How to insert XML/dtd data into oracle db
Hi,
I have posted this question on couple
sites and unfortunately I haven't received
any response. Hopefully this time,
someone can at least direct me to the
website/document/sample codes which can provide me solutions of my question.
My question is:
Given a DTD, can the XML SQL Utility generate
the database schema?
I am trying to find out how the XML data can
be loaded into the oracle database.
Thanks in advance,
Judy

A DTD does not contain enough information to do a good job at creating a database schema. It contains no datatype information, no field length information for starters, so a table created by a hypothetical DTD->to->Tables utility would be at best able to create a table with all VARCHAR2(4000) columns. Not that useful.
My book contains lots of examples of techniques for loading XML data into Oracle, include lots of sample code and a whole chapter devoted to building a flexible "XMLLoader" utility for loading XML of arbitrary size into the database.

How to insert a image file into oracle database
hi all
can anyone guide me how to insert a image file into oracle database now
i have created table using
create table imagestore(image blob);
but when inserting i totally lost don't know what to do how to write query to insert image fileHi I don't have time to explain really, I did have to do this a while ago though so I will post a code snippet. This is using the commons file upload framework.
Firstly you need a multi part form data (if you are using a web page). If you are not using a web page ignore this bit.
out.println("<form name=\"imgFrm\" method=\"post\" enctype=\"multipart/form-data\" action=\"FileUploadServlet?thisPageAction=reloaded\" onSubmit=\"return submitForm();\"><input type=\"FILE\" name=\"imgSource\" size='60' class='smalltext' onKeyPress='return stopUserInput();' onKeyUp='stopUserInput();' onKeyDown='stopUserInput();' onMouseDown='noMouseDown(event);'>");
out.println(" <input type='submit' name='submit' value='Submit' class='smalltext'>");
out.println("</form>"); Import this once you have the jar file:
import org.apache.commons.fileupload.*;Now a method I wrote to upload the file. I am not saying that this is correct, or its the best way to do this. I am just saying it works for me.
private boolean uploadFile(HttpServletRequest request, HttpSession session) throws Exception {
boolean result = true;
String fileName = null;
byte fileData[] = null;
String fileUploadError = null;
String imageType = "";
String error = "";
DiskFileUpload fb = new DiskFileUpload();
List fileItems = fb.parseRequest(request);
Iterator it = fileItems.iterator();
while(it.hasNext()){
FileItem fileItem = (FileItem)it.next();
if (!fileItem.isFormField()) {
fileName = fileItem.getName();
fileData = fileItem.get();
// Get the imageType from the filename extension
if (fileName != null) {
int dotPos = fileName.indexOf('.');
if (dotPos >= 0 && dotPos != fileName.length()-1) {
imageType = fileName.substring(dotPos+1).toLowerCase();
if (imageType.equals("jpg")) {
imageType = "jpeg";
String filePath = request.getParameter("FILE_PATH");
session.setAttribute("filePath", filePath);
session.setAttribute("fileData", fileData);
session.setAttribute("fileName", fileName);
session.setAttribute("imageType", imageType);
return result;
} And now finally the method to actually write the file to the database:
private int writeImageFile(byte[] fileData, String fileName, String imageType, String mode, Integer signatureIDIn, HttpServletRequest request) throws Exception {
//If the previous code found a file that can be uploaded then
//save it into the database via a pstmt
String sql = "";
UtilDBquery udbq = getUser(request).connectToDatabase();
Connection con = null;
int signatureID = 0;
PreparedStatement pstmt = null;
try {
udbq.setUsePreparedStatements(true);
con = udbq.getPooledConnection();
con.setAutoCommit(false);
if((!mode.equals("U")) || (mode.equals("U") && signatureIDIn == 0)) {
sql = "SELECT SEQ_SIGNATURE_ID.nextval FROM DUAL";
pstmt = con.prepareStatement(sql);
ResultSet rs = pstmt.executeQuery();
while(rs.next()) {
signatureID = rs.getInt(1);
if (fileName != null && imageType != null) {
sql = "INSERT INTO T_SIGNATURE (SIGNATURE_ID, SIGNATURE) values (?,?)";
InputStream is2 = new ByteArrayInputStream(fileData);
pstmt = con.prepareStatement(sql);
pstmt.setInt(1, signatureID);
pstmt.setBinaryStream(2, is2, (int)(fileData.length));
pstmt.executeUpdate();
pstmt.close();
con.commit();
con = null;
if(mode.equals("U") && signatureIDIn != 0) {
signatureID = signatureIDIn.intValue();
if (fileName != null && imageType != null) {
sql = "UPDATE T_SIGNATURE SET SIGNATURE = ? WHERE SIGNATURE_ID = ?";
InputStream is2 = new ByteArrayInputStream(fileData);
pstmt = con.prepareStatement(sql);
pstmt.setBinaryStream(1, is2, (int)(fileData.length));
pstmt.setInt(2, signatureID);
pstmt.executeUpdate();
pstmt.close();
con.commit();
con = null;
} catch (Exception e) {
con = null;
throw new Exception(e.toString());
return signatureID;

How to insert a table data into temporary table
Hi
Can anyone help me to insert a table data into temporary table.
Thanks
NavinIf you could provide a (simplified) example of the data you have and the output you're attempting to get, that would probably be quite helpful. I'm not sure that I understand exactly what you're trying to do here...
1) It sounds like you know the structure of the result set you're trying to generate. So it would be possible to create a temporary table once (at the same time that you create all your other tables) and write procedural PL/SQL code that would step through the data, write data to the temp table, select the data out of the temp table, and return a REF CURSOR. That would tend not to be the way that an Oracle developer would do things (there are exceptions, of course), but it would work.
2) I don't see any inherent problems in using sub-selects and inline views to do whatever aggregation you're trying to do on the secondary tables, which would allow you to get the output in a single query. For example, given an ORDERS table and an ORDER_DETAILS table,
SELECT o.customer_id, o.invoice_number, SUM( od.line_item_cost ) total_cost
FROM orders o,
order_details od
WHERE o.order_id = od.order_id
GROUP BY o.customer_id, o.invoice_number3) If you do need to use procedural logic, I would tend to look into the use of pipelined table functions or to read the data into an in-memory collection and to manipulate and return that collection.

How to insert java.util.Date to Oracle by OraclePrepaidStatement
Hi all,
I am trying to insert the date data to oracle a lot. But all of them works wrong???
Here's a code:
package main;
import oracle.jdbc.driver.*;
import oracledb.OraCon;
import java.text.SimpleDateFormat;
public class inmain {
* @param args
public static void main(String[] args)
OraCon conn = new OraCon();
conn.alloc();
String sql = "insert into test(c_Date, c_Float, c_Int, c_String) values (?,?,?,?)";
java.text.SimpleDateFormat MMddyyyyHHmmss = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
try
OraclePreparedStatement ps = (OraclePreparedStatement)conn.oraconnection.prepareStatement(sql);
String date = "12/12/2006 17:33:01";
java.util.Date ud = MMddyyyyHHmmss.parse(date);
java.sql.Date dd = new java.sql.Date(ud.getTime());
float ff = Integer.parseInt("1");
ps.setDate(1, dd);
ps.setFloat(2, ff);
ps.setInt(3, 4);
ps.setString(4, "This is test");
ps.executeUpdate();
catch(Exception e)
e.printStackTrace();
}Then I select from the table.
select to_char(test.C_DATE, 'yyyy-MM-dd HH24:mi:ss')
from test
Its result is:
2006-12-12 00:00:00
I wanna to show 2006-12-12 17:33:01.
How?Dear NiallMcG,

Since the two date attributes are coming in the W3C's xs:date format, you can directly define the corresponding columns as DATE and use a DATE projection in XMLTable :

Table altered
SQL> alter table try1 modify (fec date);

How to insert 3D Model data into an EPUB file?
Afternoon,
I am trying to insert a 3D model into an epub document. Does anybody know how to do this either within InDesign or with any other Adobe Program? The model I have is a Sketchup model and any export file type I try cannot be opened directly within InDesign.
In terms of working with an EPUB file Mac had the ibooks Author software which lets you insert Collada data and view a 3D Model within an ebook however this only lets me maintain my file as a ibook but in terms of the business I need to maintain EPUB compatibility as they are more uniformly compatible across our clientèle.
Can anyone shed some light on how to achieve the output I require?
Spoke to adobe support and they expressed about using 3rd party external coders to achieve this but i know very little about code unfortunately.
Regards,
GInDesign doesn't natively support placing 3D models. It would have to be done with coding. If you can't do the coding yourself, you may have to pay for the service from an EPUB coding expert. You could also investigate third party EPUB software to see if they support it. Here is a recently-mentioned example (I don't know if they support it):

How to insert multi language data to oracle database
Hi ,
Can any one suggest the steps involved in implementing storage/retrieval of data in the language otherthan english on the database?. I am using Oracle 9i database.
I want to write sql scripts to insert data to the database.How can i insert the data in the language otherthan english i.e hindi. ensuring storage and display of data is fine at the backend.
CHARACTERSET is set AL32UTF8 and need to insert the data in the NVARCHAR2 datatype enabled column.
Any suggestions would be greatly appreciated.
Thanks and Regards,
PoornimaIf you can write the text in Notepad, then enter the text and save the file with the encoding "Unicode big endian". Then, open the file in a hex editor. The first two bytes will be 0xFE and 0xFF (this is the Byte Order Mark). This code should be skipped for database storage as it is relevant to flat files only. What follows are two-byte character codes that you can put into UNISTR calls. The file with the word "Patra" will show up in the hex editor as:
FE FF 09 2a 09 24 09 4d 09 30
If you can enter the characters in your HTML browser, you can use the very useful conversion page at http://rishida.net/tools/conversion/ (this is not an official endorsement from Oracle but my personal advice). Enter the characters into the "Characters" text area and click on the corresponding [Convert] button. The "Hexadecimal code points" field will tell you the codes that you need to prefix with backslash and put into the UNISTR call.
If you are unable to enter the characters on your workstation, then you can identify each letter in the text and look it up in the Unicode character database at http://www.unicode.org/Public/UNIDATA/Index.txt or http://www.unicode.org/Public/UNIDATA/NamesList.txt. The four-digit hexadecimal codes listed there are what you are looking for. Unfortunately, such lookup will not work for Chinese Han and Japanese Kanji characters as they have no names in Unicode.
Another method is to use files in another language-specific encoding and convert them to Unicode before loading them into the AL32UTF8 database.

Remove the Try-Catch as this hides any errors that may be raised. It is unwise to use a Try-Catch this way, always when using a Try-Catch write code that alerts or writes to a log file. Also, there is no need for invoke Close method for the connection object,
the Using statement closes the connection for you.

OWB11gR2 - simple and easy way to load XML formatted data into db tables?
Hi,
we're currently trying to load table data stored in XML files into our datawarehouse using OWB 11gR2.
However, we're finding this is not quite as trivial as loading flat files...
Most postings on this forum points to the blog-entry title "Leveraging XDB" found here (http://blogs.oracle.com/warehousebuilder/2007/09/leveraging_xdb.html).
This blog also references the zip-file owb_xml_etl_utils.zip, which seems to have disappeared from it's original location and can now be found on sourceforge.
Anyway, the solution described is for OWB 10g, and when trying to import experts from the zip-file etc. we end up not being able to run the "Create ETL from XSD" expert, as the 11gR2 client is different from the 10g and does not have the Experts menu et.al.
Also, this solution was published over 3 years ago, and it seems rather strange that importing XML-formatted data should still be so cumbersome in the newer warehouse builder releases.
The OWB 11gR2 documentation is very sparse (or rather - quite empty) on how to load XML data, all it has is a few lines on "XML Transformations", giving no clue as to how one goes about loading data.
Is this really the state of things? Or are we missing some vital information here?
We'd have thought that with 11g-releases, loading XML-data would be rather simple, quick and painless?
Is there somewhere besides the blog mentioned above where we can find simple and to the point guidelines for OWB 11gR2 on how to load XML-formatted data into Oracle tables?
Regards,
-Haakon-Yes it is possible to use SQL*Loader to parse and load XML, but that is not what it was designed for and so is not recommended. You also don't need to register a schema, just to load/store/parse XML in the DB either.
So where does that leave you?
Some options
{thread:id=410714} (see page 2)
{thread:id=1090681}
{thread:id=1070213}
Those talk some about storage options and reading in XML from disk and parsing XML. They should also give you options to consider. Without knowing more about your requirements for the effort, it is difficult to give specific advice. Maybe your 7-8 tables don't exist and so using Object Relational Storage for the XML would be the best solution as you can query/update tables that Oracle creates based off the schema associated to the XML. Maybe an External Table definition works better for reading the XML into the system because this process will happen just once. Maybe using WebDAV makes more sense for loading XML to be parsed (I don't have much experience with this, just know it is possible from what I've read on the forums). Also, your version makes a difference as you have different options available depending upon the version of Oracle.
Hope all that helps as a starter.

How to insert data into Oracle db from MySQL db through PHP?
Hi,
I want to insert my MySQL data into Oracle database through PHP.
I can access Mysql database using mysql_conect() & Oracle database using oci_connect() through PHP.
Now How can I insert my data which is in MySQL into Oracle table. Both table structure are exactly same.
So I can use
insert into Oracle_Table(Oracle_columns....) values(Select * from MySQL_Table);
But again problem is I can't open both connections at the same time.
So has anyone done this before or anyone having any other idea..
Plz guide me...You can do it if you setup a ODBC Gateway between MYSQL and Oracle DB. Then you can directly read from MySQL table using DB links and insert into Oracle table in one single SQL Statement.
Otherwise you need to fetch the data from MySQL Into variables in your PHP Program and then insert into Oracle after binding the variables to the insert statement for Oracle. Hope that is clear enough.

how to insert more than 32k xml data into oracle clob column.
xml data is coming from java front end
if we cannot use clob than what are the different options availableAre you facing any issue with my code?
String lateral size error will come when you try to insert the full xml in string format.
public static boolean writeCLOBData(String tableName, String id, String columnName, String strContents) throws DataAccessException{
boolean isUpdated = true;
Connection connection = null;
try {
connection = ConnectionManager.getConnection ();
//connection.setAutoCommit ( false );
PreparedStatement PREPARE_STATEMENT = null;
String sqlQuery = "UPDATE " + tableName + " SET " + columnName + " = ? WHERE ID =" + id;
PREPARE_STATEMENT = connection.prepareStatement ( sqlQuery );
// converting string to reader stream
Reader reader = new StringReader ( strContents );
PREPARE_STATEMENT.setClob ( 1, reader );
// return false after updating the clob data to DB
isUpdated = PREPARE_STATEMENT.execute ();
PREPARE_STATEMENT.close ();
} catch ( SQLException e ) {
e.printStackTrace ();
finally{
return isUpdated;
Try this JAVA code.
