Usage

From source file:Main.java

    createBlobClobTables(stmt);//ww  w . j av  a2 s.  c  om

    PreparedStatement pstmt = conn.prepareStatement("INSERT INTO BlobClob VALUES(40,?,?)");

    File file = new File("blob.txt");
    FileInputStream fis = new FileInputStream(file);
    pstmt.setBinaryStream(1, fis, (int) file.length());

    file = new File("clob.txt");
    fis = new FileInputStream(file);
    pstmt.setAsciiStream(2, fis, (int) file.length());
    fis.close();

    pstmt.execute();

    ResultSet rs = stmt.executeQuery("SELECT * FROM BlobClob WHERE id = 40");
    rs.next();

    java.sql.Blob blob = rs.getBlob(2);
    java.sql.Clob clob = rs.getClob("myClobColumn");

    byte blobVal[] = new byte[(int) blob.length()];
