Updating a database using XML SQL Utility

Hi all,
It seems that the Oracle XML SQL Utility provides only to insert rows into a table/view. However, if one wants to update a table from an XML no support is available.
How does one proceed if this is to be achieved?
Thanks in advance.

While inserting i get a
oracle.xml.sql.OracleXMLSQLException and further a
NumberFormatException. Which parameter do I have to set to avoid
these Exceptions. I can insert the file in my local db but I get
the Exception on the server db. The value I want to insert for
expample is 30,1. Maybe the JDBC-Driver tries to convert the String ;30,1+ to an
Integer-Object. This will cause the described Exception since
the Integer-Class requires ;.+ instead of ;,+ for decimal point.
I have another problem generating an xmlfile when there
are "Umlaute" in the data. E.g. V and \. Exchanging these to Oe
and Ue than it works fine.Use ISO-8859-1 character set to work with umlauts, e.g.:
<?xml version = '1.0' encoding = 'ISO-8859-1'?>
.. but you can use the default UTF-8 encoding too, umlauts will
be replaced by equivalents as ;CŸ+

Generating multi-level XML in Oracle 8i using XML-SQL utility

Oracle 8i has a limitation when it comes to the object types. Only one-level nesting of collection is allowed. Oracle 9i apparently removes this limitation.
I am trying to generate XML for a hierarchical (conceptually) structure. To do that I am using XML-SQL utility (XSU) running agains an object view build on top of the relational data. The problem is the limit to onelevels of colelction nesting. Oracle 8i gives you a way to create a view with more levels of nesting by using references (REF). The problem is that when XSU runs agains a view with the references, it inserts the references into the XML document (instead of dereferencing them).
Is there a way to generate XML with Oracle 8i with more than two levels of collection nesting?
Thank you.

1.2 JVM crashes using XML SQL Utility 1.1.10 (NT 8.1.5)

I am trying to use the XML SQL Utility for Java (Oracle 8.1.5) to obtain a DTD or XML schema for tables in our database.
I have installed the XSU111.ZIP archive,
set the CLASSPATH and stuff, loaded the JAR
files (xmlparserv2.jar, oraclexmlsql.jar)
processed the xmlgenpkg.sql script (following the installation instructions)
When I execute the samples in Java, the JVM (JDK 1.2.2) crashes in javai.dll.
The same error occurs when I run java OracleXML getXML ....
The installation file (env.bat) lists the JDBC driver ZIP as CLASSES12.ZIP, which is of course, not available for 8.1.5, which is what the download instructions indicated is appropriate for XSU 1.1.1.
Any ideas? Do I need to upgrade to 8.1.6?
Can I patch the JDBC with classes12.ZIP.
By the way, when I execute the commands in PL/SQL using xmlgen package, everything is fine.
Regards and Much thanks

Set JDK_HOME to the directory where you install your JDK (Java Development Kit).
So instance, I've install JDK1.1.8 on my
C drive so
set JDK_HOME=c:\jdk1.1.8;c:\jdk1.1.8\bin

Have you loaded the xmlgenpkg.sql in the schema in which you

XML SQL Utility or XSQL Servlet ?

Hi,
I am trying to generate a well formed XML file by querring from oracle8i database and also include different XSL files to render different output styles.
Should I use XML SQL Utility or XSQL Servlets ??
From the documentation I see that both XML SQL utility and XSQL servlets will do the job(am I right ?). But I am sure which one I should be using.
Can any one advice me on this ?
Thanks.

Yes. You need to use the Oracle8i 8.1.6 JDBC driver with XSU, but it can connect to an 8.0.5 instance.

How to use my own DTD and table using the XML SQL utility.

Hey,
Here is my question. I have succesfully installed Oracle XML SQL utility and I had played around on that. Now I have my own DTD that too from Rosettanet(PIP). Tell me how can I use my own table, and my dtd using the existing utility. What are all the changes do I need to do. I am strugling it from past 4 days. I couldn't. Please help me!

Hi chris,
Yes, the SQL can be changed only by using Discoverer Administrator.
Open the report/workbook that is based on the custom SQL that you want to change in Discoverer Plus. Look at the Folder that is being used to select the columns of the report.
Open up the Discoverer Administrator with the id that has access to the tables referenced in the report. And the custom folder with the same name as in Disc Plus would be listed down in the Business Area (Which Business Area the custom folder belongs to can be determined with the help of disc plus).
Just open up that folder, and change the SQL in it. You can pasted your new sql in there and click on Validate SQL to validate it for errors. If no errors, then the custom folder is successfully changed.
In order to have it reflected, close your existing disc plus session and reopen it, and you can go about using the custom folder.
Hope this helps!
Thanks.

Hi,
Are u sure that it is a java enabled database? The most common
case of failure with the xmlgen package is because the loadjava
command did not succeed.
Please make sure that oraclexmlsqlload.bat file loaded all the
java procedures successfully. If not then u would have to java-
enable your database by running the initjvm script. (please see
the docs).

XML SQL Utility, Unicode

Hi,
I have some questions to the XML-SQL-Utility:
1.) Is there a bug in the oracle.xml.sql.query class:
OracleXMLQuery qry = new OracleXMLQuery(conn,"select POSITION from DATAS");
qry.setRowTag("DROW");
OracleXMLDocGenDOM gdoc = new OracleXMLDocGenDOM();
qry.getXML(gdoc);
conn.close();
Document docin = gdoc.getXMLDocumentDOM();
NodeList rows = docin.getDocumentElement().getElementsByTagName("DROW");
// The Node "DROW" wasn't found.
// It work if I do it below
NodeList rows = docin.getDocumentElement().getElementsByTagName("ROW");
// It doesn't matter what is set in the "qry1.setRowTag("DROW");"
(I use the sun parser)
2.) I have a problem by insertXML(Document);
I will insert a Document with a structure as below in my database:
<?xml version="1.0" encoding="UTF-16"?>
<ROOTDOC>
<ROW>
<DOCUMENTREF>133-12224</DOCUMENTREF>
<TEXT>hello</TEXT>
</ROW>
<ROW>
<DOCUMENTREF>133-124</DOCUMENTREF>
<TEXT>world</TEXT>
</ROW>
</ROOTDOC>
XmlDocument sdoc = new XmlDocument();
Element rootDEl = sdoc.createElement("ROOTDOC");
sdoc. appendChild(rootDEl);
Element rowEl = sdoc.createElement("ROW");
Element docREl = sdoc.createElement("DOCUMENTREF");
docREl.appendChild(sdoc.createTextNode("133-12224"));
NodeList rows = sdoc.getDocumentElement().getElementsByTagName("ROW");
int size = rows.getLength();
System.out.println("SIZE: " size "\n");
// The size is null, what's wrong ?
OracleXMLSave save = new OracleXMLSave(conn, tabName);
int rowCount = save.insertXML(sdoc);
// It didn't insert something in my table !
3.) I save Unicode UTF-16 in my database with the XML SQL Utility:
<?xml version="1.0" encoding="UTF-16"?>
<ROOTDOC>
<ROW>
<TEXT>D$55DD</TEXT>
</ROW>
<ROW>
<TEXT>tt%zu||</TEXT>
If I read it whit the oracle.xml.sql.query, it is Unicode UTF-8:
OUTPUT IS:
<?xml version="1.0"?>
<ROOTDOC>
<ROW num="1">
<TEXT>D$55--</TEXT>
</ROW>
<ROW num="2">
<TEXT>tt%zu33</TEXT>
</ROW>
I want a output as the input (Unicode UTF-16).
Can anyone please advise on the problems.
Thanks

Hi H.Ozawa,
thanks for trying but non of the solution helped me, sorry.
Question 1:
I'll try it again like this:
OracleXMLQuery qry = new OracleXMLQuery(conn,"select POSITION from DATAS");
qry.setRowTag("DROW");
Document docin = qry.getXMLDOM();
conn.close();
NodeList rows = docin.getDocumentElement().getElementsByTagName("DROW");
// The Node "DROW" wasn't found.
Question 2:
<?xml version="1.0" encoding="UTF-16"?>
<ROOTDOC>
<ROW>
<DOCUMENTREF>133-12224</DOCUMENTREF>
<TEXT>hello</TEXT>
</ROW>
<ROW>
<DOCUMENTREF>133-124</DOCUMENTREF>
<TEXT>world</TEXT>
</ROW>
</ROOTDOC>
XmlDocument sdoc = new XmlDocument();
Element rootDEl = sdoc.createElement("ROOTDOC");
sdoc. appendChild(rootDEl);
Element rowEl = sdoc.createElement("ROW");
Element docREl = sdoc.createElement("DOCUMENTREF");
docREl.appendChild(sdoc.createTextNode("133-12224"));
Element docTEl = sdoc.createElement("TEXT");
docTEl.appendChild(sdoc.createTextNode("hello"));
An error message occur:
java.lang.reflect.InvocationTargetException: java.lang.IllegalAccessError: try to access class com/sun/xml/tree/ParentNode from class project/dbase/xmlwritedb at project.dbase.xmlwritedb.main(xmlwritedb.java:33)
at java.lang.reflect.Method.invoke(Native Method)
at com.borland.jbuilder.util.BootStrap.invokeMain(Unknown Source)
at com.borland.jbuilder.util.BootStrap.main(Unknown Source)
Question 3:
I try it like below but the output is "UTF-8" encoding
OracleXMLDocGenDOM gdoc = new OracleXMLDocGenDOM();
query.getXML(gdoc);
XMLDocument docin = (XMLDocument)gdoc.getXMLDocumentDOM();
docin.setEncoding("ISO-8859-1"); //docin.setEncoding("UTF-16");
NodeList rows = docin.getDocumentElement().getElementsByTagName("ROW");
Element row = (Element)rows.item( i );
NodeList elements = row.getElementsByTagName( "DOCUMENTREF" );
So you or someone have another idea to fix this problems.
Thanks

Is XML-SQL Utility for Java run on Client Side?

A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?

So I try it again with Oracle driver.

Re: usage of XML SQL Utility

Hi there,
I have such a design issue, which I posted a few days ago and I reworded here. Hopefully, I made it clearer this time.
The working scenario, coded in Java, goes like this:
1> Given an XML string, I parse it out and get a set of values for a certain set of elements, say in one ROW.
2> I embed this set of values in the WHERE clause of a query string, do a SELECT.
3> Based on the result from the above SELECT, I do UPDATE, SELECT and INSERT to a few tables.
My question:
Could Oracle XML SQL Utility be used here? If yes, how?
From my reading so far, the Oracle XSU handles the SQL-XML and XML-SQL Mapping very well, in terms of a whole XML string. But, if at some point, I want to break the XML string and get some business logic mingled in it, say a simple calculation, how can I efficiently deal with it?
Any suggestion would be greatly appreciated. Thanks.
