Hi Peter,
you are right,at high level i was able to figure at these things.
But i don't know how to implement it using jdeveloper.
It will be more helpful if you can give me detailed steps to do it.
Thanks

  • Parse xml data and insert into database

    Hi Friends,
    I have an xml document which needs to be parsed and the data need to be inserted into an oracle database table.
    Please tell me which will be the easiest and optimal way of doing this.
    Thanks,
    Achayan

    Take a look at the JDOM xml parsing library - google for JDOM download or something.
    This will allow you to build an object representation of the XML doc, from which you can then extract the data.

  • Get the data  from excel and insert into the database

    I want to read the data from excel file, get the data from excel and insert into the database.

    You can use the Apache POI HSSF API to read data from Excel files and you can use the Sun JDBC API to insert data in database.
    This has nothing to do with JSP/JSTL.

  • Hi, extract data from xml file and insert into another exiting xml file

    i am searching code to extract data from xml file and insert into another exiting xml file by a java program. I understood it is easy to extract data from a xml file, and how ever without creating another xml file. We want to insert the extracted data into another exiting xml file. Suggestions?
    1st xml file which has two lines(text1.xml)

    RandomAccessFile? If you know where you want to insert it.Are you sure about this? If using this, the receiving file would have to have bytes inserted that exactly match the number of bytes replaced. I'm thinking that you'll likely have to stream through the second XML with a SAX parser and copy information (or insert new information) as you stream with an XML writer of some sort.

    If the files are small, you can load the target file in a DOM document, insert the data from the source file and persist the DOM.
    If the files are large, you probably want to use a StAX or SAX.

  • Convert flat file to XML document and store into Oracle database

    First:
    I have a flatfile and created external table to read that file in Oracle
    Now I want to create an XML document for each row and insert into Oracle database, I think that XMLtype.
    Could you please provide me some information/steps.
    Second:
    Is there performance issues, because everyday I need to check that XML document stored in the database against the in coming file.
    Thank You.

    Oracle 11g R2 Sun Solaris
    Flat file is | (pipe delimited), so I did create an EXTERNAL Table
    row1     a|1|2|3|4
    row2     b|2|3|4|5
    row3     c|6|7|8|9
    I want to store each record as XML document. So it will be easy to compare with next day's load and make insert or update.
    The reason is:
         First day the file comes with 5 columns
         after some days, the file may carry on some additional columns more than 5
         In this case I do not want to alter table to capture those values, if I use XML than I can capture any number of columns, CORRECT!. Please make me correct If I am wrong.
         This is the only reason to try to use the XMLType (XML Document)
         On Everyday load we will be matching these XML documents and update it if there is any column's value changes
    daily average load will be 10 millions and initial setup will be 60-80 millions
         Do I have anyother option to capture the new values without altering the table.
    Please advise!.

    Hi Sweety,
    Can you provide some more information? 
    The script for each of your queries.  (looking especially at how you are using single quotes around the Param properties for different data types)
    Are you using an Command SQL Query for the insert?
    Why are you using the Calculation action block instead of using the Expression Editor for the calculation?

    < unnecessary reference to personal blog removed by moderator >
    Here are the steps:
    1) First create a directory and grant read , write , execute to the user from where you want to access the flat files and load it.
    2) Write a generic function to load PIPE delimited flat files:
    CREATE OR REPLACE FUNCTION TABLE_LOAD ( p_table in varchar2,
    p_dir in varchar2 DEFAULT ‘YOUR_DIRECTORY_NAME’,
    P_FILENAME in varchar2,
    p_ignore_headerlines IN INTEGER DEFAULT 1,
    p_delimiter in varchar2 default ‘|’,
    p_optional_enclosed in varchar2 default ‘”‘ )
    return number
    is
    – FUNCTION TABLE_LOAD
    – PURPOSE: Load the flat files i.e. only text files to Oracle
    – tables.
    – This is a generic function which can be used for
    – importing any text flat files to oracle database.
    – PARAMETERS:
    – P_TABLE
    – Pass name of the table for which import has to be done.
    – P_DIR
    – Name of the directory where the file is been placed.
    – Note: The grant has to be given for the user to the directory
    – before executing the function
    – P_FILENAME
    – The name of the flat file(a text file)
    – P_IGNORE_HEADERLINES
    – By default we are passing 1 to skip the first line of the file
    – which are headers on the Flat files.
    – P_DELIMITER
    – Dafault “|” pipe is been passed.
    – P_OPTIONAL_ENCLOSED
    – Optionally enclosed by ‘ ” ‘ are been ignored.

    commit;
    RETURN L_ROWCOUNT;
    end TABLE_LOAD;
    Note: when you run the function then it will also modify the source flat file with timestamp , so that we can have the track like which file was loaded .
    3) Check if the user is having UTL_FILE privileges or not :
    SQL> SELECT OWNER,
    OBJECT_TYPE
    FROM ALL_OBJECTS
    WHERE OBJECT_NAME = ‘UTL_FILE’
    AND OWNER =<>;
    If the user is not having the privileges then grant “UTL_FILE” to user from SYS user:
    SQL> GRANT EXECUTE ON UTL_FILE TO <>;
    4) In the function I have used two tables like:
    import_hist table and badlog table to track the history of the load and another to check the bad log if it occurs while doing the load .
    Under the same user create an error log table to log the error out records while doing the import:
    SQL> CREATE TABLE badlog
    errm VARCHAR2(4000),
    data VARCHAR2(4000) ,
    error_date TIMESTAMP
    Under the same user create Load history table to log the details of the file and tables that are imported with a track of records loaded:
    SQL> create table IMPORT_HIST
    FILENAME varchar2(200),
    TABLE_NAME varchar2(200),
    NUM_OF_REC number,
    IMPORT_DATE DATE
    5) Finally run the PLSQL block and check if it is loading properly or not if not then check the badlog:
    Execute the PLSQL block to import the data from the USER:
    SQL> declare
    P_TABLE varchar2(200):=<>;
    P_DIR varchar2(200):=<>;
    P_FILENAME VARCHAR2(200):=<>;
    v_Return NUMBER;
    BEGIN
    v_Return := TABLE_LOAD(
    P_TABLE => P_TABLE,
    P_DIR => P_DIR,
    P_FILENAME => P_FILENAME,
    P_IGNORE_HEADERLINES => P_IGNORE_HEADERLINES,
    P_DELIMITER => P_DELIMITER,
    P_OPTIONAL_ENCLOSED => P_OPTIONAL_ENCLOSED
    DBMS_OUTPUT.PUT_LINE(‘v_Return = ‘ || v_Return);
    end;
    6) Once the PLSQL block is been executed then check for any error log table and also the target table if the records are been successfully imported or not.
