  • 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 file

    Hi 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();
                FileItem fileItem = (FileItem);
                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 {
                con = udbq.getPooledConnection();
                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( {
                       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));
                        con = null;
                if(mode.equals("U") && signatureIDIn != 0) {
                    signatureID = signatureIDIn.intValue();

  • How to load PDF files into oracle database and display them in APEX

    Hi All,
    We have a requirement for loading the Loading PDF files (lots of PDf files) to the oracle database and then display the PDF files in the Oracel APEX report.
    So that User can view the PDF files. Our current APEX verison is 3.2..
    Please let me know how to implement it and where to find the sample application!
    Thanks in advanced!

    Thanks Tony for your quick response!
    We need to load a lot of PDfs (history + current).
    I have a questions about the SQL loader. I am trying to insert a pdf file into a table by following the oracle loading sample:
    Example Data File: loader2.dat
    This file contains the data to be loaded into each row of the table, articles_formatted.
    Each line contains a comma separated list of the fields to be loaded in articles_formatted. The last field of every line names the file to be loaded in to the text column:
    Ben Kanobi, plaintext,Kawasaki news article,../sample_docs/kawasaki.txt,
    But i don't know to where should I put my pdf file on the server.
    for example:
    Where is the file 'kawasaki.txt'??
    I try my local path, it didn't work. like c:\temp.
    then I loaded teh PDf file into our server(/findev20/olmtest/orafin/11.5.7/olmtestcomn/temp) , and In my data file. I put the path
    1, pdf_emp1,../findev20/olmtest/orafin/11.5.7/olmtestcomn/temp
    but I got the error: the system can not find the file specified.
    Where should I put the PDf files on the server and how to specify the path in the data file?

    This is not something that can be answered easily. There is quite alot of code involved....
    To get started I suggest you read up on the built-in package 'DBMS_LOB' from Oracle . Most of what you need you should find there.
