  • How to insert data from *.dmp file to  oracle 11g using Oracle SQL Develope

    hi
    i backup my database using PL/SQL developer and made *.dmp file
    how to insert data from *.dmp file to oracle 11g using Oracle SQL Developer 2.1.1.64
    and how to make *.dmp file from sql*plus ?
    thanks in advance

    Pl/Sql developer has a config window, there you choose the exec to do the import/export.
    Find it and his home version, it may be exp or expdp, the home version is the version of the client where the exp executable is.
    Then use the same version of imp or impdp to execute the import, you do not need to use Oracle SQL Developer 2.1.1.64. If you want to use it, you must have the same version in the oracle home that exp/imp of sql developer use.

  • How to extract data from .xltm file in a (dataset, datatable or a list) using wpf c#

    Hi all,
    As we can get data from .xls, .xlsx file in a dataset. Now i want to read all the entire data from .xltm file.
    I also want to get all sheets name from .xltm file. I am using .Net framework 4.5, Visual studio 2012.
    Please help me. I am unable to extract it. It is urgent.

    Hello Kalpna Bindal,
    I just investigate this issue and use the following way but it does work:
    private void Button_Click(object sender, RoutedEventArgs e)
    // initialize connection
    OleDbConnection con = new OleDbConnection();
    con.ConnectionString =
    "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\Fruits1.xltm;Extended Properties=\"Excel 12.0 Xml;HDR=YES;\"";
    //pass query to Insert values into Excel
    OleDbCommand cmd = new OleDbCommand();
    cmd.CommandText = "insert into [Sheet1$] values('')";
    cmd.Connection = con;
    // EXECUTE QUERY
    con.Open();
    cmd.ExecuteNonQuery();
    con.Close();
    I then did a research about this issue and find the following case:
    http://stackoverflow.com/questions/22225017/reading-excel-xltm-files-programmatically
    To test whether it is possible I use the following code in WPF:
    Microsoft.Office.Interop.Excel.Application xltmApp = new Microsoft.Office.Interop.Excel.Application();
    xltmApp.Visible = false;
    xltmApp.ScreenUpdating = false;
    Workbook xltmBook = xltmApp.Workbooks.Open(@"D:\Fruits1.xltm");
    Worksheet xlworksheet = xltmBook.Worksheets.get_Item(1);
    for (int i = 1; i <= 1; i++)
    for(int j=1;j<=1;j++)
    string str = (string)(xlworksheet.UsedRange.Cells[i, j] as Microsoft.Office.Interop.Excel.Range).Value;
    MessageBox.Show(str);
    The result is that I can read this .xltm file and read the firstline without problem.
    I would think you can also use this way to work with your .xltm file and output it to your application.
    For more details about how to fill to your WPF, common wpf and excel thread will be helpful:

    http://mozouna.com/Blog/2013/03/28/wpf-reading-and-writing-to-excel-file-with-c/
    By the way, for WPF case please post on WPF forum instead of C# forum.Best regards,

  • How to get data from a file?

    Hello everyone, i'm new to this forum and to java too. Ok, so here is what i want to do:
    I want to get data from a file containing words and numbers and store them into variables that i will use them after to insert into a database table. For example i have a file called employees.txt in this form:
    eid ename zipcode Hire_date
    1000 "Jones" 67226 "12-DEC-95"
    In C++ i declare variables for each data and store them, for example in this case:
    ifstream in("somefile");
    string name, hdate;
    int eid, zip;
    in >> eid >> ename >> zip >> hdate;
    So i want to do the same thing in JAVA but i can't make it work. So, i would appreciate if someone could give me a simple example how to do it. Thank you.

  • How to read data from a file in OSB

    hi guys,
    Recently, I've got a problem with reading file from specific location. I've actually followed this post OSB 11g - Read or Poll File in OSB - Oracle Fusion Middleware Blog, and then
    I know how to read a file. However, it does not as expected. Because, I've found no way to read data from the file. Therefore, no chance to manipulate the data like assigning to a variable, or extracting ....
    Hence, is there any way to read data from file by using proxy service in OSB ??? No Java code ???
    by the way, supposed that there is no way to read data from a file in OSB. So, What purposes will the way in the post above be used for?
    Many thanks in advance

  • How to write data into a file

    Hi
    I want to write data from a string into a file. I am created a directory and a .doc file . But when i write this data from a string into .doc file , its give an error : File not found exception
    But, when i check in my directory, a file is created with blank.
    My code is:
    import java.io.*;
    import java.util.*;
    import java.lang.*;
    class createFile {
         public static void main(String[] args) {
    try {
         String mss = "This is for dedo";
         FileInputStream fis;
         FileOutputStream fos;
    File file = new File("C:\\JD\\m4.rtf");
    // Create file if it does not exist
    boolean success = file.createNewFile();
         success = true;
    if (success) {
                   System.out.println("suc");     
                   fis = new FileInputStream(mss);
                   System.out.println(fis);
              fos = new FileOutputStream(file);
              int c;
                   while ((c = fis.read()) != -1) {
         fos.write(c);
                   System.out.println("mss");
              fis.close();
              fos.close();
         System.out.println("created");
    // File did not exist and was created
    } else {
    // File already exists
    } catch (IOException e) {
         System.out.println(e);
    regards
    madhu

    InputStream inputStream = new ByteArrayInputStream(mss.getBytes());Use this to push into the file>
    Ummm.... no. InputStreams are for reading, not for writing.
    Anyway, OP, you're making a mistake. You're trying to open a stream to a file called "This is for dedo". Use FileOutputStream(File file) constructor or FileOutputStream(String pathToFile). You can then wrap that stream with a PrintWriter or whatever you need.

  • How to load data from UTL file to database

    could anyone please advice me on above error.
    thanx.

    First of all, is file located on (or is accessible from) database server? If not - you can't load it neither with UTL_FILE nor with external table. You need to use client side tool like SQL*Loader or write your own client side load. If file is accessible from database server, then, as sb92075 noted, external table (assuming you are not on some ancient Oracle version) is the way to go.

  • How to write data from query into Real time cube?

    Hi All,
    Can anyone explain me step by step how to write data into a real time cube from front end queries.
    Thanks in advance

    Hi
    You can do this using Integrated Planning
    You need to create a aggregation level on the Real Time infocube and can create Planning function/sequence, Variables if needed.
    Then you can create query on this aggregation level and you can make the keyfigures Input ready in property pane and you can change the data and save it into cube.
    Please find below help link which clearly explains step by step about Integrated Planning like creating input ready queries etc.,
