  • Generate XML Schema from Oracle Database

    Is there a utility that would allow our team to generate XML Schemas directly from existing Oracle databases? Or do you have a suggestion on how to achieve this?
    Thank you.

    Hey, The Schema Processor is available in the Technologies section on this site. Just download it and see the samples. You will get the way for doing it. If you are having problems then just call me.

  • To generate XML output from Oracle Apps 11

    Hi Anyone has the experience to generate the output from Oracle Apps 11 as XML file? Database is 8.17, Oracle Apps 11. The concurrent program can be written in PL/SQL or can report 2.5 generate the output as XML?
    The scenario is:
    1) Run a concurrent program in Oracle Apps 11
    2) Output generated is XML (.xml)
    Regards.

    This forum is for Oracle XML DB features. XML DB is only available as of database 9iR2.

  • Can you generate XML schema from XMLDB?

    I have not used XMLDB and don´t read the entire doc about the product(sorry for that).
    I got the following question, is it possible to generate a XML schema from relational data through XMLDB? Or is this best done via a third party software like XMLSpy or alike?

    3rd Party Software...
    We can generate a schema for an object Hierarchy but our considered opinion is that there is no sensible way to generate an XML Schema representation of a purely relational data structure. It requires a tool which allows you to make decisions on how to organize the heirarchy.

  • Generate XML Schema from Java classes?

    Hi,
    Considering an XML Mapping, i would like to generate a default XML Schema from my Java class.
    Is there a tool in toplink (10.1.3) to do that or does anyone have an easy way to generate this XML schema?
    Thanks,
    Ludovic

    Hi Ludovic,
    We don't have support for schema generation from Java classes in TopLink 10.1.3. It's required for JAXB 2.0 so it will be available in a future release.

    Could anyone please explain how to generate a xml file from a database table.examples will be highly appreciated.

    See the release notes for our XSQL Pages component of the Java XDK for a tutorial. There are also lots of examples in Building Oracle XML Applications.
    You use the XML SQL Utility component to accomplish the task. It's part of our Java XDK that you can download from http://otn.oracle.com/tech/xml

  • Need help for SQL SELECT query to fetch XML records from Oracle tables having CLOB field

    Hello,
    I have a scenario wherein i need to fetch records from several oracle tables having CLOB fields(which is holding XML) and then merge them logically to form a hierarchy XML. All these tables are related with PK-FK relationship. This XML hierarchy is having 'OP' as top-most root node and ‘DE’ as it’s bottom-most node with One-To-Many relationship. Hence, Each OP can have multiple GM, Each GM can have multiple DM and so on.
    Table structures are mentioned below:
    OP:
    Name                             Null                    Type        
    OP_NBR                    NOT NULL      NUMBER(4)    (Primary Key)
    OP_DESC                                        VARCHAR2(50)
    OP_PAYLOD_XML                           CLOB       
    GM:
    Name                          Null                   Type        
    GM_NBR                  NOT NULL       NUMBER(4)    (Primary Key)
    GM_DESC                                       VARCHAR2(40)
    OP_NBR               NOT NULL          NUMBER(4)    (Foreign Key)

    I am using above SQL select statement for fetching the XML records and this gives me all related xmls for each entity in a single record(OP, GM, DM. DE). Output of this SQL query is as below:
    Current O/P:
    <resultSet>
         <Record1>
              <OP_PAYLOD_XML1>
              <GM_PAYLOD_XML1>
              <DM_PAYLOD_XML1>
              <DE_PAYLOD_XML1>
         </Record1>
         <Record2>
              <OP_PAYLOD_XML2>
              <GM_PAYLOD_XML2>
              <DM_PAYLOD_XML2>
              <DE_PAYLOD_XML2>
         </Record2>
         <RecordN>
              <OP_PAYLOD_XMLN>

              <DM_PAYLOD_XMLN>
              <DE_PAYLOD_XMLN>
         </RecordN>
    </resultSet>
    Now i want to change my SQL query so that i get following output structure:
    <resultSet>
         <Record>
              <OP_PAYLOD_XML1>
              <GM_PAYLOD_XML1>
              <GM_PAYLOD_XML2> .......
              <GM_PAYLOD_XMLN>
              <DM_PAYLOD_XML1>
              <DM_PAYLOD_XML2> .......
              <DM_PAYLOD_XMLN>
              <DE_PAYLOD_XML1>
              <DE_PAYLOD_XML2> .......
              <DE_PAYLOD_XMLN>
         </Record>
         <Record>
              <OP_PAYLOD_XML2>
              <GM_PAYLOD_XML1'>
              <GM_PAYLOD_XML2'> .......

    Appreciate your help in this regard!

    Hi,
    A few questions :
    How's your first query supposed to give you an XML output like you show ?
    Is there something you're not telling us?
    What's the content of, for example, <OP_PAYLOD_XML1> ?
    I don't think it's a good idea to embed the node level in the tag name, it would make much sense to expose that as an attribute.
    What's the db version BTW?

  • Generate XML file from DB table

    Hi all,
    I am trying to retrieve data from a DB table and generate an XML file.
    I am using Oracle8i and IIS 4.0. I have downloaded XML parser for PL/SQL and XSQL Servlet. Also I have Jrun to enable IIS to process Jservlets
    Here are my questions,
    1. Do I need any other software ?
    Also do I need both XML parser for PL/SQL and XSQL Servlet ??
    2. What is the next step I should do ?
    Please help me. Thanks in advance.
    Vikki

    You downloaded the wrong XML Parser!
    XSQL requires Java Parser. Well, there's a copy included with the XSQL package so you actually don't need to do another download.
    You really don't need XSQL if you just want a XML file from DB, you just needed a XML SQL Utility. Download that and run the samples.

  • How to generate XML file from oracle database query result

    Hi dudes,
    as stated on the subject, can anyone suggests me how can i achieve the task stated above??
    Here is a brief description of my problem:
    I need to create a XML file once i query from the oracle database, and the query result returned from the database will be stored in XML file.
    I'd searched around the JAXB, DOM, SAXP and the like basic concepts, but i still don't know how to start??
    Any suggestions ???

  • XML in Oracle 9i (best method to return a xml file from a table query)

    Hello.
    What is the best method to query a table, or set of tables (that will return thousands of rows) using xml in oracle? (best performance)
    I'm currently using DBMS_XMLGen, is there a better method ?

    I think, if your talking about generating XML, that you should use XMLElement, XMLForest, etc. to create your XML.
    Lets assume that you base is relational data, then maybe the following great example will give you an idea how to do it : Re: Generate XML Schema from oracle tables
    As michaels pointed out (did you read the link/ URL given?), the general expectancy is that the packages will be less and less important. So also maintenance wise the XMLElement, etc way will be the best, also for the future, maintainable method.

  • Generating xml from oracle table

    Thanks in advance

    Hi,
    DBMS_XMLQUERY is a wrapper for methods from the Java class "oracle.xml.sql.query.OracleXMLStaticQuery".
    The problem is that Oracle 10g XE doesn't have a JVM, so you can't use this package.
    Use DBMS_XMLGEN instead, it provides similar functionalities and is more efficient (C-based) :
    SQL> var g_clob clob
    SQL> DECLARE
      2    l_ctx    dbms_xmlgen.ctxHandle;
      3  BEGIN
      4    l_ctx := dbms_xmlgen.newContext('select * from scott.emp');
      5    :g_clob := dbms_xmlgen.getXML(l_ctx);
      6    dbms_xmlgen.closeContext(l_ctx);
      7  END;
      8  /
    PL/SQL procedure successfully completed.
