Advantages of storing data in XML

Hi --
I am working with Oracle Database for long time but i haven't used XML much during this time. I am just trying to figureout the advantages of storing the data in XML (XMLType column).
If i have millions of records in multiple tables, is there any advantage in terms of performance & management of data when i store the data in XMLType.
For example:
If i am storing employee details in a table, i can create bunch of columns in a table and store the data, or i can create an XMLType column and store the complete data in that column. I am trying to figureout whether storing in XML format is better than in separate columns, especially if i have lot of data.
Thanks for your time & help

Storing data in XML file

Hi,
I am a student and very new to XML. I know what it is but I never had developed anything in it.Now I am doing an assignment for which I need your help.
I have to store Customer data in XML file after he enters it in GUI.Customer is having the following fields:
String name1=BuyerGui.name.getText().trim();
String street1=BuyerGui.street.getText().trim();
int zipcode1=Integer.parseInt(BuyerGui.zipCode.getText().trim());
String city1=BuyerGui.city.getText().trim();
String country1=BuyerGui.country.getText().trim();
String email1=BuyerGui.eMailAddress.getText().trim();
I may have to update it some times.
I am working in Java 4.2. I heard that I can use JAXP but no idea how to do it.
Anybody help me with sample code because I dont have verymuch time for my assignment.
Thanks in advance,

Storing data from XML files in Oracle DB

Hi!
I just started to work with XML and need to save data from XML files into Oracle database. I tried to run sample from Oracle web site. The code was following:
public class xmlwritedb
public static void main(String args[]) throws SQLException
String tabName = "EMP"; // Table into which to insert XML data
String fileName = "emp.xml"; // XML document filename
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Initialize a JDBC connection
Connection conn =
DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@");
// Insert XML data from file (filename) into
// database table (tabName)
OracleXMLSave save = new OracleXMLSave(conn, tabName);
URL url = save.createURL(fileName);
int rowCount = save.insertXML(url);
System.out.println(" successfully inserted "+rowCount+
" rows into "+ tabName);
conn.close();
But it does not work.
OracleXMLSave object does not see file name.
Please, help me solve this problem. Also,where is it possible to find any documentation on oracle.xml.* classes API.
Thank you.
Maya.

Write / store xml data in Xe and retrieve stored data using pl/sql

Hi to all,
i'm searching a tutorial on:
A - how to write / store xml data in Xe and retrieve stored data using pl/sql
I don't want to use other technologies, because i use htmldb and my best practice is with pl/sql.
I was reading an ebook (quite old maybe) however it's about oracle 9 and it's talking about xmltype:
1 - I don't understand if this is a user type (clob/varchar) or it's integrated in Oracle 9 however i will read it (it's chapter 3 titled Using Oracle xmldb).
Please dont'reply here: i would be glad if someone can suggest me a good tutorial / pdf to achieve task A in Oracle XE.
Thanx

Thank you very much Carl,
However my fault is that i've not tried to create the table via sql plus.
Infact i was wrong thinking that oracle sql developer allows me to create an xmltype column via the create table tool.
however with a ddl script like the following the table was created successfully.
create table example1
keyvalue varchar2(10) primary key,
xmlcolumn xmltype
Thank you very much for your link.

Storing WDDX or XML Data

At the moment I am storing results from form data in a wddx
packet in a mediumtext field.
It all works fine but i'm sure there must be a cleaner
smarter solution. I have had to enable CLOBS on the datasource
recently.
It doesnt seem the best way of storing the information.
Does anybody know of a nicer solution, I am using mySQL but i
would be quite happy to move it over to MSSQL if I need to.
I have a feeling MSSQL has some sort of XML storage
functionality.
I don't really like the idea of writing to a file, it seems
far to 80's and i should imagine it gets harder and harder for
coldfusion to retrieve the file, the larger it gets.
Hope you can help
Regards
Matt

Matt,
We have been using WDDX to store form data in the data base
for a long time. I would say that storing it in XML is a better
route because most databases (SQL Server and Oracle is what I have
the most experience with) do have the capability to rip through XML
using X-path, etc. The best way though, that we have found out is
to have a "Properties" table. So it has a "PropertyName" column, a
"PropertyValue" column, a unique ID, and a Foreign Key ID to say a
"Report" table that is storing the form (config) data for. So then
you would query the "Properties" table, and get all the needed
values from it, and then do whatever it is you need to do in your
code based on those values.
Having a "Properties" table leverages itself way better to
reporting on the properties, where you can write a query to get
that information instead of having CF to dump that information.
Hope this helps.

Why we need to conver Context Node data into XML file----Export to Excel

Hi All,
Let me clarify my dought........today i have gone through the concept of "Exporting Context Data Using the Webdynpro Binary cache" in SAP Online Help.
From the SAP Online Help pdf document, i have found that, the context node data has been converted first in to XML file,after that file had been stored in the web dynpor binary cache...bla....bla.........
Here my qtn is why they had converted context node data into XML file. With out doing that can not we export context node data to excel file..?

Hi Sesshanna,
it is not neccessary to do that but xml has the advantage, that it can be easily transformed into every output format that might occur in later project stages.
If it's simply about blowing out some Excel, I suggest using an OSS library such as jexcelAPI or Jakarta POI and building the Excel how you need it.

What does this mean?
So I browse through forum & i got to know that i need to initial the UTL_FILE_DIR ="C:/OracleProject" in init.ora
So can i edit the init.ora with notepad.When i tried to do that it says permission denied
In my system it shows the init.ora file in path C:\oraclexe\app\oracle\product\10.2.0\server\config\scripts
but there is also other file initXETemp in the same path do i need to do the changes in it.
I have tried even editing the SPFILE as mentioned below:
C:\oraclexe\app\oracle\product\10.2.0\server\dbs\SPFILEEXE - I had edit this file using notepad & set the value of UTL_FILE_DIR ="C:/OracleProject". So next time when i restarted i'm unable to log on to the database.
So i had reinstall the software again.
Could you please let me know how to proceed..

Internal Table Data to XML

Hi
I have a requirement of writing internal table data to XML. Any idea where i should start.
I have pretty good experience with ABAP and basic knowledge in XML.
There are good blogs which talk about transformations and other stuff but they are not able to give me clear path to my solution.
Could somebody give me a basic example or some reference material where i can move the data in internal table (assume Sales order details of a day) to XML.
Thanks

Refer the program -
In this implementation we will only focus on the creation of the XML file and the transfer to the user. You can not create a XML document directly. You have to use a so called ixml factory first.
TYPE-POOLS: ixml.
DATA: l_ixml TYPE REF TO if_ixml.
l_ixml = cl_ixml=>create( ).
This iXML factory can create an empty XML document object named l_document.
DATA: l_document TYPE REF TO if_ixml_document.
        l_document = l_ixml->create_document( ).
At this point you can add the nodes (elements, attributes) into the document. First you have to declare the root element node.
DATA: l_element_root TYPE REF TO if_ixml_element.
This node we have to give a name and add it (create_simple_node) to the document object l_document, which will be the parent of this node.
l_element_root = l_document->create_simple_element(
            name = 'flights'
          parent = l_document ).
Next we can add child nodes to there parent node using the same method of the document object.
DATA: l_element_airline TYPE REF TO if_ixml_element,
l_element_airline = l_document->create_simple_element(
               name = 'airline'
             parent = l_element_root ).
An attribute can be add easily using the method set_attribute of the element node.
l_rc = l_element_airline->set_attribute( name = 'code' value = 'LH401' ).
Now we have finished the document object. Regretfully it can not be displayed in any form due to the fact that it is a binary object.
The next step is to convert the created document to a flat file. To achieve this we have to create a stream factory, which will help us to create an output stream.
DATA: l_streamfactory   TYPE REF TO if_ixml_stream_factory.
l_streamfactory = l_ixml->create_stream_factory( ).
In this case, we will convert the document into an output stream which is based on an internal table of type x.
TYPES: BEGIN OF xml_line,
          data(256) TYPE x,
        END OF xml_line.
DATA: l_xml_table       TYPE TABLE OF xml_line,
        l_xml_size        TYPE i,
        l_rc              TYPE i,
        l_ostream         TYPE REF TO if_ixml_ostream.
l_ostream = l_streamfactory->create_ostream_itable( table = l_xml_table ).
When we have created the output stream we can do the rendering from the document into the stream. The XML data will be stored in the internal table automatically.
DATA: l_renderer        TYPE REF TO if_ixml_renderer.
l_renderer = l_ixml->create_renderer( ostream = l_ostream
                        & nbsp;              document = l_document ).
l_rc = l_renderer->render( ).
In the last step we upload the file to the sapgui
l_xml_size = l_ostream->get_num_written_raw( ).
CALL METHOD cl_gui_frontend_services=>gui_download
   EXPORTING
     bin_filesize = l_xml_size
     filename     = 'c:\temp\flights.xml'
     filetype     = 'BIN'
   CHANGING
     data_tab     = l_xml_table
   EXCEPTIONS
     OTHERS       = 24.
This finished the first step-of-three. As mentioned before the next log will focus on the conversion from xml files (back) to abap tables.
REPORT z_xit_xml_dom_create.
TYPE-POOLS: ixml.
TYPES: BEGIN OF xml_line,
          data(256) TYPE x,
         END OF xml_line.
DATA: l_ixml            TYPE REF TO if_ixml,
        l_streamfactory   TYPE REF TO if_ixml_stream_factory,
        l_ostream         TYPE REF TO if_ixml_ostream,
        l_renderer        TYPE REF TO if_ixml_renderer,

Calling stored procedure with XML XSU

Hi Guys,
I am using XML SQL Utility api for inserting xml data in to oracle database.Now my requirement is I have to return inserted record sequence value(i.e primary key) back and have to resend it to insert child table data as a foreign key.We can do with PL SQl. Can you guys suggest me how to call a stored procedure using xml sql utility.
Thanks,
Srinivas.

If anyone has figured this one out let me know. I'm getting the same problem. Only in my case I've tried both the "OraOLEDB.Oracle" provider and the "MSDAORA" provider and I get an error either way. Also my procedure has 2 in parameters and 1 out parameter. At least now I know I'm not the only one with this issue. :)
'*** the Oracle procedure ***
Create sp_getconfiguration(mygroup in varchar2, myparameter in varchar2, myvalue out varchar2)
AS
rec_config tblconfiguration.configvalue%type;
cursor cur_config is select configvalue from tblconfiguration where configgroup = mygroup and configparameter = myparameter;
begin
open cur_config;
fetch cur_config into rec_config;
close cur_config;
myvalue := rec_config;
end;
'** the ado code ****
dim dbconn as new adodb.connection
dim oCmd as new adodb.connection
dim ors as new adodb.recordset
dbconn.provider = "MSDAORA" 'or dbconn.provider = "OraOLEDB.Oracle"
dbconn.open "Data Source=dahdah;User ID=didi;Password=humdy;PLSQLRSet=1;"
set ocmd.activeconnection = dbconn
cmd.commandtext = "{call fogle.sp_getconfiguration(?,?)}"
'i've also tried creating a public synonym called getconfiguration and just refering to procedure by that.
' "{call getconfiguration(?, ?)}"
' "{call getconfiguration(?,?, {resultset 1, myvalue})}"
'and numerous numerous other combinations
set oPrm = cmd.createparameter("MYGROUP", advarchar, adparaminput, 50, strGrouptoPassIn$)
cmd.parameters.append oPrm
set oPrm = cmd.createParameter("MYPARAMETER", advarchar, adParamInput, 50, strParameterToPassIn$)
cmdParameters.append oPrm
set rs = cmd.execute

10.1.3 Migration Issue with data-sources.xml

Hi:
Running into lots of migration issues for an application built in 10.1.3 EA, migrating to 10.1.3. production, mostly in the BC project. Here's one: the database connections built in EA were not carried over to prod, so they needed to get re-built. No biggie. But now the data-sources.xml file in the model project has duplicate entries for my data sources. I have tried directly editting that file and removing the duplicates, but when I go to run my application (ADF Faces & ADF BC) JDeveloper hangs. When I abort JDev and re-start it, the duplicate entries are back in data-sources.xml (and yes, I did save the file after making the changes). It seems that the xml file is built dynamically from definitions stored elsewhere. Where is the source? What will I need to modify to get the changes to take?
Thanks.
Johnny Lee

There is new control over when/whether JDeveloper add/updates your data-sources.xml file for the embedded server. The settings are located here:
Tools | Embedded OC4J Server Preferences | Current Workspace | Data Sources
There are some settings there that control whether/when we update the data-sources.xml

SAX, incor. data for XML element, XML 1.1 doc (1.0 ok) in JRE 6 (JRE 5 ok)

Hello,
for some reason, the test case below fails when driven with Java 6. Looks like, when long string data is stored in a XML element, DocumentHandler's characters() method will be provided with incorrect data.
With XML 1.0, parsing works fine in all my tests, Apache Xerces, JRE 5, JRE 6.
With XML 1.1., parsing works fine with Apache Xerces, JRE5 but not with JRE6.
I've checked it with latest JRE 6 update 4.
Anyone else xperiencing such problems with XML1.1 parsing when using JAXP bundled with Java 6?
I've tried to file a bug at bugdatabase, but for some reason I got no response for my issue - so I'm trying the forum now ;-)
Thanx for comments

thanx, DrClap, haven't seen the "code" button for some reason, code is attached again
The output of my test is like this for JRE6 (truncated)
xml_sun 456789 This is is some text 0. 0123456789 This is some text 1.
xml_apache 0123456789 This is some text 0. 0123456789 This is some text 1.
Notice, xml_sun not only starts wrong ("0123" missing) - for some reason, the text there is not "This is some text" but "This is is some text" - very interesting in a way. I guess there's an issue with repeated text chunks ...
So, the data in my XML element is kind of changed, the length of the string is okay but the characters are "misplaced" or so :-) I thought about a problem with StringBuffer first, but the StringBuffer works fine for Apache ... so I really think there's an issue with JRE 6's parser for XML 1.1

Use of cache_scheme in data-sources.xml

Hi guys.
I have posted a couple of similar topics before - without any response ! I can't believe with all of the gurus out there that NOBODY knows the answer to this ! :-)
Anyway, we are providing a 'vanilla' type implementation of Oracle's Connection Pooling - just using Oracle's DataSource to open and close connections, and having Oracle dynamically take care of the pooling itself. ( Apparently, under this scenario, even max and min connections are set as required ).
However, if I specify the cache_scheme property within data-sources.xml, will it take effect using this basic implementation ? In other words, will changing it's value effect the behaviour once the max limit is reached and more connections are requested ?
Many thanks.
Steve.

Timo,
thanks for your respone! I managed to configure the application to use a data-source connection created on the application server. Also in order to be able to deploy the same EAR to a number of containers on different DB's.
I know it's possible to connect to a DB without using a data-sources.xml file .. but it seemed like my application was storing some 'old' connection information because it was able to connect to the db without having the data sources configured on the AS.
Do you need to restart JDeveloper after unchecking the 'Bunde default data-sources.xml during deployment' checkbox? Because it is working correctly right now ... .
Thanks,
Koen Verhulst

Saving adobe form data to XML

Am trying to see what happens when user fills in adobe form and clicks submit. What will be sent back to server? Filled PDF or XML? If its XML, does it get stored on the user's machine in some temporary files?? If not, atleast where does it get stored on the server?
Am basically trying to develop a functionality where user clicks submit and all the form data gets stored in an XML file on the local machine. Any inputs?

Hi Narayana,
You can use Web Dynpro Java with embedded Interactive PDF forms; and within your WDJ application, you can call various 'models': web services, EJBs and BAPIs/RFCs etc.
So to pass data to an SAP system, you don't automatically need the XML data as a BAPI is sufficient. Check out <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/developerareas/webdynpro?rid=/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d#backend">these SDN tutorials</a> to do this.

Getting data via "XML Data" connectivity

Hi,
I need to retrieve data in Dashboard Design SP2 from one table stored on a SQL Server 2000. As I need to refresh the data I only have the option to use the "XML Data" connection (we are using BO4.0 Edge and can't use QaaWS).
However, I am completly new in this XML topic... In which way should data be delivered so that I can use it in Dashboard Design (in Data Manager -> "XML Data" I have to input a "XML Data URL"...)?
Thanks!

Hi steve,
Please refer below tutorial. It shows an example to create dashboard with XML file as data source.

Hope it helps you.

Read data from xml files and populate internal table

Hi.
How to read data from xml files into internal tables?
Can u tell me the classes and methods to read xml data..
Can u explain it with a sample program...

<pre>DATA itab_accontextdir TYPE TABLE OF ACCONTEXTDIR.
DATA struct_accontextdir LIKE LINE OF itab_accontextdir.
DATA l_o_error TYPE REF TO cx_root.
DATA: filename type string ,
             xmldata type xstring .
DATA: mr      TYPE REF TO if_mr_api.
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
WRITE xmldata.
TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.
LOOP AT itab_accontextdir INTO struct_accontextdir.
    WRITE: / struct_accontextdir-context_id,
           struct_accontextdir-context_name,
           struct_accontextdir-context_type.
    NEW-LINE.
    ENDLOOP.</pre>
<br/>
Description:
In the above code snippet I am storing the data in an xml file(you know xml is used to store and transport data ) called 'xml_accontextdir.xml' that is uploaded into the MIME repository at path 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'.
The below API is used to read a file in MIME repo and convert it into a string that is stored in ' xmldata'. (This is just a raw data that is got by appending the each line of xml file).
mr = cl_mime_repository_api=>get_api( ).
mr->get( EXPORTING i_url     = 'SAP/PUBLIC/BC/xml_files_accontext/xml_accontextdir.xml'
              IMPORTING e_content = xmldata ).
    Once the 'xmldata' string is available we use the tranformation to parse the xml string that we have got from the above API and convert it into the internal table.
<pre>TRY.
CALL TRANSFORMATION id
      SOURCE XML xmldata
      RESULT shiva = itab_accontextdir.
CATCH cx_root INTO l_o_error.
ENDTRY.</pre>
Here the trasnsformation 'id ' is used to conververt the source xml 'xmldata' to resulting internal table itab_accontextdir, that have same structure as our xml file 'xml_accontextdir.xml'. In the RESULT root of the xml file has to be specified. (In my the root is 'shiva').
Things to be taken care:
One of the major problem that occurs when reading the xml file is 'format not compatible with the internal table' that you are reading into internal table. Iin order to get rid of this issue use one more tranformation to convert the data from the internal table into the xml file.
<pre>TRY.
      CALL TRANSFORMATION id
        SOURCE shiv = t_internal_tab
        RESULT XML xml.
    CATCH cx_root INTO l_o_error.
ENDTRY.
WRITE xml.
NEW-LINE.</pre>
<br/>
This is the same transformation that we used above but the differnce is that the SOURCE and RESULT parameters are changed the source is now the internal table and result is *xml *string. Use xml browser that is available with the ABAP workbench to read the xml string displayed with proper indentation. In this way we get the format of xml file to be used that is compatable with the given internal table.
Thank you, Hope this will help you!!!
