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.

Xml sql utility limitation

Hi, Oracle:
Are there upper limit with regard to OracleXMLSave.insertXML(),
such as upper limit for field size, upper limit for file size,
uppper limit for number of columns you can have, upper limit for
number of rows(records) you could have?
Prompt response will be greatly appreciated!
Thanks,
Tony

First, let me thank you for the reply.
Here is the situation: I want to insert a xml file about 3 MB
into an Oracle 8.0.5 table, in the table, I have a field called
resume which is of type LONG. I am using OracleXMLSave.insertXML
to do the insertion and oci8 jdbc connection. Here the error

If I have a smaller size file, such as 1MB, it works. What could
be wrong? Oracle JDBC driver? the implementation of
OracleXMLSave.insertXML?
Here is the source code of my java program:

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

Help Needed -- Oracle XML/SQL utility and PL/SQL parser

<?xml version="1.0" standalone="no"?>
<abc>
<def>
<ghi>test</ghi>
</def>
<jkl>
<mno>testing</mno>
</jkl>
</abc>
We can store the <def> tag in one table say def and <jkl> tag in another table say jkl.
Is there a way to combine def and jkl and insert in one table so that there in one row with two columns test and testing??

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).
Thx

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");

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

XML SQL Utility - settagcase - all tags are upper or lower

I am using the XML SQL Utility (XSU) for PL/SQL to generate a xml document from some tables and objects. Is it possible to have the xml elements start and end tags appear in the case of the objects I have defined (i.e. CamelCase)? I can either have them appear as all upper or all lower case. However the oracle documentation has a SETTAGCASE function with an option for "as are". Is this supposed to allow for the case to follow how i have defined the fields in the object? If not is there a way?
For example here is an object
create or replace TYPE     CREDIT_APPLICANTTYPE AS OBJECT
First VARCHAR2(15 BYTE),
Last VARCHAR2(35 BYTE),
Middle VARCHAR2(1 BYTE),
Suffix VARCHAR2(3 BYTE)
);Settagcase 0 option doesn't seem to do anything different than the upper_case option when i generate the xml
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_xmlque.htm#i1033636
set serveroutput on
declare
queryCtx dbms_xmlquery.ctxType;
charstring VARCHAR2(255);
outxml CLOB;
begin
    queryCtx := dbms_xmlquery.newContext('select CREDIT_APPLICANTTYPE(''Joe'',''Smith'',''A'',''Jr.'') as AppName from dual');
    dbms_xmlquery.settagcase(queryCtx, 0);
    outxml := dbms_xmlquery.getXml(queryCtx);
    dbms_xmlquery.closeContext(queryCtx);
    charstring := dbms_lob.substr(outxml, 255, 1);
    dbms_output.put_line(charString);
end;Output is in uppercase but i would like camel case:
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1">
<APPNAME>
<FIRST>Joe</FIRST>
<LAST>Smith</LAST>
<MIDDLE>A</MIDDLE>
<SUFFIX>Jr.</SUFFIX>
</APPNAME>
</ROW>
</ROWSET>

Actually I figured out the issue. Oracle automatically outputs the column alias as upper case unless you put it in quotes. I defined my object like this and it works with settagcase 0
create or replace TYPE CREDIT_APPLICANTTYPE AS OBJECT
"First" VARCHAR2(15 BYTE),
"Last" VARCHAR2(35 BYTE),
"Middle" VARCHAR2(1 BYTE),
"Suffix" VARCHAR2(3 BYTE)
);

XML SQL Utility (XSU) in BPEL process

Is it possible to use XML SQL Utility (XSU) in BPEL process? I would like to generate XML from a query.

I'm using Oracle 8.1.6.1.0 (but instead of classes12.zip I'm attempting to use ojdbc14.jar)

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.
Michael

XML SQL utility

Hi,
When I try to execute this query using XML SQL utility
I am getting the following error. I had declared 'XMLGEN &
GETXML' as CLOB and tried but got the same error. Advice me. I
am struggling to find the solution using XSQL Servlet..but
couldn't get..I spend one week on that..no results...this is the
second trial. Is there any online help or service to do that.
xmlString := xmlgen.getXML('select * from scott.emp');
ERROR at line 9:
ORA-06550: line 9, column 16:
PLS-00201: identifier 'XMLGEN.GETXML' must be declared
ORA-06550: line 9, column 3:
PL/SQL: Statement ignored
I have Oracle XML parser for Java 2, and XML SQL utility and
oracle 8i database....
This is the query.........(Your example)
declare
xmlString CLOB;

position integer := 1;
charString varchar2(4000);
i binary_integer := 0;

loop
dbms_lob.read(xmlString,amount,position,charString);
dbms_output.put_line(charString);
position := position + amount;
end loop;
exception
when no_data_found then
dbms_lob.close(xmlString);
dbms_lob.freetemporary(xmlString);
end;

Have you loaded the xmlgenpkg.sql in the schema in which you
are trying to execute your PL/SQL block?

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?

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

XML SQL Utility:Why it doesn't work?

I am trying to use the XML SQL Utility
by modifying the given example samp1.java

Is there any thing wrong? Thanks.
(The classpath setting is ok, I think)

// print out the result

Firstly I think it is because the XML SQL Utility does not work with JDBC-ODBC driver.
So I try it again with Oracle driver.
But it still doesn't work? Why?

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.
Regards,
Manoj

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+
