Loading xml instances into repository

Hello,
I have successfully registered an xml schema document at the XML DB repository. A table had been created and the storage is object-relational.
Now I want to load XML instances of the registered schema into the repository using WebDAV or HTTP. How can I tell the repository that these XML documents are schema instances and that they should be rows of the created table?
Thanks in advance.
Lars Geldner

Lars,
Since no one else has answered this inquiry, I'll give you my opinion. You will need to add the namespace to the XML document when loading it into the repository. This way the XMLDB engine will know where the document needs to go to get shredded.
I've had trouble when using the drag and drop of WebDav to load up .xml docs into a registered schema. It was easier for me to use the directory entry pointer and load them up to the XMLDB that way. It may have been my expierence only though.

Error while loading XML files into scott user

Hi All,
I'm new to xml files. I need to load xml files into database through OWB.
I have xml file in my local machine & am trying to load into table PO of Scott. Scott is registered as repository user.
Followed same steps as specified in userguide.
But, when executing the procedure ( in two ways one as just table name, and other as user.table name) it is showing the below error:
Procedure is:(1)--with username.tablename
begin
wb_xml_load(
'<OWBXMLRuntime>'||

Note: Everything works fine if I create PO table in OWBSYS user and execute the procedurein OWBSYS user. OWBSYS.PO table will be loaded.
What privileges are missing, what shouldI do if I want to execute the procedure from scott user and load the table of scott.
Thanks in advance for the help.

Hi Joshna,
Please follow below steps to load xml file to oracle database.
1.First connect to owb (Design Center) through your repository owner user (ex : REP_OWNER).
2. Import WB_XML_LOAD procedure . and exit to repository owner.
3. connect to owb design center through your repository user (ex : REP_USER)
Create New mapping and drag one Constant Operator and create one attribute, paste / edit following code
'<OWBXMLRuntime>'||
'<XMLSource>'||
'<file>E:\SOURCE\emp.xml</file>'||
'</XMLSource>'||
'<targets>'||
'<target truncateFirst = "FALSE" dateFormat="yyyy.MM.dd">rep_user.emp</target>'||
'</targets>'||
'</OWBXMLRuntime>'
4. Drag pre mapping operator and select WB_XML_LOAD procedure
5. Connect Constant Operator attribute to pre mapping operator.
6. Drag two dummy tables and connect source to target. (ex : drag t1 (table) tab two times and connect.
7. Validate and deploy the mapping.
8. grant necessary grant command to rep_owner user to rep_user user.
(Note : target truncateFirst = "FALSE" by default truncate the table. So you have to give grant privileges
To rep_user , select ,insert, delete privileges.
9. Execute the mapping , and check EMP table. (Note : before loading EMP table delete all records ).

Loading XML file into DB Table

Hi

Loading XML files into an 8.0.6 database...

Hi,
I've got an Oracle 8.0.6 instance (Sun E250 Solaris 5.7) with multiple import data feeds. I am currently using SQL*Loader to load this data which are flat text delimited files. My data feeds will soon be supplying XML files instead of these flat files which is great, unfortunately, I will not be able to upgrade in 8.1.7 in time so that I can use the XML parser.
Is there anyway I can use SQL*Loader or some other tool to load XML files into my 8.0.6 database? If there is a way, could someone please send the information I would need to help perform this task?
Thanks for all your help...

Check out the Oracle XDB Developer's Guide, Chapter 3. There is an example of using BFileName function to load the xml files from a directory object created using create or replace directory. It works really well.

Best method to load XML data into Oracle

Hi,
I have to load XML data into Oracle tables. I tried using different options and have run into a dead end in each of those. I do not have knowledge of java and hence have restricted myself to PL/SQL solutions. I tried the following options.
1. Using DBMS_XMLSave package : Expects the ROWSET and ROW tags. Connot change format of the incoming XML file (Gives error oracle.xml.sql.OracleXMLSQLException: Start of root element expected).
2. Using the XMLPARSER and XMLDOM PL/SQL APIs : Works fine for small files. Run into memory problems for large files (Gives error java.lang.OutOfMemoryError). Have tried increasing the JAVA_POOL_SIZE but does not work. I am not sure whether I am changing the correct parameter.
I have read that the SAX API does not hog memory resources since it does not build the entire DOM tree structure. But the problem is that it does not have a PL/SQL implementation.
Can anyone PLEASE guide me in the right direction, as to the best way to achieve this through PL/SQL ??? I have not designed the tables so am flexible on using purely relational or object-relational design. Although would prefer to keep a purely relational design. (Had tried used object-relational for 1. and purely relational for 2. above)
The XML files are in the following format, (EXAMINEEs with single DEMOGRAPHIC and multiple TESTs)
<?xml version="1.0"?>
<Root_Element>
<Examinee>
<MACode>A</MACode>
<TestingJID>TN</TestingJID>

Thanks for the help.

Please refer to the XSU(XML SQL Utility) or TransX Utility(for Multi-language Document) if you want to load data in XML format into database.
Both of them require special XML formats, please first refer to the following docs:
http://otn.oracle.com/docs/tech/xml/xdk_java/doc_library/Production9i/doc/java/xsu/xsu_userguide.html
http://otn.oracle.com/docs/tech/xml/xdk_java/doc_library/Production9i/doc/java/transx/readme.html
You can use XSLT to transform your document to the required format.
If you document is large, you can use SAX method to insert data into database. But you need to write the code.
The following sample may be useful:

Option to load XML data into BI 70

Hi All,
I have read some postings on forums and also have read the "HOW TO load XML data in BW" guide. I am confused when I read the SAP online help documentation for loading XML data .
Question : Out of the 3 options listed below which option is best suited for loading XML data into BW . XML file is going to be provided by 3rd party company ?
Thanks and appreciate any input .
Smith .
Here is what I found for BI 70 EHP1 help :
http://help.sap.com/saphelp_nw04s/helpdata/en/b2/e50138fede083de10000009b38f8cf/frameset.htm
Data is generally transferred into SAP BW by means of a data request, which is sent from SAP BW to the source system (pull from the scheduler). You can also send the data to SAP BW from outside the system. This is a data push into SAP BW.
A data push is possible for various scenarios:
●     Transferring Data Using the SOAP Service SAP Web AS
●     Transferring Data Using Web Services
●     Transferring Data Using SAP XI
In all three scenarios, data transfer takes place using transfer mechanisms that are sufficient for Simple Object Access Protocol (SOAP); the data transfer is also XML-based.
The SOAP-based transfer of data is only possible for flat structures. You cannot transfer hierarchy data.

Hi,
I feel you can go with 2nd option. But still wait for some more inputs from Experts........

Suman

Loading XML file into non-XML table(s)

HI Gentlemen,
I successfully registered my schema and generated an xml-based table and a TYPE. However, I do not have the table that would correspond to this TYPE. How do I get to it? How can I use FTP or HTTP protocol to load actual data from the corresponding .xml file into this table?
Thanks in advance, kind regards from
Miklos HERBOLY

You need to include the XML schema location information in the XML documents to point to the registered XML schema.
For example,
If you register an XML schema to XML DB with "http://www.example.com/po.xsd"
In the XML document, the xml schema location can be:
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.example.com/po.xsd http://www.example.com/po.xsd">
For more information, you can check the example in the following page:

This all works just fine, however, it's not quite what I need. For starters, the multiple tag data is concatenated and when I try to specifically query it out using a where clause I get ORA 22950. So, not sure how to deal with that.
Is it possible to use sqlldr to get the 200MB XML file loaded into a table like that above?
Now, given multiple "feature" and "category" data per "MainName", I need to use the SQL to dump the XML data into a set of tables built to model the structure of the XML...
roughly..
Main_Table (
ID1 Varchar2(10)
ID2 varchar2(10)
ID3 varchar2(10)
desc varchar2(100)
Features_Table (
ID1 varchar2(10)
feature varchar2(100)
Category_Table (
ID1 varchar2(10)
name varchar2(100)
attribute varchar2(100)
What are the groups recommendations here? Should I continue down this route or is there a better way?

When I suggested the option to parse the XML in PL/SQL I was referring to pulling the data into PL/SQL and then performing all parsing activity against the PL/SQL copy and you don't need to make SQL calls.
Here is a quick sample for parsing out all the Category/name elements from the XML once it is loaded into PL/SQL
DECLARE
l_index     PLS_INTEGER;
l_category XMLTYPE;
l_db_row    XMLTYPE := XMLTYPE('<?xml version="1.0" encoding="UTF-8"?>
<MainTitle Version="1.0" Date="2009-01-11">
   <MainName>
      <ID1>A</ID1>
      <ID2>ABC</ID2>
      <ID3>ABC123</ID3>
      <Desc>Some text</Desc>
      <feature>f1</feature>
      <feature>f2</feature>
      <Category>
         <name>n1</name>
         <attribute>more stuff</attribute>
      </Category>
      <Category>
         <name>n2</name>
         <attribute>even more stuff</attribute>
      </Category>
      <Category>
         <name>n3</name>
         <attribute>different stuff</attribute>
      </Category>
      <Category>
         <name>n4</name>
         <attribute>More of the same</attribute>
         <attribute>But different still</attribute>
               <attribute>Even more different junk</attribute>
          </Category>
     </MainName>
</MainTitle>');
BEGIN
   l_index := 1;
   WHILE l_db_row.Existsnode('/MainTitle/MainName/Category[' ||
                             To_Char(l_index) || ']') > 0
   LOOP
      l_category := l_db_row.Extract('/MainTitle/MainName/Category[' ||
                                       To_Char(l_index) || ']');
      dbms_output.put_line(l_category.extract('Category/name/text()').getStringVal());
      l_index := l_index + 1;
   END LOOP;
END;You could repeat the WHILE loop to parse out the attribute column as well since it repeats. This is what Dave's post was showing and what I was referring to.
Hint: If you are trying to use .extract to go after an optional node, you need to verify the node exists via existsNode first. If you don't you can get an "ORA-30625: method dispatch on NULL SELF argument is disallowed" error when trying to extract a non-existent node.

Loading XML Document into Structured Storage

HI Everybody,
I am confronted with a BUG in Oracle which is being fixed but will last a long time. I have a relatively complex Schema with manifold includes, imports and inheritances which I can register successfully. The object-relational table is also generated. But loading the instance document with INSERT INTO... fails due to severe internal error. I have not yet tried SQL*Loader, however.
Please, does anyone know a safe alternative method to parse and load? Structured storage is mandatory because I need to retrieve individual elements and attributes. Instance documents are big, ca. 20 MB.
Thanks, regards
Miklos HERBOLY

HI,
Oracle version is 11.1.0.7.0.
Metalink found three bugs related to the error ORA-00600: Interner Fehlercode, Argumente: [qmxConvUnkType], [], [], [], [],
The bugs are:
BUG 8644684 ORA-600 [QMXCONVUNKTYPE] DURING INSERT INTO SCHEMA-BASED TABLE
BUG 8671408 INSERT OF XML DOC INTO AN XML SCHEMA STORED AS BINARY XML FAILS WITH ORA-30937
BUG 8683472 SCHEMA EXECUTABLE RETURNS INCORRECT ERRORS DURING VALIDATION AGAINST XML SCHEMA
Well, I have to look round in XML DB Forum yet.

Loading XML File into Oracle 10G XE

I am trying to load an XML file into 10G XE from the Utilities interface, I have created a Table to load into but when I try to load I get the following cryptic error "XML Load Error". There is no other information, can someone give me some insight where to start to resolve this problem?

The error messages when importing fails provided by APEX 2.1 are not very useful as they do not provide any clue...
If possible, you can try to load XML file with SQL*Loader - probably you will get then more useful error messages.

How to load XML files into ORACLE8i database?

SAP data is being extracted into XML format (via IDOC) files which are being transferred to an ORACLE8i box. There will be a large amount of data transferred on a daily basis which will include updates and inserts. From all the information that I have read on this subject there are 2 options available :
1. XML-SQL Utility - which converts XML into INSERT, UPDATE or DELETE SQL. There does not appear to be that much functionality available by this method for decodes, transformations on the input data.
2. SQL*Loader - There was a statement in 1 piece of documentation stating that SQL*Loader could be used for loading XML format data files. I cannot however find any further information on how this is achieved or how it works.
If anyone has any experience in loading XML format data files using either of the above methods (preferably SQL*Loader as it has more functionality) then could you please provide me with examples or guidance on this matter? Any help would be greatly appreciated as I am not familiar with XML format data files. I am from an Oracle 7.3 background but do not have much experience with Oracle 8 onwards.

We are loading XML into our database using CLOB datatypes. We don't use the XSU for inserts as it is too slow. We parse the incoming XML document into a PL/SQL record type and then build a generic insert. This might not work well if you have many tags to parse into columns. We also store the entire XML CLOB into a column without parsing the individual tags into separate columns. We then use Intermedia Text for fast, index-based searching within the XML column.
Check out The Oracle XML Portal website for code examples on how to do this:

Load XML content into HTML enabled TextField

I'm trying to figure out how to use html such as <br />
loaded from an XML element into a TextField.. if I use something
like
<desc>my description<br />line 2</desc> I
get 3 nodes instead of one when loading the XML file. If I use
something like <desc>my description<br />line
2</desc> then I get <br /> in the actual text.
Can anyone clue me in as to how to store HTML in an XML
element so I can load the content into a Dynamic TextField with
HTML enabled?
Thanks much!

use the latter in your xml and use the htmlText property of
your html-enabled textfield to display your text.

Loading XML Data into Relational Table

Hello,
I receive an XML file generated from another tool (on Windows), I am trying to create a Linux shell script that will gather the needed XML file from my Linux database server, then have Oracle use this file to load the XML data into a relational table. This activity & data will be needed on an ongoing basis.
I have tried this two ways. First, I loaded the XML document into the database and tried to extract the data directly from the document, but that is not working. Now I want to try to read the data directly from the file on the server via select, however I am not getting any data returned. In the Select statement below, I am simply trying to query the data to see what is returned for my testing.
Create Table ci_results_table (transactionID Varchar2(100), //transactionID should be PrimaryKey but was getting NULL value errors during insert test, so removed PK
message Varchar2(200),
ci Varchar2(50),
processeddate xmltype,
status Varchar2(50),
sourcefile VarChar2(100));
select x.*
from XMLTable(
     'TSPLoadResults/Results'
     PASSING xmltype(bfilename('CMDB_DEVADHOCRESULTS_DIR','LoadResults-HP_146.results.xml'), nls_charset_id('AL32UTF8'))
     COLUMNS
       transactionID Varchar2(100) PATH 'TransactionID',
       Result XMLType PATH 'Result',
       Message Varchar2(200) PATH 'Message',
       PrimaryKey Varchar2(50) PATH 'PrimaryKey',
       ProcessedDate date PATH 'ProcessedDate',
       Status Varchar2(50) PATH 'Status',
       SourceFile VarChar2(100) PATH 'SourceFileName'
   ) x
Eventually I will need to build on this to limit the data returned to those records where SourceFileName is like 'HPDS%' and insert what is returned in to the ci_results_table. Attached is a sample Results XML file I am trying to load, It is named "ResultsTransformedtoUnix" because I used dos2Unix to convert it to Unix which may be right or wrong. (The output file I send out has to be transformed to DOS format before the other application can read it). Original file (before Unix conversion) named in script is also attached.
Please help. Thank you!

Hi,
I see some wrong things in your query.
1) The obvious one, explaining why you're not getting any data : there's a typo in the XQuery expression, it's "Result" not "Results"
2) ProcessedDate cannot be extracted as a date (at least not directly) since it actually represents a timestamp, use TIMESTAMP WITH TIME ZONE datatype and cast back to DATE in the SELECT clause
3) transactionID is an attribute, it must be accessed with '@' (or 'attribute::' axis)
4) If the file encoding is truly ISO-8859-1 as the prolog suggests, then do not use AL32UTF8 but the corresponding charset name : WE8ISO8859P1
Here's the working query :
select x.transactionID
     , x.Message
     , x.Primarykey
     , cast(x.ProcessedDate as date) ProcessDate
     , x.Status
     , x.SourceFile
from XMLTable(
       '/TSPLoadResults/Result'
       PASSING xmltype(bfilename('XML_DIR','LoadResults-HP_146.results.xml'), nls_charset_id('WE8ISO8859P1'))
       COLUMNS
         transactionID Varchar2(100)            PATH '@transactionID',
         Message       Varchar2(200)            PATH 'Message',
         PrimaryKey    Varchar2(50)             PATH 'PrimaryKey',
         ProcessedDate timestamp with time zone PATH 'ProcessedDate',
         Status        Varchar2(50)             PATH 'Status',
         SourceFile    VarChar2(100)            PATH 'SourceFileName'
     ) x
Using this query directly over the file will only perform decently (for large files) on 11.2.0.4 and onwards.
On prior versions, first load the file in a (temporary) XMLType column with Binary XML storage and SELECT from there.
because I used dos2Unix to convert it to Unix which may be right or wrong.
This conversion shouldn't be necessary.
