version 10.2.0.3
Thanks for your help!
