XML and Database

Hi,
I have a XML file with Emp data on it. I have to load(data) into database(ver8.1.6).
How can i do this ? Does any one have script ?
Thanks in advance.

Do you want to load the XML document in its entirity? Or do you want to parse the data out and insert it in a table.

Mapping XML and Database

Hi,
I have a design problem in my application. It goes on like this:
For every XML Request-Response query, I have a Session Bean which accesses database tables. I have to refer to 4-5 tables to fulfil each request. All the tables follow the parent-child relationship(onto 4-5 levels, depending upon the number of queries) which means for one row in parent table there are multiple rows in child tables and so on.
Now, in my XML response, I need to follow the same schema in form of tags. For example:
<table1Info>
<data1>1212</data1>
<table2Info> (tags could be multiple)
<data2>1212</data2>
<table3Info> (tags could be multiple)
<data3>1212</data3>
<table4Info> (tags could be multiple)
<data4>1212</data3>
</table4Info>
</table3Info>
</table2Info>
</table1Info>
So far, so good! I can happily select data from multiple tables and generate the XML response by serially concatenating the response string. My problem is that I want to write a single query to fetch all the data instead of fetching data corresponding the parent tag and then making another query to fetch data from child table(which corresponds to child tag).
If i do a join of all tables in a single query, I need to do a lot of checking in java code inside the loop and figure out when a parent data has changed and the upcoming values correspond to next parent data(and thereby close all the child tags and open the next parent tag). It can sometimes become quite messy and cumbersome. Is there a cleaner way of doing it? Any ideas wud be welcome...Please let me know if i need to elaborate more ..
Thanks,
Prashant

What is wrong with issuing the query each time for the child? Performance? It more accurately models what you are trying to do than the approach you mention.

XML and database of documents

Please help to a newcomer to XML:
I intend to create XML based database of documents and present
it on Web.
Documents are of fixed structure however few elements will be up
to ;K of size. They will be static.
Total size of a document is less then 4K, expect some 10,000+
entries ?
Need to
- Search in DB by keywords and also support free search in
documents. Once found and selected,full document is displayed.
- Create discussion topic with threads, where contributions may
have pointers to selected elements of these documents and these
links are higlighted.
Please advise how to work on it and also how to handle inserts
into DB.
- Should one store the whole documents including element tags as
CLOB ?
Data will be prepared from scratch so my though is to
prepare some templates to be used by a XML editor to prepare
XML files. Create DTD (or use an existing one) and use parser
(which one is suitable?) to validate correctness.
Q1: Some elements ttheoreticallyv ask for being handled as
attributes. There are, however some 50+ possible values and I
donFt think a DTD should be prepared to handle this by itself!
Is this appropirate ?
Q2: How to insert data ? Are there tools available or should
one process data using Java or PL/SQL and then insert into
appropriate tables?
Q3: Use interMedia to search DB, then XSQL to retrieve relevant
data and present via XSL ?
Thanks !

Hi,
Thank you for your answer,
Actually this is the way I'm doing the merge process today: using Java code with DOM to merge all documents to one XML document.
I'm looking for ways to not using the DOM parsing becasue it is very expensive in CPU and memory (DOM is the worst XML parser in a performance point of view).
SAX parsing is also not appropriate because the merge process that I need to do is vey complicated.
This is the reason why I thought of using XSLT.
My question is if XSLT can do the work or is it way off?
Thanks,

Reading and Writing from XML into database

Dear all,
We have a requirement where we have to upload data to FTP location in XML files, and then read from this into our database daily 2-3 times a day.
We have oracle 11g database, can someone kindly guide me how we can acheive this.
Also is there any tool for this? my management is thinking of purchasing one if it exists.
thank you

Here's a sample (a couple of years old now) from his blog of mixing XML and SQL: http://www.liberidu.com/blog/2010/07/29/external-views-xml-based/
It's the first one I happened to get to when I did a search on his blog for: external table.
Some time back he sent me an example of running an SQL statement from the database which accessed the internet and pulled back the content of one of my blog pages in a form that would allow me to do: "insert into table select from {XML call}"
Unfortunately I can't find the code right now - I know I stored it somewhere to make sure I didn't lose it but ...

Database updation using XML and stored Procedure?

Hello,
I want to perform updation in multiple tables using XML files.Please suggest can I do updation using xml and stored procedure.
If yes then which is more efficient and takes less time.
1.Updation using xml files only
2.Updation using xml files with stored procedure.
3.Stored procedure alone.
If direct xml and stored procedure communication is possible.then please write how.
Thanks in advance for any help.

Here's a sample. The next code drop of the XSQL Servlet will make the easy-to-do from within XSQL Pages:
package package1;
import org.w3c.dom.*;
import java.sql.*;
import oracle.jdbc.driver.*;
import oracle.xml.sql.query.OracleXMLQuery;

XML and Oracle 8i Lite

Hi Wizards
I'm in an endeavour to do the following things -
1.Generate XML output from Oracle 8i Lite database
2.Modify the XML and update the database taking the modified XML.
My java platform is JDK 1.2. I've used the XML SQL Utility for Java, and in doing so i've been successful with the 1st step. I've used the Oracle 8.1.6SDK JDBC Driver which is compatible with JDK 2.The code fragment is like the following -
import java.io.*;
import java.sql.*;
import java.math.*;
import oracle.xml.sql.query.*;
import oracle.jdbc.*;
import oracle.jdbc.driver.*;
public class orasql1
public static void main(String args[]) throws SQLException
Connection conn = null;
String tabName = "emp";
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:POlite", "SYSTEM", "manager");
catch (Exception e) {
System.out.println("Oracle Connection error\t:");
System.out.println(e);
System.exit(0);
OracleXMLQuery qry = new OracleXMLQuery(conn, "select * from " + tabName);
qry.setRowsetTag("SCHEMADOC_1");
qry.setRowTag("EMPLOYEE");
qry.setStyleSheet("emp.xsl");
String xmlString = qry.getXMLString(true);
conn.close();
try {
File output = new File("emp.xml");
FileWriter xmlFile = new FileWriter(output);
xmlFile.write(xmlString,0,xmlString.length());
xmlFile.close();
catch (Exception e) {
System.out.println("Output file error\t:");
System.out.println(e);
System.exit(0);
I am putting some sample code for step 2 in the following section -
import oracle.xml.sql.dml.*;
import java.sql.*;
import oracle.jdbc.driver.*;
import oracle.jdbc.*;
import java.net.*;
public class orasql2
public static void main(String args[]) throws SQLException
Connection conn = null;
String tabName = "emp";
String fileName = "emp.xml";
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:POlite", "SYSTEM", "manager");
catch (Exception e) {
System.out.println("An error has occurred.");
System.out.println("Please check your CLASSPATH variable..");
System.out.println(e);
System.exit(0);
OracleXMLSave save = new OracleXMLSave(conn, tabName);
URL url = save.createURL(fileName);
save.setRowTag("SCHEMADOC_1");
int rowCount = save.insertXML(url);
System.out.println("Successfully inserted "+rowCount+" rows into "+tabName);
conn.close();
Compiling the above code is fine, no errors! But while running the application I get the error -
Exception in thread "main" oracle.xml.sql.OracleXMLSQLException: java.lang.Class
CastException: oracle.lite.poljdbc.OracleStatement
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:345)
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:248)
at orasql2.main(orasql2.java:27)
My question is whether this thing can be done at all using Oracle 8i Lite? If so then how?
Waiting for ur advices.

It looks like be a classpath issue. Would you check with the class name.

XML and Web Service Data Source Missing in Crystal Reports for VS

I would like to use a Web Service as the data source for a Crystal Report that will be running outside of my Visual Studio application. So setting the data source to the web service in code is not possible. My understanding is Crystal Reports has a connection (in the Database Expert under New Connection) named XML and Web Service. Here you can select web service and enter the WSDL URL for the web service. However it does not appear in the list for Crystal Reports for Visual Studio. Does this connection type come with the Visual Studio version of Crystal Reports and if not is their a way to obtain it?
Thank you for your assistance.

None of the bundled versions of CR have the driver. Reason is that the driver responsible for these connections requires the Java framework and I suspect MS would not be too pleased if we installed the Java framework. The stand alone versions, since they are not part of any bundle can and do install the Java framework and the driver. Note that even the latest release of CR - CRVS2010 does not have the driver as it essentially becomes a bundle or a VS2010 plug-in.
So, the short of it is; you have to obtain a stand-alone version of CR. I'd recommend CR 2008 (12.x) as CRXI R2 will run out of support in June of this year.

Business Components and Database Views - Trouble Creating

I am trying to create a business component that contains a View that I created in my database. When I get to the fnnal step of creating the business component and it begins to generate the XML and Java code, it bombs out and says that the view object does not support ROWID. I just need to select only GridControl of this view.
Any suggestions/help would be appreciated. I could not find any info in the JDeveloper help.
null

Some options:
[list]
[*]Create the entity using the Entity Wizard instead of reverse engineering it from a table. In the entity wizard you can specify the table/view name, then indicate which attribute should function as the primary key.
[*]Don't bother creating an entity object for this view. You can just create a view object with an "expert mode" query that selects against your database view. It does not need an entity object. Note, however, that without an associated entity you won't get "uniquing" of entity level values, so if another view object being used by the same use changes the data that this grid is showing, the updates won't be automatically synchronized if you go this route.

How .xml and ~/Music/iTunes/iTunes Music work

Have posted this before, just reposting in hopes of getting an answer...
In 2.5 years we've had 3 hard drives, 2 logic boards, a power supply, multiple crashes, etc. During all this time of data recovery and frantic backing up, I managed to duplicate all but the most recently added songs in my iTunes folder. In the past I had deleted these duplicates from the Music library. So, I don't think I had these duplicates before re-importing or adding my songs to the iTunes program after an erase and install two days ago. The erase and install did not get rid of our erratic computer problem(s), and Apple is graciously sending us a new iMac.
I'd like to clear up this duplicate issue before importing my library to iTunes on the new computer. As far as I can tell, I'll have to delete each duplicate by hand. My question relates to how the iTunes Music folder, the iTunes Music Library.xml doc, and the actual iTunes program work together.
(1) Should I go into ~/Music/iTunes/iTunes Music/album folders and delete each song by hand from there? Or should I import all the duplicates in these folders and delete them from within iTunes? In the end, I want no duplicates in the iTunes program and no duplicates in my iTunes Music/album folders.
(2) Could the .xml file be saving data that would cause these duplicates to be recreated? Should I resave it after deleting duplicates? Does the .xml file affect the Music library at all?
(3) This last time, I don't know if I officially "imported" or "added" music or what. iTunes had been reinstalled, was empty. First, I put iTunes Music Library.xml on my desktop, and then went to File>Import (like on http://docs.info.apple.com/article.html?artnum=93313). But, absolutely no music showed up in the music library. All my playlists showed up, and they had no music. Only radio stations we had put in playlists showed up. In the referenced article, it says NOT to add music when you are doing this, so I didn't. THEN, I dragged ~/Music/iTunes/iTunes Music and dropped it into iTunes. All the duplicates were created then, I believe.
Did I "import" or "add", or what? Did I cause duplicates to be created? Should I drag-and-drop ~/Music/iTunes/iTunes Music or import it BEFORE I do the .xml thing? I believe next time I'll take advantage of the File>Back Up To Disc function, and I'm assuming this won't happen.
Thank you for your help!
Deanna
P.S. After my initial post, somebody suggested the article at
http://docs.info.apple.com/article.html?artnum=93732
However, this article deals with .xml and iTunes Music Library, which is a database file. I need info on .xml and iTunes Music Folder, the folder that physically holds all my iTunes.

Generating XML from database

I'm a total newbie in XML DB and need advice on generating XML from database.
The situation is the following: there is a legacy web application which uses an XML document as a configuration file. This document conforms to some well-defined schema. For instance:
<config>
     <title value="TITLE" />
     <subtitle value="SUBTITLE" />
     <style url="default.css" />
     <widgets>
          <widget id="1" opened="true" />
          <widget id="2" opened="false" />
     </widgets>
</config>
It contains portions of static data which are common for all users as well as dynamic personal data.
Dynamic data comes from two sources:
1) security considerations (for instance, not all widgets are available for some users) - thus the "master" configuration content must be filtered, but not otherwise modified;
2) user preferences (for instance, user can set widget2 to be opened by default) - thus values of some attributes must be different for each user. When the user saves her preferences, the entire document with new values is posted back to server.
We want to try to store user preferences, apply security and generate personalized configuration documents using XML DB.
So we need advice on storage models and generation procedures - which should be more efficient and easy to support or extend.
Please note, that there is no requirement to actually store data as XML.
Thanks in advance!
P.S.: Sorry for the incomplete initial post.

XML and its influence over program design (2 issues)

I have 2 open questions about XML and Java. I apologise if they are not clear-cut or specific enough, but really I am fishing for sound advice.
I am trying to develop a J2EE application but find myself stuttering at an early stage because I cannot decide on the best design for my application. Part of my problem is a lack of experience with the different J2EE technologies/API (especially XML APIs), and the realisation that there is 101 ways to do what I want to do.
A major issue is this: my application basically is concerned with representing conversations between the server and a user, e.g. a simple sequence of yes/no questions asked by the server to the user, which the user replies to in turn. I believe that the XML format would be a very suitable way to represent these conversations. My first question is:
* Should the decision to use XML as a storage format influence the design of the rest of the program? I feel that in choosing XML to represent the conversation data, I am stuck thinking about the rest of my program in a XML way (i.e. doing everything using a DOM etc.). Am I right in thinking that my program should be designed in such a way that an XML-based storage system could be easily interchanged with, say, a relational flat-tabled database?
My second question is:
* Imagine that each conversation contains one or more questions, and there are, say, 4 different types of question (e.g. yes/no, multiple choice, etc.). Each of these needs to be handled in a different way. Is there a good pattern or recommended way of handling this sort of situation in code, ideally avoiding a big 'if' or switch statement (e.g. if the node is of "ABC" type do this, else if it is "yes/no"...). It would be great if one could easily add new types of question to the XML and then similarly one can make easy additions to the code to cope with these new cases.
Thank you very much indeed for any advice.

I am trying to develop a J2EE application but find
myself stuttering at an early stage because I cannot
decide on the best design for my application. Part of
my problem is a lack of experience with the different

questions asked by the server to the user, which the
user replies to in turn. I believe that the XML
format would be a very suitable way to represent
these conversations. My first question is:
XML might be overkill if it's just a question followed by an answer and neither contains complex hierarchical data structures.
* Should the decision to use XML as a storage format
influence the design of the rest of the program? ICertainly not.
XML should represent data structures that are natural to your program, thus becoming a tool rather than forcing its structure upon you.
feel that in choosing XML to represent the
conversation data, I am stuck thinking about the rest
of my program in a XML way (i.e. doing everything
using a DOM etc.). Am I right in thinking that my
program should be designed in such a way that an
XML-based storage system could be easily interchanged
with, say, a relational flat-tabled database?
Flexibility is good to keep in mind, but at the moment I'd worry about just getting something to work.
* Imagine that each conversation contains one or more
questions, and there are, say, 4 different types of
question (e.g. yes/no, multiple choice, etc.). Each
of these needs to be handled in a different way. Is
there a good pattern or recommended way of handling
this sort of situation in code, ideally avoiding a

"ABC" type do this, else if it is "yes/no"...). It
would be great if one could easily add new types of
question to the XML and then similarly one can make
easy additions to the code to cope with these new
cases.
Think of a factory that creates the handlers on the fly based on the actual message received.
If the factory makes use of some mapping construct to do so there's no need for any conditionals at all in your decision tree.
I've myself used XML structures successfully to define such mappings (and so have others) on disc, but simple ones can be easily represented using just a properties file.

UTF-8, Unicode, XML and windows problems

Hi there,
I'm developing an application which uses a lot of russian text.
This russian text is stored in XML and can be sent to a server remotly
I use the standard javax.xml libaries to parse the xml files and DBunits XMLWriter to write generate XML strings.
The XML returned by the DBunit stuff is UTF-8, but its inside a UTF-16 string.
So when I generate xml and print it out I get something that looks like the following:
�� ?��Thats ok, beacause I can stick that streight into a file when writing files and it works.
But the problem comes when sending the XML over the server.
The sending implentation I use must be able to send java generated utf-16 and xml read utf-8.
So I convert the XML from utf-8 to utf-16, using the following:
byte[] stringBytesISO = isoString.getBytes("ISO-8859-1");
utf8String = new String(stringBytesISO, "UTF-8");And that works perfectly on my linux system.
However when I run it on windows, it only seems to convert some of the characters

Ideally, you should use the same library to write the XML as you do to read it, but you definitely shouldn't be using DbUnit in this context.
The XML returned by the DBunit stuff is UTF-8, but its inside a UTF-16 string. That should never happen. XML is just text, and text can either be in the form of a Java string, or it can be stored externally using a text encoding like UTF-8. Never mind that Java strings use the UTF-16 encoding; you don't need to know or mention that. Encodings only come into play when you're communicating with something outside your program, like a file system or a database.
When you generate the XML, you specify that the encoding is UTF-8. When you read the XML, you specify that the encoding is UTF-8. That's all.

Search for a tag in xml and modify the content

Hi,
I am quite new to using xml db and i want to know how to search a xml, modify a tag value inside xml and replace the content in xml.
Please help me to find a solution for this.
Regards,
Sprightee

Hi,
First important thing : give your database version (SELECT * FROM v$version).
Please also provide some sample data :
- a typical XML document you're working with (or abridged version)
- explain what change(s) you want to do, or give expected output
- if you're using a table to store the XML (which is preferred), give the DDL

Porting data from Oracle8i to XML and from XML to Oracle 10g

Hai
I have a client database (using oracle 8i) and a server database (oracle 10g).
Due to lack of leased line connectivity i want to port these offline data from 8i to 10g
using a modem(dial up connection).Is there is any way to port data from 8i to XML
and from XML to 10g.
thanks in advance
dejies

Thanks Nicolas,
As per documentation, it seems to be difficult for export/import from Oracle8i to 10g. Is that any way to achieve this? I have to append the newly imported data with old or exisiting data into Oracle10g.
